NEW BUPRESTID BEETLES — FISHER 337 



Abdomen beneath rather sparsely, uniformly, finely, shallowly 

 punctate, rather sparsely clothed with moderately long, rather broad, 

 semierect, white haii^ ; intervals finely granulose ; last visible sternite 

 broadly rounded at apex, without a subapical carina. Prosternum 

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

 sparsely clothed with short, rather broad, semierect, white hairs; 

 anterior margin truncate. 



Length 5.5 mm., width 1.5 mm. 



Type locality. — Mexico, no locality given. 



ri/;?e.— U.S.N.M. No. 58789. 



Described from a single specimen collected at Brownsville, Tex., 

 December 21, 1937, in mesquite {Prosopis sp.) from Mexico. 



This species belongs to Horn's Truncatae group. It is very closely 

 allied to Acmaeodera neglecta Fall, but it differs from that species in 

 being more cylindrical, more strongly acuminate posteriorly, and 

 more strongly shining, and in having the strial punctures on the elytra 

 finer and more elongate, and the interstrial spaces two to three times 

 as wide as the strial punctures. 



ACMAEODERA KNABI, new species 



Narrowly elongate, subcylindrical, strongly convex above, broadly 

 rounded in front, strongly narrowed posteriorly, rather strongly 

 shining; head, pronotum, and underside of body coppery brown, the 

 latter with a distinct aeneous tinge ; elytra bluish black, with a dis- 

 tinct violaceous tinge, and each elytron ornamented with six small 

 yellow spots arranged longitudinally, three along lateral margin and 

 three on disk. 



Head flat in front, slightly depressed between eyes, transversely 

 flattened behind clypeus, with a narrow, longitudinal carina on vertex 

 and occiput, coarsely, shallowly, confluently alveolate-punctate, 

 sparsely clothed with long, erect, white hairs; clypeus broadly, deeply, 

 arcuately emarginate in front. Antenna extending to base of prono- 

 tiun ; segment 1 elongate, as long as following three segments united ; 

 segment 2 globose ; segments 3 and 4 narrower, twice as long as wide ; 

 segments 5-10 not compact, triangular, about as wide as long ; segment 

 11 oval. 



Pronotum one and three-fourths times as wide as long, narrower 

 at apex than at base, widest at middle; sides broadly rounded, with 

 the margins narrow, but not visible from above ; disk strongly convex, 

 narrowly, transversely flattened along anterior margin, feebly, longi- 

 tudinally grooved at middle, with three small f oveae along base, one 

 median and one on each side near posterior angle; surface densely, 

 coarsely, deeply, uniformly punctate, the punctures confluent toward 

 sides, and rather densely clothed with short, erect, inconspicuous 

 hairs.
