186 THE CANADIAN ENTOMOlXXilST 



by a sLibacLite arcuate ridge connecting the second and third 

 teeth; with a small denticle on the end of the fifth interspace at 

 the Ipase of the second tooth; the apical margin of the declivity 

 narrowly separated from the elytral margin, moderately acute, 

 entire, extending across the suture. 



The female has the front closely coarsely granulate-punctate, 

 •with a narrow median carina on the caudal half de\eloped into a 

 compressed tubercle at the cephalic end on the centre of the front, 

 and with a deep transverse impression between the tubercle and 

 the margin of the epistoma; the declivity nearly vertical, similar 

 to that of the male, but much less deeply concave; the sutural, 

 stria" still distinctly but much less deeply and broadly sulcate, 

 and the sides of the declivity less elevated and less distinctly margin- 

 ed; the apical margin feeble, barely distinct at the suture; with 

 smaller teeth, situated much as in the male, on the convexity 

 laterad of the sulcus, but in a straight olilicjue line, the first minute, 

 the second and third alike, small, conical and acute; the concavity 

 densely, coarsely punctured and hairy as in the, male. The second 

 visible segment of the abdomen is as long as the next two united. 



This species unites the characters of Orthotoynicus with those 

 .of Pityokteines. It is allied to Orlhotomicus in the frontal secondary 

 sexual characters, and in the fairly distinct apical margin of the 

 declivity; but rather closely to the typical Pilyokleines in the 

 small size, long second visible abdominal sternite, and frequently 

 by the characters of the somewhat variable antennal club. 



It is represented in our collection as follows: A short type 

 -series from Williams, Arizona, in the Cornell I'ni. Collection, 

 No. 302, sub. 100; a short series from Oregon sent by Professor 

 H. F. Wilson; a short series from Tulare, Co. Cal., taken by Mr. 

 Ralph Hojiping in Finns ponderosa and Finns jeifreyi. The type 

 is in the collection of the Kntomological Branch, Ottawa.
