5. Calloeneis jacquelyn Gordon and Hanley , new species

Description. Male holotype. Length 1.5 mm, width 1.4 mm; dorsal surface shiny except elytron weakly alutaceous. Color yellow; pronotum dark brown with lateral 1/3 yellow; elytron slightly darker yellow with large, dark brown apical macula ( Fig. 17, 20 ). Head with dense punctures separated by less than a diameter; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated less than to twice a diameter; prosternal punctures small, indistinct, separated by about a diameter; mesosternal punctures larger than on prosternum, separated by less than a diameter, metasternal punctures small, separated by two to four times a diameter medially, absent in lateral 1/3; basal abdominal ventrite with coarse punctures in median 1/3 separated by less than to twice a diameter, ventrite 2 coarsely punctured in median 2/3, punctures separated by less than a diameter, ventrites 3, 4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided, medially depressed, 1.2 times as wide as eye, clypeal apex weakly curved ( Fig. 18 ); eye canthus short, about half width of eye. Prosternum with lateral carina on each side curved, extended from apex of intercoxal process to lateral margin of prosternum. Epipleuron not descending externally. Genitalia lost.

Female. Similar to male except head brown, lateral 1/3 of elytron dark yellow; genitalia with ramus of spermathecal capsule wide, cornu narrowed medially, apex of cornu broadly rounded ( Fig. 19 )

Variation. Length 1.5 to 1.8 mm, width 1.4 to 1.5 mm. Elytron dark brown with large, oval, median yellow macula, macula sometimes expanded over most of elytron.

Type material. Holotype; Captured on cocoa, I.C.T.A., St. Augustine, Trinidad BWI, Jan. 10. 1954, Collector F. D. Bennett, Delphastus sp.?n. Det. R. D. Pope 1955, Pres. by Comm Inst ent B.M. 1981-315. ( BMNH) . Paratype, 1, labels same as holotype. ( BMNH).

Other specimens. 5, one specimen, Port of Spain, Trinidad, N. M. Rohwer, 5-2-25 coll .; one specimen, Imperial College Trinidad BWI, Jan. 21, 1936, SM Dohanian ; three specimens, Dept. Agr. grounds, Port-of-Spain, Trinidad, Oct. 10, 24, Nov. 2, 1918, A-764, A-825, A-868, Harold Morrison. ( USNM) .

Remarks. This is another species recognized by dorsal color pattern although variation is considerable. This difference is probably simple variation as some specimens bear identical collection labels. Examples listed under “Other specimens” are probably conspecific with the types but are not so designated. Geni- talia described were obtained from one of those specimens.
