white band at the base as in the allied species, which, showing through the 

 closed elytra indicates the markings found on the elytra of cinereus. Face 

 obviously longer and more convex than in cinereus with the basal middle 

 depressed, and the clypeus and lorae together larger, the former much 

 broader, more convex and more decurved and rounded at apex. 



Described from three females taken by me at Effingham, 

 Kansas, in July, 1900. 



17. Cyrtolobus cinereus Emmons. 



Larger than van with the dorsum less elevated and the 

 elytra maculated. Female : color cinerous tinged more or less 

 with ferruginous, especially on the metopidium; anterior oblique 

 vitta broad, indeterminate before, sharply distinguished behind 

 by a narrow brown or fuscous line ; median dorsal spot squarish 

 or longitudinal placed close up to the angle of the dark oblique 

 line; posterior transverse vitta frequently obsolete. Elytra 

 ferruginous and punctured at base ; this is followed by a whitish 

 spot over the pale band on the -base of the tergum, and con- 

 tinuing the broad pale anterior vitta of the pronotum; beyond 

 this is a broad triangular fuscous cloud, the apical one third 

 hyaline with a fuscous cloud at apex covering the terminal 

 areole. Beneath pale marked more or less with black. Face 

 about as in van with the clypeus a little narrower and more 

 produced. What I take to be the male of this species is nearly 

 black with the characteristic markings more distinct, the anter- 

 ior vitta bent over and following the humeral margin. 



This is a broad coarsely punctured species recalling Ophi 

 derma. The female has a peculiar cinerous look with the an- 

 terior brown and grey vitta placed well back and forming an 

 obtuse angle on the dorsal line, but the maculated elytra are 

 perhaps the best character for distinguishing the species. The 

 only specimens I have seen have been from New York. 



18. Cyrtolobus fuscipennis n. sp. 



Closely allied to cinereus but with the elytra almost uni- 

 formly infuscated and the clypeus more produced and less de- 

 curved. 



Color pale ferruginous varied with greyish testaceous, mottled with 

 lighter in a broad band over the metopidium and along the oblique pale 

 vitta. This oblique vitta more distinct than in cinereus, of nearly uniform 

 width, strongly angled just before reaching the median dorsal spot, and
