THE CANADIAN ENTOMOLOGIST. , 159 



Last ventral segment of female twice the length of the preceding, 

 shallowly trisinuate, the median sinus acute. 



Described from two specimens from the Cornell University collec- 

 tion, kmdly sent me by Mr. A. D. Macgillivray, collected at Ithaca, N. Y., 

 the female on Aug. 3rd, 1S89. This insect might readily be mistaken for 

 a PhleJ)sius. 



Dorydiella, n. gen. — Head broader than prothorax and somewhat 

 longer, more than twice as broad as long, anteriorly foliaceous, angulate, 

 and inclined upward. Face normal. Ocelli on the edge between vertex 

 and face, adjoining the eyes. Elytra long and narrow, with a narrow 

 appendix, somewhat exceeding abdomen, toward the apex narrowed to an 

 acute point. Apical cells four, anteapical two, basal cross vein entering 

 radial cell. Clavus with two longitudinal veins. Wings with three apical 

 cells exclusive of the closed costal. 



This genus is much like Dorydium in everything except the head, 

 which is far shorter. Type : — 



Dorydiella florida^ia.. n. sp. — $ . Length, 8 mm. Pale sordid 

 whitish. Face variously marked with fine light brown dots, leaving 

 portions below, and several indistinct transverse bands above, light. 

 Vertex and pronotum with a number of very pale brownish indistinct 

 longitudinal stripes. Anterior edge of vertex with five dark dots. Elytra 

 with very sparse brownish ramose lines, densest about and extending 

 back from the second apical cell. A dark spot at apex of clavus. . 



Genae feebly emarginate below the eyes, then broadly rounded, 

 slightly exceeding clypeus. Lorje large, semilunar. Clypeus somewhat 

 narrower towards base, sides sinuate, apex truncate. Front with sides 

 nearly straight, rapidly broadened above where it is bent somewhat back. 

 Length of vertex three-fourths of width between eyes, somewhat longer 

 than pronotum. Pronotal width nearly two and a third times the length ; 

 anteriorly the pronotum is broadly rounded, the surface very sparsely 

 punctate and posteriorly finely creased, the hind margin gently concave. 

 Last ventral segment but little longer than preceding, hind margin with a 

 broad, blunt, median projection having a small notch at its extremity and 

 a black dot on either side. 



Described from a single specimen in the National Museum collection, 

 labelled " Fla." It is to be hoped that collectors doing miscellaneous 

 sweeping in Florida will look particularly for further specimens of this 

 rare and interesting insect.
