obliquely backward to a little beyond the middle near inner third, 

 yellowish-white ; under surface piceous, the abdomen rather closely and 

 strongly though finely punctate. Length, 1.4 mm.; width, i.i mm. Utah 

 (St. George), Wickham. 



This is a wholly isolated species, somewhat remindful at first of the 

 genus Hyperaspidhis ; it may be placed just before annexa in the list but 

 has no affinity with that species. The tarsal claws are obtusely swollen 

 internally at base. 



H. tetraneura, n. sp. — Nearly as in 4-vitiata, tliough very slightly 

 more broadly oval and decidedly less convex, similarly rather strongly 

 and closely punctate, black, polished ; head black; pronotum ( 5 ?) black, 

 with a very narrow, not very abruptly pale side margin ; elytra with 

 the side margin evenly and very narrowly pale to but little beyond two- 

 thirds, each also with a similarly narrow even pale oblique vitta from basal 

 sixth, slightly beyond the median line, to apical fifth at inner third. 

 Length, 2.3 mm ; width, 1.45 mm. Colorado (Boulder Co.). 



Resembles 4-vittata, but differs in the abruptly abbreviated and much 

 narrower vittae, more finely and sparsely punctate abdomen, and, espe- 

 cially, in the much more narrowly rounded post-coxal arcs, which scarcely 

 attain the first suture, along which they are contiguous for some distance 

 in 4-vittaia, 



The species described by Mr. Schaeffer (1. c, p. 143) as Hyper aspis 

 ti'ifurcata. is strongly remindful, in its form and general scheme of 

 ornamentation, of a species published by me under the name Hyperas- 

 pidhis insigiiis^ and I would therefore advise a closer scrutiny of its generic 

 characters. Tne species, though, is doubtless diff:;rent. 



Hyperaspidius, Cr. 



The species described by LeConte under the name vittigera is not 

 by any means the same as the Mexican trimaculatus, Linn., as becomes 

 apparent at once on reading Mulsant's description of the latter. The 

 species should therefore be known under LeConte's name, vittigera 

 { = tri?fiaailatus, Cr,, nee Linn.). 



H, pallescens, n. sp. — Broadly oblong, very obtuse at apex, moderately 

 convex, polished; head and pronotum ( 9 ) rufo-testaceous, the latter subim- 

 punctate, with a narrow yellowish-white side margin ; elytra rather finely 

 and sparsely but strongly and evenly punctate, smooth, pale reddish- 

 brown, the basal and lateral margins, retreating from the edge posteriorly, 

 and not quite attaining the suture at apex, whitish, the basal stripe 

 prolonged posteriorly, near the suture, touching or feebly joining the apex
