Tune, 1913-] ROBERTS: NOTES ON HaLIPLID^ OF AMERICA. 97 



ticulate, interior angles acute ; striae composed of closely placed punctures, 

 fine and shallow towards the suture, coarser and deeper at the middle and 

 sides and which are confused near the base ; sutural interval with a double 

 row of very fine and closely placed punctures and the other intervals with 

 single rows of fine punctures not so closely placed ; maculate with eight small 

 spots on each elytron placed as follows ; one centrally on the base, one sub- 

 humeral, one median and below this one a sublateral, a submedian and a 

 sutural one placed nearly horizontally, the last coalescent with the suture, 

 below these three two more, the one placed near the suture and the other 

 obliquely below near the lateral margin ; the base is very narrowly black from 

 suture to just beyond the basal spot ; the suture narrowly black for its entire 

 length and the apices tipped with black in the usual way at the sutural angle. 

 Under surface of the same color as the upper with an infuscate patch about 

 the front and middle coxas, and the posterior margins of the abdominal seg- 

 ments also infuscate. 



Prosternal process with the sides parallel for nearly their entire length, 

 slightly excurved near the declivity, quite strongly margined laterally and with 

 the apex finely margined ; slightly convex and finely, densely and evenly 

 punctured between the margins. 



Mid-metasternum margined for about two thirds the distance to the suture 

 of the antecoxal piece with a few scattered punctures between the margins. 



Hind coxas evenly punctured with shallow medium-sized punctures, broadly 

 rovmded from exterior angle to suture where the angles are obtuse. 



Male front and middle tarsi with the second and third joints shortened 

 and slightly produced apically ; claws long and slender. 



Male and female types from Albtiquerque, New Mexico (H. F. 

 Wickham) are in my collection. 



Other specimens before me are from Shovel Mt., Texas (F. G. 

 Schaupp), and from "Tex." (U. S. Natl. Mus. Coll.). 



In a dozen or more specimens there is scarcely any variation ex- 

 cept that in some female specimens, the interior stibapical spot is 

 joined to the stiture by a narrow point or line. 



At first I hesitated to describe this species, thinking it might be 

 Mr. Matheson's decepfits; but even taking into account his very 

 vague description there seem to be several decided points of differ- 

 ence. The smallest specimen of suhtralis is not as small as his de- 

 ceptiis; the color is not pale yellow; the spot on pronotum is not 

 rufous: a Carl Zeiss, 27, hand lens shows no denticulation to the 

 apices of elytra, nor is the exterior angle so acute as represented in 

 the cut on his plate of elytra. Siitiiralis has no close relationship to 

 either borcalis or Iczcisii, from which species Mr. Matheson separates
