THE CANADIAN ENTOMOLOGIST. 231 



Hydnocera Wickhami^ n. sp. — Large, robust, moderately depressed, 

 black, slightly bronzed, above subopaque, body beneath and abdomen 

 moderately shhiing, head and thorax with greenish reflections. Head 

 scarcely wider than the thorax, eyes large, ciliate, with long dark hairs, 

 moderately prominent, labrum and labial palpi black, antennae and 

 maxillary palpi (except apical joint of latter) pale testaceous, antennae 

 moderately slender, extending nearly to middle of thorax, mass obtuse at 

 apex, head very densely but not very coarsely rugose, frontal impressions 

 very feeble, with a few semirecumbent short silvery white hairs, and longer 

 erect grayish and black hairs. Thorax broader than long, apical 

 constriction strong, sides broadly, not very strongly, dilated, posteriorly 

 arcuately narrowing to base, apical transverse impression nearly obsolete, 

 basal margin reflexed, a short, deep, transverse, submarginal impression 

 at middle of base, disc with longitudinal nearly smooth space, elsewhere 

 densely, coarsely rugose, lateral foveas feeble, clothed in same manner as 

 the head. Scutellum clothed with fine, rather sparse, short, whitish 

 pubescence. Elytra much wider than the head, humeri obtusely rounded, 

 sides straight, parallel, slightly shorter than the abdomen, apices obtusely, 

 separately rounded, not serrate (merely a little irregular in outline), 

 slightly dehiscent at suture, the pubescence forming a fascia behind the 

 middle in which the silvery-white recumbent hairs are directed both 

 posteriorly and laterally, remainder of surface with very sparse short white 

 hairs and longer erect black hairs, the whitish hairs being most conspicuous 

 at the humeri and apex, before the postmedian fascia coarsely, deeply but 

 moderately sparsely punctate (the individual punctures well separated), 

 behind the fascia the punctuation is coarse, less deep and more crowded, 

 elytra not more strongly depressed toward the apices, which are not at all 

 tumid. Body beneath and abdomen sparsely pubescent with long whitish 

 hairs, abdomen rather coarsely, moderately sparsely punctate, posterior 

 margins of ventral segments four and five broadly testaceous. Legs black, 

 anterior tarsi and apex of tibiae testaceous. Length, 6 mm. 



Santa Rita Mts., Arizona. One specimen collected and sent to me 

 by H. F. Wickham. 



Only one other species of Hydnocera known to me exceeds this in 

 length. H. /onga, which is one millimeter longer, is of an entirely different 

 form, the thorax being as long as broad, and the legs are also much more 

 elongate.
