scales. The rows of elytral punctures are well separated. The an- 

 terior tibiae have a small spiniform tooth. Only females have been 

 seen, the last ventral without fovea and obtuse. 

 Occurs in Montana, Kansas and Nebraska. 



GL.YI»TOSCEL,IS Lee. 



The species of this genus are all of rather large size for this tribe 

 as represented in our fauna. They are all more or less densely 

 clothed with hairs, scaly hairs or scales, always recumbent. It will 

 doubtless have been ob.served that the species in our fauna constitute 

 two dissimilar series, the one series longer with vestiture as above, 

 the other smaller with short, sparse, erect hairs. Crotch remarked 

 that tliese resemble (Heteraspis) Graphops. In truth, they should 

 be separated from Glyptoscelis by the form of the prosternum, the 

 latter having a narrower prosternum, while in the three small species 

 the prosternum is broad and subquadrangular. 



The species of Glyptosce/is are thus distinguished: 



Claws cleft, but sometimes feebly 2. 



Claws absolutely simple 6. 



2. — Vestiture of surface hair-like. 3. 



Vestiture scale-like 6-squainiilata. 



3. — Elytra with distiuct circum-scutellar depression 4. 



Elytra convex at base 5. 



4. — Vestiture of elytra sparse, but equal 2-|>ubesceiis. 



Vestiture in broken lines 1-illustris. 



5. — Thorax slightly narrowed at base; punctuation of elytra conspicuously 



coarse, vestiture feiTuginous 3-biirbatsi. 



Thorax not narrowed at base. 



Pubescence white and uniform 5-albida. 



Pubescence forming vittse alternately darker 4'altei'iiata. 



6. — Elytra acute at tip and slightly prolonged ; vestiture of scale-like hairs. 



7-cryptica. 



G. illustris Cr., Proc. Acad. 1873, p. 35. — Median line of front distinctly 

 impressed. Thorax wider than long, narrower at base than at middle. Elytra 

 not densely punctate, pubescence sparse, and in great part short and brown, 

 with slightly longer whitish hair along the side margin and sutui-e and forming 

 several short lines on the declivity. Length .35 — .40 inch. ; 9 — 10 mm. 



Some well preserved specimens in the collection of the National 

 Museum are by no means so greatly deprived of pubescence on the 

 elytra as those in ray cabinet, the types of Crotch. In mine there 

 are large nude spaces, while in those the entire surface is sparsely 

 clothed with a white pubescence easily removable by abrasion. 



Occurs in Oregon and northern California.
