11. Eyes with a small semicircular emargination; cephalic carinae distant, 
converging to the clypeus but not uniting, thence feebly diverging on 
the front 10. distans 
Eyes deeply triangularly emarginate 12 
12. Cephalic carinae parallel from the occiput to the front, divergent on the 
front 11. pugnax 
Cephalic carinae approximate, converging and confluent in front, thence 
diverging on the front 12. convergens 
Clypeus tuberculate, carinae parallel above 13. nodifrons 
[Aulonothroscus rugosiceps Schaeffer^ was unknown to Mr. Blanchard and I 
have not thought best to modify his table to insert it. It is said by Mr. 
Schaeffer to be related by its entire eyes and long, entire prosternal striae to 
constrictor, from which it differs in the distinctly carinate hind angles of the 
prothorax, the carinate head, and the absence of the basal impressions of the 
prothorax, which are very pronounced in constrictor. Length 4 mm. Browns- 
ville, Texas. H. C. F.] 
1. Aulonothroscus parallelus new species 
Very elongate and parallel, thorax impressed each side at base, but less 
strongly than in teretrius, the dorsum less arched longitudinally than in that 
species. Head and thorax uniformly, finely punctate, thorax as wide as the 
elytra, one and one-half times as wide as long, sides rather parallel at base, 
thence arcuate to apex. Elytra with rather fine striae, with subelongate punct- 
ures but little larger than those of the intervals, these rather finer than the 
thoracic ones and with the usual arrangement, although rather more distant 
than in the next species. Prosternum with striae more strongly divergent, 
reaching the anterior third or fourth, somewhat convex and punctate more 
closely in front, more broadly convex in front, punctures of flanks, sides of 
metasternum and abdomen similar and much as in the next. Length 3.5 to 
3.7 mm. 
One more slender specimen has the antennal club a little 
broader and is, I presume, a male. There is no trace of long hairs 
on the metasternum. This is the most elongate species seen 
and could only be confused with the following, which it closely 
resembles in punctuation, although punctures are rather finer 
and sparser. The much more elongate form, less arched dor- 
sum and less impressed base of thorax will distinguish it. The 
prosternum also is broader and more convex anteriorly, and the 
striae more divergent. 
Virginia — one specimen (Mr. Liebeck) ; three in the Zimmer- 
man Collection at Cambridge, without locality but undoubtedly 
southern.
