22 AMERICAN COLEOPTERA. 



It is known to rae from southern Wyoming, Colorado Springs 

 and Buena Vista, Colorado, New Mexico, Holbrook, Arizona, and 

 Nevada. A specimen has also been seen labelled "North-west 

 Territories of Canada." 



A. blancliardi n. sp. — Form and color nearly as iu jacobina Lee. Thorax 

 longer in proportion to its width, being about one-half wider than long, more 

 strongly constricted behind and less densely punctured at base and apex, with 

 the basal impressions distinctly bifoveate; side margin narrower; transverse 

 impressions feeble, median line distinct, abbreviated in front; hind angles 

 prominent, rectangular and acutely carinate. Elytra together scarcely wider 

 than the thorax and nearly twice as long as wide, striate; striae entire and dis- 

 tinctly punctate to behind the middle, the eighth with the row of ocellate punc- 

 tures broadly interrupted at middle; intervals flat ; humeri subangulate. Met- 

 episterna impuuctate or with a few sparse punctures. Legs rufous or piceo- 

 rufous; middle and posterior femora with two or three setigerous punctures 

 along the inner margin ; two basal joints of the middle and hind tarsi grooved 

 on the outer side. Length .42-.50 inch ; 10.5-12.5 mm. 



In the above brief description I have indicated the salient points 

 of difference between this species and jacobina, with which it has 

 been confused in collections. The thoracic differences, the grooved 

 basal joints of the middle and hind tarsi and the different number 

 of setigerous punctures of the femora serve to separate it quite 

 readily from the latter species. 



The middle tibise of the males are distinctly bidentate, the upper 

 tooth being much the more prominent and situated about the mid- 

 dle, the lower about midway between it and the apex. 



It is with pleasure that I dedicate this species to my friend Mr. 

 Frederick Blanchard, of Tyngsboro, Mass., as a slight token of 

 regard and of gratitude for assistance and many favors. 



Over twenty-five specimens have been studied. The type, which 

 is a male, is in my own cabinet and is from Provo, Utah. Cotypes 

 are to be found in the Museum of Comparative Zoology, the 

 National Museum, and in the collections of Messrs. Blanchard, 

 Bowditch, Fall, Liebeck and Wickham. 



It occurs in Nebra.ska, Wyoming, Colorado, New Mexico, Utah, 

 Nevada and eastern California. 



4. A.Javobiiiai Lee. — Form moderately elongate, feebly convex, the elytra 

 more or less flattened on the disk. Color piceous or nearly black, the surface 

 shining in the males, finely alutaceous in the females. Head nearly as wide as 

 the thorax at apex ; frontal grooves short, not extending forward on to the epi- 

 tonia; autennte slender, nearly as long as the head and thorax, ferruginous; 

 palpi ferruginous. Prothorax nearly twice as wide as long, subcordate, slightly
