selected from a series of about three dozen specimens of con- 
strictor from the same locality, two of them bearing the same 
date — June 7, 1900, the rest, IVIay 14 to 30 of the same year; the 
male. May 19, 1891. The prosternal striae are rather more abbre- 
viated in the male, and as much so as in many punctatus. A sec- 
ond female from “N. Y.” (Chas. Fuchs Coll.) I am inclined to 
place here also; in it the prosternal striae are longer as in the 
male, the punctuation triple on the third interval and double on 
the first to the middle. In the Virginia examples the punctures 
are double only a very short distance at the base of the first 
interval. 
Bonvouloir described and figured this species, giving also a 
fairly characteristic figure of the antennae in the short paper 
which appeared shortly after his monograph. As may be in- 
ferred it is very different — especially in the male — from con- 
strictor, of which it was made a synonym by Dr. Horn, who prob- 
ably had not seen a specimen. 
8. Aulonothroscus constrictor Say 
Oblong, robust, narrowed behind, brownish piceous or with the elytra rufo- 
piceous in the male; rather coarsely hairy, integuments shining. Head con- 
vex, finely, not closely punctate, clypeus wdth side margin limiting antennal 
foveae more or less evident; eyes small, scarcely larger in the male, feebly 
nicked at insertion of antennae. Antennae with club very similar in the sexes, 
slightly asymmetric, the tenth joint transverse, the last joint smaller in the 
female. Thorax convex, strongly bi-impressed at base, sides arcuate in the 
female; slightly dilated at base, parallel and then oblique in the male; margin 
two-thirds to three-quarters of the length, carina of hind angles feeble or 
wanting, rather coarsely and uniformly punctate in the female, more finely in 
the male. Elytra twice as long as wide, distinctly narrowed behind, obliquely 
impressed behind the humeri, more strongly in the male, striae well defined, 
with closely placed elongate punctures, not coarser at apex, intervals with 
the usual irregular punctuation reaching on the disk to or behind the middle, 
thence uniseriate; in the female sometimes irregular and double to the tip on 
the fifth interval, the punctures nearly as large as those of the pronotum; 
outer intervals more finely and sparsely punctate, six to eight mostly uniseriate 
except at immediate base, the ninth interval in the female showing a double 
series of fine punctures its wdiole length, these being so fine in the male as 
to be observed with difficulty. Prosternum rather wide, sparsely punctate, 
striae usually nearly entire, sometimes, especially in the female, shorter, but 
the margin itself reaching very nearly to the apex. Flanks of prothorax and 
sides of metasternum and abdomen rather coarsely and closely punctate, 
metasternum at middle much more finely and sparseb' so. Length 2 to 
3.3 mm.
