304 MEMOIRS ON THE COLEOPTERA 



rapidly cuneiform, though in prcecellens Bates, they are as strongly 

 trigonal and almost as convex as in any of that genus. Besides 

 a good series of araneiformis and one each of longipennis and 

 prcBcellens Bates, I have in my collection two other species, which 

 are not identifiable with any of those recorded by Bates; these 

 are the following: 



*Lagochirus parvulus n. sp. Form much more parallel than in ara- 

 neiformis and very much smaller in size, though almost similarly marked, 

 the lateral elytral dark spot similar but more sinuate antero-internally, 

 black, densely clothed throughout with pale brown vestiture, variegated 

 but slightly, excepting the lateral dark area and a very few extremely 

 faint posterior transversely wavy lines on the elytra; head dark, the 

 sculpture concealed; antennae (cf ) very slender, unusually short, two- 

 thirds longer than the body, evenly and densely ochreo-pubescent through- 

 out, without trace of annulation and with the node of the sixth joint 

 obsolete, represented by a glabrous convex spot; prothorax small, nearly 

 twice as wide as long, nearly as in araneiformis, the elytra also similar, 

 except that they are parallel, the punctures still more obsolescent api- 

 cally; last dorsal segment much more narrowly rounded; legs shorter, the 

 femora much more feebly clavate, the tarsi more slender, the anterior 

 but slightly dilated and with short cilia; last ventral segment broadly, 

 almost rectilinearly truncate. Length (cf) n.o mm.; width 4.6 mm. 

 Panama (Nata). 



Resembles very much an extremely small example of aranei- 

 formis, but parallel and with relative smaller prothorax and truncate, 

 not broadly sinuate, apex of the fifth ventral segment. 



*Lagochirus procerus n. sp. Form narrower and more elongate than 

 araneiformis, blackish, densely clothed with very short whitish tomentum, 

 the dark lateral spot of the elytra as in araneiformis but with much 

 more extended white area behind the spot and between it and the 

 distinct entire transverse dark fascia at apical fourth, which shades 

 off gradually paler posteriorly and with its sharply marked anterior 

 margin biangularly reentrant; punctures sparse; fasciculi and granose 

 basal ridges as in araneiformis; head similar, the antennae (cf ) slightly 

 more slender and not uniformly clothed but with joints 1-3 finely mottled, 

 4-6 biannulate with cinereous, the node and erect seta similar on the sixth, 

 the remaining joints with dense cinereous-white pubescence, solid on the 

 outer joints, darker at base and apex on the seventh, diminishing on the 

 following; prothorax similar but smaller; elytra more elongate, moderately 

 cuneiform, three-fourths longer than wide; fifth ventral a little longer, 

 more strongly rounded, with the median sinus narrower and very distinct; 

 last dorsal broad, sinuate at apex, with rounded angles. Length (cf) 

 20. o mm.; width 8.5 mm. Unlabeled, but probably from Lower Cali- 

 fornia.
