184 THE CANADIAN ENTOMOLOGIST 



Euscelis ozarcensis n. sp. Resembles arctostaphyli Ball Inil 

 can be distinguished by greater length of last abdominal segment 

 of female, the lateral angles of which are more produced, also by 

 having a much more simple colour pattern on vertex. 



Vertex obtusely angulate, apex produced, length two-thirds 

 that of width and about two-thirds length of pronotum. Front 

 broad and only slightly convex. Clypeus parallel-margined, 

 hardly twice as long as broad. Elytra short and broad, apical 

 cells small, central anteapical cell only slightly constricted on inner 

 side. Length 3 mm. 



Colour, decided brown, with anterior margin of vertex and 

 costal margin of elytra bright yellow. A transverse dark brown 

 or black band between anterior portion of eyes. Posterior margin 

 of vertex bordered with cream. Pronotum and elytra of same 

 intensity of colour. Scutellum light brown. Elytra nervures 

 prominent, very light brown to cream. Face marked with dark 

 cross-bars. Cheeks irregularly marked. Below dark; tibia pale, 

 pygofers blotched. 



Genitalia, last ventral segment of female twice longer than 

 penultimate, lateral angles produced; two slight notches, one on 

 either side of ovipositor. Male plates triangular and twice the 

 length of valve. 



Described from two females and two males collected by the 

 author in the Ozark Mts. near Branson, Mo., August 21, 1916, 

 and now deposited in the collection of the U. S. National Museum. 



Typhlocyba modesta, n. sp. Near rosce Linn., but differing in 

 female posterior segment being distinctly notched, and in larger 

 size. Face considerably longer than broad, clypeus less than one- 

 fourth the entire length of face, superior angle of face obtuse. 

 Length of pronotum hardly twice that of vertex. Scutellum large. 

 Last ventral segment of female produced and rather deeply notched. 



Colour, light yellow to cream, vertex slightly tinged with deeper 

 yellow. Thorax, scutellum and abdomen concolorous. Elytra 

 hyaline with apex tinged with yellow. Eyes brown; tip of ovi- 

 positor and tarsal claws dark brown 'to black. Length 3^ mm. 



Described from two females and one male collected by the 

 author at Charleston, Mo., during May and June, 1916, and which 

 are now deposited in the collection of the U. S. National Museum.
