170 MEMOIRS ON THE COLEOPTERA 



this species from cardinalis; it almost exactly resembles rufipennis 

 in general form and size, but the eighth antennal joint is broader, 

 more nearly as in clavicornis, of which I have a good series from 

 Honduras and Panama. 



*./Egithus abruptus n. sp. Rather elongate-oval, convex, very dull in 

 lustre, pale piceous-brown throughout the body and legs, rather paler 

 beneath, the last five or six antennal joints black; head rather more than 

 two-fifths as wide as the prothorax, flat above, with some minute sparse 

 punctulation, a little stronger on the epistoma; at each side just above 

 the antenna there is a pronounced ridge, which is prolonged posteriorly 

 above the eyes in a very fine line, the eyes well developed and prominent; 

 antennae fully as long as the head and prothorax, with a broad 4-jointed 

 club, the seventh joint black and intermediate in thickness between the 

 sixth and eighth, the sixth only piceous though much darker than the 

 preceding joints, the third nearly as long as the next two; prothorax two 

 and one-half times as wide as its median length, the sides very strongly 

 converging, the apex deeply sinuate, all the edges finely margined, the 

 basal lobe broadly rounded but pronounced; surface impunctate and very 

 feebly but evenly convex throughout the width; scutellum nearly as long 

 as wide, obtusely ogival; elytra at base abruptly wider than the thoracic 

 base, not quite one-half longer than wide, widest before the middle but 

 with very evenly arcuate sides from base to the obtusely ogival apex; 

 surface of each with three double series of distinct punctures, a subsutural 

 series and, near the sides, a very confused series, all the double series 

 vanishing at a considerable distance from the apex and the third gradually 

 obsolescent basally; the general surface has also some minute sparse 

 punctulation; under surface almost punctureless, the abdomen sparsely 

 puberulent and with very minute sparse punctulation. Length 7.2 mm.; 

 width 4.4 mm. Mexico (Rio Balsas, Guerrero),- Wickham. 



This species is allied closely to hogei Gorh., also from Guerrero, 

 but the author states of hogei that "only the two inner pairs of striae 

 are visible, and they are very faint and almost obliterated, except 

 in the middle." This language will not apply even approximately 

 to abruptus, and I infer, therefore, that the two are distinct, either 

 specifically or subspecifically. 



Lybas Lac. 



The following species is remarkable in coloration, in its varnish- 

 like lustre and almost punctureless elytra and does not agree with 

 any of the published descriptions: 



*Lybas cruentissimus n. sp. -Broadly, evenly oval and very strongly 

 convex, highly polished and deep yellowish-red throughout the body and 

 legs, rather paler in tint below than above, glabrous, excepting the tibiae,
