Type depository. Holotype male in MNHN, paratype male and female in SDEI.

Type status. Paratype male in SDEI, type labels: “ Albay, S. Luzon, Whitehead, 94; Type coll. W. Horn; Coll. W. Horn, DEI Eberswalde; Tring Mus.; Paratypus [printed, red]” . Paratype female in SDEI, type labels: “ N. Luzon, ( Whitehead . 94); Type, coll. W. Horn; Tring Mus. ; Paratypus [printed, red]; Coll. W. Horn, DEI Eberswalde ; Rothschildi mihi [pale yellow, hand written, bordered black]” .

Other material examined. 3 females in SDEI: “ N. Luzon, Whitehead ” . 1 male in BMNH: “ N. Luzon ” .

Distribution. Philippines, Luzon (Prov. Albay, all records are from North Luzon).

Diagnosis. Distinguished by the reddish femora and the unicolored glossy coppery or greenish elytra.

Re-description. Size: Total length (without labrum) 5.5–6.5 mm (mean = 5.9 mm, n = 6). Head: Blue green or coppery green above, genae dark blue, surface smooth, glabrous, with each two setigerous punctures next to the eyes in front and at the center; strong longitudinal striae on vertex and orbital plates, the striae becoming slightly concentric on vertex, and finer, irregular, transversely waved, behind on neck; genae roughly longitudinally striated. Eyes pale yellow. Ratio between width of head and elytra = 1.1 in medium. Labrum (male Fig. 40, female Fig. 41) distinctly wider than long, ratio between width and length = 1.9 in medium; with six to seven marginal setae, unidentate in the middle of front edge; color rufous, at base and lateral margins with green hue in various expansion. Mandibles yellowish all over. Labial and maxillary palpi testaceous, the last joint metallic dark; basal segment of labial palpi with long erected white setae. Antennae slender, long, reaching half of the elytral length in the females, may be a little longer in males (antennae of the studied material mostly broken); scape yellowish, with one long apical seta; antennomeres two to four brownish, antennomeres five to eleven dark brown, dull, finely and evenly pubescent. Thorax: Pronotum as wide as long (ratio between width and length = 1.0 in medium), straight at sides, glabrous, transversely waved before and behind the transversal constrictions and at the lateral margin, with irregular wrinkles on disc; color blue green or coppery green, margin violet. Sternae and episternae dark brassy, glabrous all over; mesepisternum of females with a shallow longitudinal furrow over its entire length. Elytra: ( Fig. 37–38) parallel-sided; color green or coppery, lateral margins bluish, apex semi-translucent; elytral testaceous maculation absent, or consists of a slender middle dot, or of a tiny subhumeral, slender middle and small subapical dot. Surface with evenly spaced punctures, shallow to absent apically, shoulders glossy; preapical impression shallow, apical microserration extremely fine; apical border distinctly rounded and restricted towards middle suture, with a tiny sutural spine. Epipleurae rufous. Ventral aspect: Venter glabrous, brownish black; coxae with some white setae, testaceous; trochanters glabrous and testaceous; femora testaceous; tibiae dark brownish testaceous at base; tarsi dark brownish; legs covered with some white setae, mesotibiae more densely setose. Aedeagus: ( Fig. 39) on left lateral view fusiform, stout and straight, tapering, slightly enlarged in the middle, with a short, straight, blunt and slightly upturned apex (total length 2.0 mm).

Remarks. All but one of the beetles in collections show the label data “N Luzon”, without further details Only one bears the label data “ Albay, S Luzon”. Therefore, the distribution of C. rothschildi is not absolutely known.
