Prothorax small, not longer than wide, black, sides usually yellow, elytra 

 not sinuate on the sides, about four times wider behind than at the base, 

 reticulations wider than long, irregularly divided in places ; fulvous, apical 

 one-third black ; frequently with a more or less perfect broad black band in 

 front of the middle ; % seventh ventral emarginate, eighth parallel, round- j 



ed at tip, side valves usually visible, rounded at tip. Length 11 — 16 mm. ^ /

a. — Transverse black band of elytra not extending to the sides. D. dorsalis

 p. — Transverse black band wanting, terminale Say. 

 4. — Prothorax wider than long, sides usually rarely entirely black fulvous, more 

 broadly reflexed ; elytra not sinuate on the sides, about three times wider 

 behind than at base, first and third eostse finer and less elevated than the 

 second and fourth, reticulations wider than long, irregularly divided in a 

 few places; fulvous, apical one-third black; also with a broad black band 

 in front of the middle extending along the suture to the base ; % seventh /V 

 ventral emarginate, eighth elongate, narrowed towards the tip. Length />/

a. — Band of elytra not extending along the suture, sometimes not attaining V 



the sides; q^we Lee. . i>' V

Prothorax smaller and more triangular, otherwise similar to typiciim, except 

 - that the first and third eostse of the elytra are very feeble, and the reticu- 

 lations are not transverse but mostly quadrate. Length 8.5 — 11 mm. Ariz., 



one 9; Mr. Bolter retiferiini n. sp. 



o. — Elytral band Very narrow, scarcely attaining the sides; Col., one %; 

 seventh ventral deeply emarginate, eighth elongate, narrowed to- 

 wards the tip. 

 5. — Narrower than the other species, proportioned like Celetes basalis, black, pro- 

 thorax and elytra fulvous ; the former a little wider than long, sides sinuate, 

 apex bisinuate and angulated at the middle, tip of the angle rounded ; front 

 angles prominent, rounded, hind angles acute, prolonged, carina of disc 

 strong, dusky; sides concave, margin reflexed; scutel fulvous, impressed, 

 nicked behind. Elytra gradually slightly wider, one-third wider behind 

 than. at base; suture, margin, and three discoidal eostse strongly elevated, 

 reticulation somewhat transverse; antennse strongly serrate, joints 3 — 10 

 nearly equal in length, broadly triangular, ariterior side curved, distal side 

 oblique, angle acute ; last joint of maxillary palpi longer than wide, parallel 

 on the sides, rounded at tip. Length 9 mm. Ariz., one 9; M''- Bolter. 



tricariiiatiiiii n. sp. 



This species by the form of the palpi, antennae, and number of elytral 



costae, seems to indicate a distinct genus, to which a name has probably 



been already attached, though I have failed to identify it in any of the 



works within my reach. 



Calopteroii retiieruni.— Black, beneatli mouth and joints of legs and 

 base of antennse tinged with testaceous. Antenna? two-thirds as long as the body, 

 very broadly compressed, second joint very short, inconspicuous, third not as long 

 as the fourth, outer ones gradually a little narrower. Palpi broadly dilated, last
