slightly sinuate, narrowly depressed, still narrower toward the 

 humeral angles but also visible throughout from above, the basal 

 margin broadly and very slightly sinuate. Scutellum perfectly 

 plane. Elytra reaching apex of abdomen. Abdomen with the 

 apical angles of the fifth segment very slightly prominent, venter 

 not sulcated, male genital segment impressed at the middle of 

 the apical margin, which is rounded, with a shallow arcuate 

 sinuosity in the center (much as in C. hebeticollL^ Bredd.). 

 Femora beneath with a few minute teeth in the apicaJ half. 



Length, male, 10.5 millimeters. 



Luzon, Laguna, Mount Banahao. 



Of one antenna only the first two joints remain. The other 

 antenna is abnonnally developed, the second and third joints 

 being fused into one, which is thicker and somewhat longer 

 than the normal second joint; the robust fourth joint is about 

 half the length of the first, but is possibly somewhat different 

 in normal antennse. 



I place this species provisionally in Breddin's subgenus Micro- 

 colpura near Colpura tuhercuUcollis Bredd., from which it differs 

 in the structure of the male genital segment and in several other 

 details. However, as the single entire antenna is abnormal 

 and the female is unknown, it is not impossible that it will 

 prove to belong to Sciophynis Stal or to Xanthocolpura Bredd.^ 

 It agrees well with Vittorius Dist. in all essential points, but 

 whether Vittoi-ius is a valid genus is impossible to know as 

 Distant, although he had a female specimen before him, has 

 not described the genital characters of this sex. In this dif- 

 ficult group it is absolutely necessary to know the genital 

 characters. - 



Professor Baker has found Colpura obscuricomis Stal on 

 Mount Maquiling and C. macuUpes Stal on this mountain and 

 on Mount Banahao. Both these species are very variable in the 

 color of the legs, which are sometimes almost entirely fuscous. 



Caracolpura Bredd. (type, C. planiceps Bredd.) , which Breddin 

 regarded as a subgenus of Colpura, seems to me to be generically 

 quite distinct from it by the structure of the head, which is 

 broader than long, quite plane above, and distinctly narrowed 



^ In my supplement to Lethierry and Severin's Catalogue of the Co- 

 reidje I have indicated Xanthocolpura venosa Bredd. as described from 

 Borneo, but its habitat is Balabac Island, about 32 kilometers (about 20 

 miles) south of Palawan, which politically belongs to the Philippines. 



' Since this remark was written Kiritchenko has shown, after exami- 

 nation of specimens of Vittorius adspersus Dist., that Vittorius Dist. is 

 a straight synonym of Colpura Bergr.
