380 Field Museum of Natural History — Zoology, Vol. VII. 



Head distinctly wider than thorax; front with two, large, feeble 

 impressions; vertex with short longitudinal carina. Thorax one- 

 fourth broader than long; sides broadly, moderately dilated at apical 

 third; subapical constriction strong. Elytra bluish black, nearly 

 covering the abdomen; flanks very slightly convergent posteriorly; 

 slightly wider than the head; humeri distinct; coarsely, deeply, very 

 densely and roughly punctate, punctures more or less confluent 

 especially at base; apices obtusely separately rounded, moderately 

 strong]}' serrate; hind femora extending to tip of abdomen. Length 

 4.5-5 millim. 



Closely allied to nigro-CBnea Gorh., but differing from that species 

 by the wider prothorax, much less convex form, coarser elytral punc- 

 tuation, more coarsely, densely punctate head and thorax, and ab- 

 sence of upright black pilosity. 



Cuemavaca, Morelos, Mexico. Five specimens. Type and three 

 of the cotypes in cabinet of Prof. Wickham; one of the cotypes in 

 possession of the author. 



Hydnocera spinolae sp. nov. 



Moderately elongate, black, shining; head and thorax with faint 

 coppery reflections; antennae pale, basal joint and apex of club fus- 

 cous; knees, tarsi, and hind tibiae obscurely testaceous. Head as 

 broad as elytra at base, densely, finely rugulose; front not impressed; 

 a small distinct rounded fovea on occiput; clothed with short, mod- 

 erately dense, ashy, recumbent pubescence and rather sparse, erect, 

 black pile. Thorax slightly narrower than the head, as long as broad, 

 rather finely, irregularly rugosely punctate; sides not very strongly 

 dilated; pubescence grayish, very sparse, black pile longer, coarser, 

 and more dense than on head. Elytra scarcely shorter than the ab- 

 domen, nearly parallel, more strongly convergent behind the middle 

 of their length; humeri distinct; shoulders carinate, the carina 

 short but distinct; disk feebly convex; suture strongly depressed at 

 base; ashy pubescence rather conspicuous especially towards the 

 apices, erect black pile conspicuous at basal third; rather coarsely, 

 somewhat confluently punctate; apical third finely scabrous; apices 

 separately obtusely rounded, very finely, feebly serrate, narrowly 

 dehiscent at suture. Length 4 millim. 



Named in honor of the Marquis Maximilien Spinola, author of the 

 only monograph of the family Cleridae. 



Cuemavaca, Morelos, Mexico. One specimen. Type in cabinet 

 of Prof. Wickham.
