156 JOHN L. LECONTE, M. D. 



One specimen from Virginia, given me by INIr. E. T. Cresson. With 

 the exception of C. hispid idus, piiberuhis and Crypturgus atomus, this 

 is the smallest native Scolytide known to me. The elytra under a high 

 magnifying power show some very faint rows of small punctures.

California. 



14. C. pilosulus. — -Elongate, eylindrioal, yellow ferruginous, shining, front 

 hairy; prothorax longer than wide, finely asperate in front, tolerably densely 

 punctured behind, uniformly clothed with fine pubescence; elytra tolerably 

 densely and finely punctured, and clothed with fine erect hairs, without any 

 appearance of stria3, obliquely declivous and slightly flattened behind. Long. 

 2 myi. 



I found one specimen of this species in middle California; others 

 were collected by Dr. Horn in the southwestern part of the State. 



15. C. hispidulus. — Moderately elongate, black, scape and first joint of funi- 

 culus of antennte, tibiaj and tarsi ferruginous; head prominent convex, finely 

 reticulate ; prothorax not longer than wide, convex, before the middle rough with 

 acute reclinate tubercles, rugosely punctured behind, clothed with short stilf 

 hairs ; elytra with approximate rows of quadrate jjunctures, intervals narrow, 

 with rows of close set short stiff erect gray bristles ; posterior declivity rounded, 

 not at all flattened. Long. 1 — 1-5 mm. 



District of Columbia, Georgia, Louisiana ; this species, though evi- 

 dently related to C. dissimilinj has the outer portion of the funiculus, 

 or rather the pedicel of the club of the antennae, slender and divided 

 by very fine transverse sutures, the base of the club is shining and 

 smooth. 



16. C. striatus. — Elongate cylindrical, dark brown, antennae and feet yellow; 

 head prominent, convex, punctured, slightly pubescent, with a smooth trans- 

 verse frontal elevation; prothorax longer than wide, convex, finely roughened 

 in front, with a few larger tubercles, which are somewhat acute, tolerably 

 densely and coarsely punctured behind, sparsely clothed with short hairs ; 

 elytra with approximate rows of large quadrate punctures, intervals each with 

 a series of very fine punctures bearing short yellowish hairs; tip obliquely 

 declivous, very slightly flattened. Long. 2 mm. 



This species is widely distributed. I have several specimens col- 

 lected at Cape San Lucas, Lower California, by Mr. John Xantus, 

 others were found in Middle California by Dr. Horn, and I have seen 

 two in the collection of the American Entomological Society which 

 came from Hlinois. The club of the antennae is very distinctly annu- 

 lated, the outer part of the funiculus is divided by one transverse 

 suture, visible only under a compound microscope; it is therefore only 

 3-jointed; the first joint is larger than the other two united. 



20. C. atratulus. — Elongate cylindrical, black, antennae and feet very dark 

 brown; front clothed with long hair ;'prothorax longer than wide, sides nearly 

 straight and parallel, disc rough with elevated tubercles in front, strongly but
