AMERICAN COLEOPTERA. 193 



and the elytra with three bands of spots more or less developed, and some- 

 times confluent. 



5. — Varies like the % . 



California (Mountains) and Nevada. Very nearly related to II. 

 aureola Pallas, of Northern Asia, and differs chiefly by the head 

 being not covered with scales. I have adopted the MS. name of 

 Mr. Crotch, under which it has been largely distributed. 



.3. H. hirta. — Black, without scales; head, prothorax and metastcrnum 

 clothed with very long fine whitish hairs, the rest of the body clothed with 

 shorter, less fine pubescence. Head densely punctured, epistome sJiort, strongly 

 margined, sides nearly parallel, front truncate and feebly emarginate, angles 

 much rounded. Prothorax scarcely wider than long, slightly narrowed from 

 the base to the middle, then more strongly narrowed to the apex which is 

 broadly emarginate; front angles acute, hind angles slightly rounded, base 

 oblique each side; surface rather densely punctured. Elytra punctured, thinly 

 pubescent as usual. Pygidium densely but not deeply punctured, pruinose with 

 pale hairs. Beneath densely j3unctured. Legs as in the preceding species, but 

 the outer claw of front and middle tarsi is a little shorter. Length 7.5 mm. 



Nevada; one % kindly given me by Dr. Horn. 



12. H. eqmina.— Elongate, brown, not densely clothed with small oval 

 ochrcous sc-iles, permitting the ground color to be quite apparent. Head densely 

 punctured, moderately jjubescent, epistome with oblique rounded sides, front 

 broadly truncate, strongly margined, angles much rounded. Prothorax thinly 

 pubescent with very short hairs; sides subsinuate behind, oblique and strongly 

 narrowed in front of the middle; ajsex strongly emarginate, front angles acute, 

 base oblique each side, angles rectangular, slightly rounded. Elytra with 

 shallow j)unctures as usual. Beneath thinly clothed with scales as above, 

 scarcely pubescent, outer claw of front and middle tibise entirely wanting. 

 Length 7 mm. 



Tyngsborough, Mass. I am greatly indebted to Mr. Frederick 

 Blanchard for a pair of this species, of which he found but three 

 individuals. It is a most interesting addition to our fauna, and is 

 especially remarkable for the strong resemblance which it bears to 

 H. modesta, from which it differs not only by the absence of the 

 smaller tarsal claw, but by the uniform shape of the scales, the less 

 pubescent prothorax and the slightly sinuate sides; this last character 

 is more obvious in the 9 than in the % . 



The following synonymy is proposed, after a careful revision of the 

 materials in the collections of Dr. Horn and myself.
