Trigonops coendescens Blanch. near apex, lateral margins elevated; center of disc flat, with slight elevation toward apex; sur- face rough due to small tubercles and punctures; stripes of blue scales border the median area. Elytra widest near base; tapering to a slender apex; elevated near declivity along 5-6 striae, central part of disc flat or slightly cupped; punc- tures deep covered with scales, intervals promi- nent, declivity abrupt. Legs, femora large, scales sparse, color reddish-brown, not reaching end of elytra, underside of body with blue scales, except ventrites 3-5; ventrite 5 with wliite setae. Length mm; breadth mm. Type locality: Solomon Islands: Saint George Island, 1941 (H. Guerin). Specimens available for this study: Guadalcanal Island: -3 specimens from Wanderers Bay (Woodford). Two speci- mens in the British Museum of Natural History, London, England. One specimen in the Brigham Young University Entomological Collection. T. coerulescens may be readily recognized due to the following characteristics: the conical elevation at apex of rostral carina; wide pro- thorax; elytra with lateral elevations and cupped center, abrupt apical emargination, and its size. This species resembles carinithorax in the shape of the prothorax and elytra. The eyes, sulcus of rostrum, antennae, scale color and shape are different. Trigonops marshalli n. sp. Fig. 28 Body derm black, clothed blue and green scales. Rostrum as broad as long, as long as head, carina short, narrow, and tumid at base, with a small elevation at declivity which bears a few small scales; sulcus crescent-shaped with a fovea at apex of head; scrobes deep and open. Anten- nae scape slender, enlarged a little at apex, seg- ments 1-3 of funicle elongate and equal, seg- ments 4-7 obpyriform, club as long as 5-7 com- bined. Head punctate with waved lines converg- ing
