small, separated from one another by about twice their own widths ; 

 interstrial spaces on sutural regions flat, about three times as wide 

 as the strial punctures, wider and more convex toward sides, sparsely, 

 finely, regularly punctate, with a long, fine, erect, brownish hair aris- 

 ing from each puncture. 



Abdomen beneath finely, sparsely punctate on basal sternites, 

 sparsely, coarsely punctate on apical sternites, sparsely clothed with 

 long, fine, erect and recumbent, white hairs; intervals smooth; last 

 visible sternite broadly rounded at apex, with an irregular, short 

 subapical carina at apex. Prosternum sparsely, coarsely, deeply 

 punctate at middle, coarsely ocellate-punctate at sides, sparsely 

 clothed with long, fine, recumbent, white hairs; anterior margin 

 emarginate, with two vaguely indicated, indistinct lobes near the 

 middle. 



Length 9-10 mm,, width 3.5-4 mm. 



Type locality. — Oaxaca, Mexico. 



Type andparatype.—V.S.^M., No. 58793. 



Described from two specimens (one type) from the Wickham 

 Collection collected September 1894, at an altitude of 5,000 feet. 



This species belongs to Horn's Sinuatae group. It is allied to Ac- 

 maeodera serena Fall, but it differs from that species in being uni- 

 formly dark brown with a distinct coppery or bronzy tinge, and in 

 having the head broadly depressed between the eyes and confluently 

 punctured, the elytra clothed with long, fine, erect, brownish hairs and 

 with the sides nearly parallel to behind the middle, the lobes on the 

 anterior margin of the prosternum vaguely indicated, and the sub- 

 apical carina on the last visible abdominal sternite irregular and very 

 short. The markings on the elytra are variable in shape. 



ACMAEODERA AENEICOLLIS, new species 



Broadly elongate, cuneiform, strongly flattened above, broadly 

 rounded in front, strongly narrowed posteriorly, strongly shining; 

 pronotum, head, and underside of body aeneous, the pronotum orna- 

 mented with a broad, yellow spot on each side along lateral margin, 

 extending from base to near apex; elytra black, with a distinct vio- 

 laceous or gi-eenish tinge, and each elytron ornamented with yellow 

 as follows : The yellow markings variable but usually with a broad 

 fascia, more or less interrupted, along lateral margin, and two broad 

 transverse fasciae behind the middle. 



Head flat in front, slightly depressed between eyes, transversely 

 flattened behind clypeus, with a short, longitudinal carina on occiput, 

 rather deeply, coarsely, confluently ocellate-punctate, sparsely clothed 

 with rather long, erect, yellowish-brown hairs; clypeus broadly, 

 rather deeply arcuately emarginate in front. Antenna extending
