Hydnocera fuchsi, new species. 



Form of subcenea, black, thorax subseneous, elytra blue, with a transverse 

 median fascia of whitish hairs, apex of front and middle tibiae, tarsi and antennae 

 pale. Head very densely and subconfluently punctured ; eyes prominent. Thorax 

 slightly wider than long, sides broadly dilated a little below the apex, towards base 

 nearly parallel, basal transverse line strongly impressed, subapical impressed line fine 

 but rather strongly impressed ; surface rather densely but not very coarsely punctate, 

 moderately densely pubescent, with recumbent, short, pale hairs intermixed with 

 some longer darker hair ; disk at basal half with an almost smooth narrow space 

 Elytra covering the abdomen, scarcely wider than the head, sides nearly parallel, 

 apices separately rounded and rather strongly serrate ; surface coarsely and moder- 

 ately densely punctate in nearly the whole basal half; apical part below the fascia 

 more densely and cribrately punctured ; pubescence rather inconspicuous, fine and 

 short, the hairs denser and longer in a narrow transverse space about middle. 

 Under side rather sparsely pubescent, except the metasternal side pieces, which are 

 more densely clothed with longer white hairs. Length 5.5 mm. 



Nogales, Arizona, collected by F. W. Nunnenmacher and given me 

 by Mr. Chas. Fuchs. 



Judging from the description, this species seems to be very near 

 the lately described wickhami Wolcott, which has the elytra much wider 

 than the head, shorter than the abdomen, and the apices not serrate. 



Hydnocera arizonica, new species. 



Very similar in sculpture, color and markings to pallipennis, from 

 which it differs in the longer, parallel elytra, always covering the 

 abdomen, the obliquely rounded sides at apex and the non-serrate 

 apices of elytra. Length 4.5 mm. 



Huachuca Mts., Arizona. 



In the two type specimens, male and female, the median band is 

 rather narrow, with irregular outline, and the legs are pale. These 

 are, however, variable ; the legs are in some specimens infuscate and 

 the median dark band is broader and extends at sides nearly to the 

 humeri. The dark markings on elytra are distinctly greenish. 



This species and niveifascia occurred commonly on oak in July 

 and August. 



Hydnocera cribripennis Fall, Canad. Ent., Vol. XXXVIII, p. 116. 



I refer a few specimens from the Huachuca Mts., Arizona, to this 

 species which was described from Fedor, Texas. They differ slightly 

 from the description but not sufficiently to give them a name. The 

 subbasal fascia in these specimens is reduced to a transverse spot which 

 is in one male narrowly connected with the yellow spot seen on the
