once evident from Sharp's description of the male protarsal claws 

 that he had something quite different in hand. The original of Sharp's 

 description is now before me and may be briefly characterized as 

 follows. 



Rather larger but precisely similar in horizontal outline to texanus Shp., but dis- 

 tinctly more strongly convex in profile : color shining black, with a sublateral 

 posterior yellow vitta of variable distinctness; hind margin of prothorax broadly 

 subangularly rounded at middle (broadly evenly arcuate in semi-vittatus} ; elytral 

 reticulation very fine, meshes very small and subequal throughout, the minute 

 punctulation evenly distributed and distinct under sufficient amplification : protarsi 

 of male rather feebly dilated but quite strongly compressed, the glandular pubes- 

 cence beginning at about the middle of the basal joint; claws rather short, the 

 anterior one with a strong angulate basal lobe, the posterior one broader but not 

 lobed at base. Length 8.5 to 9 mm. 



In semivittatus and stagninus the elytral reticulations are unequal 

 and quite irregular in form and much less minute, the fine punctules 

 excessively small and few in number. 



Described from four examples (30?, i?) from the British Museum, 

 two of which bear the label "St. John's Bluff, E. Florida." The 

 other two are probably from the same source though carrying no 

 locality label other than "Am. bor." 



Since writing the above I have received three examples (2c?'s i?) 

 from Mr. W. S. Blatchley, collected by him at Dunedin on the West 

 Florida Coast ("2-22-22"). The male tarsal characters are precisely 

 as in the East Florida type and there can be no doubt of their identity. 

 The Dunedin specimens differ however in having the meshes of the 

 elytra in the baso-sutural region distinctly unequal while in the 

 female this inequality extends throughout the surface, the reticulating 

 lines deeper and the surface less shining. 



The type of johannis is returned to the British Museum ; paratypes 

 in my own collection include one male ("Am. bor") from the Sharp 

 collection and the three Dunedin specimens mentioned.

Extremely similar in nearly every feature to semivittatus, but of somewhat 

 larger size, and distinguishable with certainty by the male tarsal characters. The 

 anterior tarsi of the male are here quite distinctly dilated, the glandular hairs 

 covering the apical half of the basal joint beneath as is usual. The front claw 

 of the protarsus is not toothed, but the strong rectangular basal angulation is 

 much more conspicuous than in semivittatus. As in the latter species, the ex- 

 tremely minute punctures occur on, and usually at the intersections of the reticu- 

 lating lines, and not within the areolae. Length 9.2 to 10 mm. 



This species is far moie restricted in range than semwittatus. It is 

 personally known to me only from Pennsylvania (Harrisburg), New 

 Jersey (Anglesea), and North Carolina. It is given in the South-
