angles obtuse, base slightly rounded, very finely margined. Scutellum 
large, acuminate behind. Elytra nearly four times as long as the pro- 
thorax, but not wider; striz not impressed, strongly punctured ; scutellar 
stria long ; behind the base there is a shallow impression. Antenne paler 
at base, club large, two-jointed ; eyes convex prominent. Length 2.7 mm.; 
-10 inch.

other specimens from Canada and California. 
EURYSPHINDUS noy.gen. SPHINDID. 
General characters as in Sphindus, except : 
Body broadly oval, moderately convex, clothed with erect hairs ; pro- 
thorax narrowed in front, rounded on the sides; elytra with strive feebly 
impressed, strongly punctured. Flanks of prothorax deeply and widely 
concave beneath. Eyes small, frontal suture finely impressed, not deep. 
28. E. hirtus. Blackish brown, shining, pubescent with stiff erect 
hairs. Head sparsely punctulate, frontal suture fine, eyessmall, not promi- 
nent, but convex. Prothorax more than twice as wide as its length, nar- 
rowed in front, sides slightly flattened, edge acute, crenulate, scarcely mar- 
gined, base sub-sinuate not margined, disc strongly not coarsely punctured. 
Scutellum large, finely punctured. Elytra with strive of well marked 
punctures, interspaces feebly convex, rugosely punctulate ; humeral callus 
rather prominent, paler brown. Beneath punctured, tibise and tarsi paler. 
Length 1.6 mm.; .06 inch. 
Detroit;onespecimen. Inthe Munich Catalogue Sphindus is 
placed at the end of the Prinide, a position for which it is unsuit- 
ed, on account of the much smaller coxal cavities the pros- 
ternum distinctly separates the coxse, which are themselves, 
though transverse, small and not prominent. The form of 
the antenne and tarsi also forbids a reference to the 
Ptinide. To these characters I have to mention, that the 
antenne, in repose, are flexed in a different manner, the 
slender part being laid each side along the prosternal suture, 
and the club bent suddenly outwards, behind the front leg. 
In Eurysphindus the flanks of the prothorax are deeply con- 
cave for the reception of these organs, in Sphindus the con- 
cavity is much less; and in Odontosphindus the depression is 
obsolete, though the form of the antennee is the same in all 
three genera. I may here observe that the club of the an- 
tennee is described as three-jointed ; the 8th joint is so much
