170 CASEY 



gently, evenly convex, with sparse though distinct punctures, the fifth 

 ventral with the somewhat narrow tip very feebly sinuato-truncate. 

 Length 14. 5-18.0 mm.; width 5.6-6.9 mm. Kansas. [=Buprestis

5 — Form nearly similar to the preceding, the size very much smaller, cupreo- 

 seneous; prothorax subtransverse, narrowed from the base anteriorly, 

 the sides broadly rounded, the surface roughly punctate, the median 

 vitta rather wide, smooth, with another not very distinct at each side; 

 elytra striate, in general densely punctured, variegated with obscure 

 smooth spots, the apices truncate and slightly bidenticulate; abdomen 

 ( 9 ) with the fifth ventral entire and rounded at apex, the prosternum 

 subglabrous. Length 12.0 mm. Maryland (Baltimore) .. debilis Lee. 



There has been a tendency among various recent authors to sup>- 

 press both erecta and debilis, but I do not hold this to be justifiable; 

 the former is the widely dififused eastern form, with brilliantly cup- 

 reous apex of the elytra and blue tarsi, usually identified in cabinets as 

 cyanipes, which however is a very different and far western species, 

 probably rather rare in collections. 



Anataxis n. gen. 



Although the prosternum in this genus is almost exactly as mPoecilo- 

 nota, — broadly convex between the narrow lateral sulci, — both the meta- 

 sternum and first ventral are broadly and evenly convex, and, that we 

 have here a remarkably isolated type, not at all closely related to any- 

 thing that precedes, is amply shown in addition by the transversely 

 parallel hind coxae, parallel inner margins of the eyes and by the 

 antennal structure. The body is cuneiform, convex and not unlike 

 AcmcBodera in general outline, the evenly convex front feebly impressed 

 medially, the epistoma depressed and sinuato-truncate, the labrum 

 short, sinuate and closely, stiffly pubescent, the mentum transverse, 

 corneous, metallic and medially produced in a narrowly rounded 

 prominence at apex and the maxillary palpi slender and moderate 

 in length. The antennae are short, compact, somewhat as in Dicerca 

 but with the third joint longer than the second or fourth, the outer 

 joints transversely and obtusely serriform, their outer sides smooth 

 but having each a very large oval sensory intero-apical fossa, and 

 another, smaller and transversely oval, near the base of the joint, with 

 a number of coarse sensitive punctures between; they are inserted in 

 small and widely separated foveas, which have their upper margins 

 slightly j)romincnt. The prothorax is evenly convex, excepting a feeble
