AMERICAN COLEOPTERA. 203 



16 -Brown, antenniB and legs ferruginous, elytra pale yellow, with three in- 

 terrupted brown vitt» forming spots occupying the alternate intervals; 

 medial spots usually confluent into a large common transverse brown 

 blotch ; striffi composed of rather distant punctures, the two next to the 

 outer one irregularly connected, and with a short intermediate series; 

 prothorax ferruginous, with or without basal spots, sides yellow; pro- 

 sternum not lobed in front, emarginate and acutely toothed behind; 

 t, p: dispcrsusll&ld.; 4-7 mm.; Pa.; 111.; Ga.; Ks. ; Tex. 

 ° * 33. mutsabilis Mels. 



Varies with spots more or less confluent. 



Varies also with the prothorax smooth or distinctly punctured. 

 a -Prothorax smooth, with the bead of the margin, a very broad dorsal 

 stripe, and a spot each side black; spots of elytra and under surface 

 black; antennffi and legs ferruginous; ?; Arkansas, (Bolter). 

 Ferruginous or brownish yellow; prothorax smooth or nearly so, and very 

 shining; elytra yellow, with three transverse undulating brown fasciae 

 formed by confluent spots; stri» impressed, punctured, the two next to 

 the outer one interrupted, and connected transversely; prosternum not 

 lobed in front, feebly emarginate behind; % $; 3.8-5 mm.; Texas. 



34. f ulgurattis n. sp. 

 Less robust, brown: prothorax shining, sparsely punctulate, apical and 

 lateral margins and hind angles sometimes yellow; elytra with impressed 

 strongly punctured brown strise, the two next the outer one (sixth and 

 ei<Thth to wit, the seventh being represented by only a few punctures), 

 interrupted and connected transversely ; ground color brown, with yellow 

 marks as follows; a basal band composed of confluent spots extend- 

 ing to the sixth stria, a marginal transverse spot just before the middle 

 extending inwards to the fifth stria; an interrupted transverse band 

 behind the middle, and an apical spot; prosternum not lobed in front, 

 deeply emarginate and acutely lobed behind; % ?; 3-4.2 mm.; Pa.; 



Ky.; Fla» 25. badius Suff-r. 



a.— Interval between the third and fourth stria with a small yellow spot 

 before the middle. 

 17 -Cylindrical testaceous, tinged with brown; prothorax densely aciculate; 

 elytra with ten regular deep punctured strise; % ?; rvgicollis \\ Hald.; 



3-4 mm.; Mass.; Ga 36. Schreibersii Suffr. 



More robust, testaceous tinged with rufous ; prothorax densely and coarsely 

 punctured; elvtra with ten coarsely punctured strise, seventh and eighth 

 confused; usually obsoletely trifasciate; % 9; 3-4.5 mm.; Mass.; Fla. ; 



jll J Tgx 37. tiiictiis n. sp. 



Of the same form and color as the preceding, prothorax densely and 

 coarsely punctured; strise of elytra irregular, the outer ones confused, 

 and therefore seemingly more numerous; elytra indistinctly fasciate 

 with rufous; prosternum deeply emarginate, excavated, and acutely 

 bilobed behind; ^ ; ? /a6Ctafas Say ; 3.5 mm.; Ga...38. lateritilisXewm. 



«The elytral pattern of this species has the same type as the two preceding, 

 and diff-ers only by the greater extension of the brown color; the three are 

 however readily distinguished by the prosternal characters, and the differences 

 in the elytral strire, as above described. They form however, a little group 

 suflicicntly from any of the preceding ones.
