484 TERTIARY INSECTS OF J^ORTH AMERICA. 



molitor (Linn.), the beetle of the common meal-worm. It has been flattened 

 by pressure, so as to show but little sign of having been arched, while at the 

 same time the shape is fairly preserved. Wherever it differs in color from 

 the stone it is piceous. The margins are very nearly parallel, approaching 

 each other rather gradually and very regularly toward the tip ; there are 

 eight equidistant, pretty strongly impressed, rather coarse, longitudinal 

 striae, besides ochers next the outer margin, whose number can not be deter- 

 mined, and a short scutellar stria, about as long as in T. molitor, but quite 

 as distinct as the others ; the surface between the striae appears to be very 

 minutely subrugulose, and shows in favorable light a faint transverse cor- 

 rugation. 



Length of elytron, ll mm ; breadth, 4.4 mm . 



Nine-mile Creek, British Columbia. One specimen, No. 63 (Dr. G. M. 

 Dawson).

The single specimen consists of two elytra, in natural juxtaposition 

 seen from above. They have a brown color, which is wanting in certain 

 places, but in so irregular a manner that it is doubtless fortuitous ; they are 

 furnished with striae, but these, as well as all color, are entirely obliterated 

 in the middle of the wing ; this again is doubtless a defect of preservation, 

 since the sutural edges of the elytra are similarly affected ; the striae are 

 deep, sharply cut, straight, subequidistant, eight in number, fading out at 

 the apex of the elytra, the space between them smooth and arched. 



Length of one elytron, 5 mm ; breadth of same, 1.9 mm ; distance of striae 

 apart, 0.45 mm . 



Chagrin Valley, White River, Colorado. One specimen (W. Denton).
