13. — Hind angles of prothorax distinct; upper surface shining, elytra with two 

 or three outer strise distinct 14. 



Hind angles of prothorax rounded, upper surface usually opake very 



strongly punctured, elytral interspaces convex 15. 



14. — Black, above mottled with yellow, prothorax with narrow lateral and 

 apical margin, short anterior line and two small basal Sf)ots yellow; 

 elytra with two convex interspaces near the sides; basal margin, apex 

 and a few irregular small spots yellow ; head and legs varied with yellow 



spots; 3.5 — 4.5 mm.; Cala 20. Itistrans n. sp. 



a. — Black, head slightly spotted. 



Beneath black, legs and upper surface yellow, mottled with brown, punc- 

 tures of elytra somewhat less confused, outer interspaces not elevated; 

 tarsi blackish; 4.8 mm.; Veta Pass, Col. ; one 9 •••21. renilleiis n. sp. 



Beneath black, legs ferruginous, tibipe and tarsi dusky, upper surface dirty 

 yellow, mottled with brown; prothorax with three brown stripes, the 

 middle one divided in front, the side ones shorter; elytra with the strije 

 not much confused except near the scutel, interspaces not very convex, 

 with three subniarginal spots and a dislocated interrn])tGd dorsal vitta 



brown; 3.5 mm.; Texas.* 22. StibvittatuiS n. sp. 



15. — Yellow and brown, elytral strise sinuous not approximate, intersjiaces 

 rather wide, with a few confused punctures only near the base; beneath 

 brown, legs and upper surface yellow mottled with brown; prothorax 

 rather densely but irregularly punctured, sides oblique in front, rounded 

 behind, basal angles almost rounded, elytra irregularly fasciate with 

 brown; 3.5— 5 mm.; Tex 23. turbidus n. sp. 



Black, opake in great part, mottled with small white dots on upper sur- 

 face ; prothorax densely punctured with a faint remnant of a smooth 

 dorsal line, sides oblique in front, rounded behind, basal angles almost 

 rounded; elytra confusedly coarsely punctured over the greater part of 

 the surface, strise visible at the sides and behind, approximate, inter- 

 spaces narrow; cescuii Me\s., mcerens St3i\.; 3.2— 4 mm.; Pa.; Ga. ; Tex. 



24. luridu!^ Fabr. 

 a. — Prothorax red at the sides, femora with a yellow spot. 

 fi. — Prothorax entirely red, femora spotted; Texas. 



Smaller than luridus, opake black; elytra with fewer confused punctures, 

 and more white spots; legs in great part testaceous; pygidium spotted 

 with testaceous; 2.6 mm.; Ga. ; one specimen. (Perhaps not different 

 from luridus) 25. femoratus Oliv. 



Black, legs testaceous, thighs with a dusky spot; above mottled with 

 small white spots; prothorax nearly three times as wide as long, rounded 

 on the sides, basal angles rounded, surface densely punctured, with 

 irregular small smooth pale spaces, and anterior dorsal line; elytra with 

 irregular deep strise at sides and behind, base and along the suture con 

 fusedly punctured; pygidium spotted with testaceous; 3 mm.; Texas, 

 Belfrage, one specimen. | 26. brevicollis n. sp. 



® If the markings were more regular, and the punctures near the scutelluin 

 less confused this species might be placed near litigiosus. 



I Easily known by the very transverse prothorax; it greatly resembles some 

 of the forms in category 17, but the presternum is deeply and broadly chan- 

 neled and is narrower behind, as in nearly all the preceding species.
