1. Ugyops kinbergi Stal , Hemiptera,

Konig!. Sven. Freg. Eugenies Resa,

Zoologi 4: 274, pl. 4, fig. 2, 2 a, b, 1859. (See figure 2, a-d.)

Crown elongate, narrow, about three times as long as the basal width. Frons elongate, narrow between the eyes, somewhat widened ventrally; the median carina forking on the basal third, the two branches running parallel to each other to the apex of the head where they are united for a short distance on the median line and then diverge and are connected with the lateral margins of the crown a short distance before the posterior margins of the crown. Antenna! segments subequal; the first somewhat club-shaped; the second terete, densely pustulate; the flagellum longer than either segment, but not as long as both segments combined.

Male genitalia with the pygofer rather robust, about twice as long as its greatest width; the ventral emargination a deep triangle with the median area produced into a short tongue-like tooth; genital styles elongate, slender, their bases approximate, rather robust, the stems diverging for about half their length and gradually reduced in size; the apical half bent, more acuminate, meeting on the median line; the apices appressed, slender, acuminate; diaphragm with the dorsal margin broadly circularly excavated without genital armature; anal segment short, ventral margin broadly excavated, no anal spines; anal style short, broadly triangular, greatly flattened; aedeagus a much elongate coiled tube.

General color of the paler specimens ochraceous yellow with the eyes brown and with a faint indication of marbling on the lateral areas of the head in front of the eyes. Tegmina yellowish subhyaline and the apical fourth posterior to the branches of media brownish fuscous; with small brownish fuscous spots along the apical border of the cells between the costal border and media; with a small fuscous spot at the apex of clavus on the commisural margin; the posterior apical area of the hind wing infuscated. The specimens with intermediate coloration are colored about as in Stal's description. There is, however, a single darker female which has the general color smoky testaceous with very heavy fuscous markings on the lateral areas of the frons and on the sides of the head in front of the eyes. There is also a broad fuscous vitta starting behind the eyes and extending across the lateral fields of the pronotum, mesonotum and across the clavus to the apex of the tegmina.

This species was described originally from Ponape, Caroline Islands. It has since been recorded from Java but not elsewhere in the Pacific. There is a series in the present collection which agrees in all essential details with Sta.l's short description and with his illustrations except that, in general, the specimens before me seem to be more heavily marked with fuscous on the body and on the tegmina than Sta.l's description and illustration would seem to indicate. However, the other details agree so well that I consider it best to fix Sta.l's name upon the present specimens rather than to erect a new species for them. Sta.l's illustrations do not show the suture between the clypeus and the frons, and he does not illustrate the genitalia; I have, therefore, included the most outstanding characteristics which supplement his short description, and have illustrated the genitalia.
