THE CANADIAN ENTOMOLOGIST. 117 



head, much less ihan twice as long as wide, sidej plainly convergent 

 posteriorly, apices separately rounded and serrulate, surface very densely, 

 coarsely punctate, becoming strongly cribrate toward the apex. The 

 pubescence is somewhat condensed, and transversely inclined on the 

 posterior pale spot. Legs rufotestaceous, the thighs all more or less 

 infuscate. 



Length, 3.5 mm. 



Fedor, Texas. One male. 



A specimen in the LeConte cabinet bears the manuscript name, 

 granipefinis, which I have changed to the more appropriate one here 

 given. The sculpture of the elytra is rougher than in any other species 

 known to me, but is nearly approached by Kiiausii^ which, however, 

 differs much in its coloration, more slender form, less densely punctured 

 thorax and sparser vestiture. 



Hydnocera affiliata^ n. sp. — Similar in form and colour io pallipetinis, 

 to which it is very closely related, differing only as follows : Head and 

 prothorax closely punctate and feebly shining (sparsely punctaie and 

 shining in /^////^//;//V), elytral punctures a little closer, the apex always 

 pale, and usually with a small antiapical black spot. 



California (Pasadsna and Pomona). 



Hydnocera sobrina, n. sp. — Slender, shining, black, with faint aeneous 

 tinge, front and middle legs pale, hind legs black, the knees and tarsi ]^ale; 

 pubescence sparse, erect, uniformly distributed, ochreo-cinereous. Head 

 finely but distinctly, not closely punctate, eyes not very prominent ; 

 antennae pale, the tip of the terminal joint darker. Prothorax fully as long 

 as wide, anterior dilatation not very strong, much as in verlicalis, apical 

 constriction moderate, sides parallel behind, lateral foveie feeble ; surface 

 rather sparsely and finely punctate, median line faintly elevated for a short 

 distance behind the anterior constriction. Elytra parallel, much shorter 

 than the abdomen, dehiscent at apex, the tips rounded and feebly serrate, 

 punctuation moderately strong and close, but much finer than in verticalis. 



Length, 4 mm. 



Oak Creek Canon, Arizona, July (Snow). 



This is a rather inconspicuous species, which is in general form 

 related to verticalis, but seems quite distinct from any of our described 

 species.
