H. strigicollis n. s]). — Moderately elongate, pjceous, feebly shining, legs 

 and coxee ferruginous. Antennee very little longer than the head and thorax, 

 brownish, outer joints slightly broader. Head coarsely and densely punctured in 

 front, longitudinally deeply strigose posteriorly. Thorax one-half wider than 

 long, apex and base equal, sides feebly arcuate, apical and basal angles obtuse, 

 surface deeply longitudinally strigose. Elytra oblong oval, not wider than the 

 thorax, sides feebly arcuate, surface moderately deeply striate, striae punctate, in- 

 tervals slightly convex, slightly wrinkled, irregularly biseriately punctulate, these 

 small punctures with fine inconspicuous hairs. Prothorax beneath coarsely punc- 

 tured at middle, longitudinally strigose at the sides. Body beneath coarsely punc- 

 tate. Abdomen less coarsely punctate and more shining. Femora sparsely punc- 

 tate, the tibise more densely. Body apterous. Length .31-. 42 inch; 8-10.5 mm. 



This species has the thorax as wide as any portion of the elytra, and 

 is unique in our fauna in the sculpture of its upper surface. It is related 

 to Bachei and rugicollis^ and should be placed between them. 



'Three specimens from the southern part of California, probably near 

 San Diego.

O. betulcti n. sp. — Black, subopaque, abdomen and elytra clear red, t4.rsi 

 and antennae pale yellow. Rostrum coarsely punctured, smoother and vaguely 

 bisulcate in front, head coarsely and deeply punctured, very sparsely pubescent. 

 Thorax wider than long, much narrower in front, sides arcuate, median line finely 

 impressed, surface coarsely and deeply punctate, very sparsely pubescent. Scu- 

 tellum black. Elytra oval, one-third longer than wide, striate, stride coarsely and 

 closely punctured, intervals scarcely wider than the strise, flat, irregularly biseri- 

 ately punctulate, surface shining, very sparsely indistinctly pubescent. Body 

 beneath black, coarsely punctate, more distincth' pubescent than above. Abdo- 

 men entirely red, obsoletely punctate. Legs black, coarsely punctured, posterior 

 femora stouter than the middle and with two dentiform tubercles at middle be- 

 neath. Antennse pale yellow, the club fuscous, funiculus six-jointed. Length 

 .11 inch ; .3 mm. nearly. 



Among the few species in our fauna this is readily distinguished by 

 its color. There are several species in Europe similarly colored, from all 

 of which it seems to differ. 



Three specimens, Washington, D. C, given me by Mr. E. A. Schwarz, 

 collected on Betula nigra.
