while sweeping in typical cane-brake near Tupelo, Miss., 

 July 1, 1921; one of these was taken on hackberry, Celtis 

 occidentalis, overhanging the brake. In Prof. Osborn's 

 collection there is a pair taken by C. J. Drake at Gainesville, 

 Fla., July 21, 1918, and a male from Lawrence, Kansas, 

 taken in June by E. S. Tucker. 



Oliarus difficilis VAN DUZEE 

 (1912 Bui. Buf. Soc. Nat. Sci., x, p. 494) 



Known only from Florida. 



The original description is quoted here. 



"Smaller than slossoni with the vertex broader, the 

 clypeus proportionately shorter, the mesonotum paler be- 

 tween the lateral carinae and the elytral nervures distinctly 

 punctate. Length 6 mm. 



Vertex much narrower than in slossoni but still at least one-half 

 times longer than broad. Front broad, but proportionately longer 

 with a narrower base than in either slossoni or aridus, the median 

 carina distinctly but narrowly forked at base while in both of the 

 allied species this fork is as broad as long and is obscure in aridus 

 and almost obsolete in slossoni. Clypeus scarcely longer than the 

 front, about twice as long in both the allied species; very minutely 

 transversely striate, and viewed from the side or below exhibiting 

 heavy oblique striae. Pronotum very short. Mesonotum tricarinate. 

 Elytra proportionately a little broader than in slossoni, the nervures 

 heavy, evidently but not strongly punctate, the anastomoses heavily 

 infuscated; stigma large as in aridus. 



Color piceous brown, almost black in places; carinae of the head 

 and pronotum, margins of the abdominal segments, tegulae and apex 

 of the mesonotum testaceous; disk of the mesonotum pale castaneous 

 between the lateral carinae; apex of the front with an indefinite paler 

 spot on either side of the base of the clypeus; clypeus almost fulvous 

 in one example. Mesosternum and pleura whitish as in the allied 

 species. Legs brown, becoming paler toward their apex, the inci- 

 sures pallid. Elytra obviously whitish-hyaline, nervures pale, fusco- 

 punctate, infuscated only on the forks, transverse veins and at apex; 

 commissural nervure twice alternated with white. Nervures of the 

 wings slender, fuscous. In one example the base of the elytra bears 

 a fuscous cloud as in slossoni and humeralis. 



Described from two females taken at Belleair, Fla., by 

 Mrs. Annie Trumbull Slosson."
