68 PEOF. p. K. UHLEE — EyUMEEATIOX OF THE [Jan. 15, 



Veins of the wings mostly brown. Borders o£ segments of the 

 abdomen slenderly white, both above and below, exterior edge of 

 the connexivum also whitish. Tip of the venter densely loaded 

 \^T[th white flocculent matter. 



Length to end of abdomen 5 mm. ; expanse of wing-covers 

 12^ mm. 



Only a single specimen of this neat-looking species was secured 

 on this occasion. 



This genus resembles Mnemosyne^ Stll, in the shape of the vertex, 

 but differs in the type of pronotum as well as in the venation of 

 the wing-covers, 



Cheiloceps, gen. nov. 



General form of Issus, \\\t]x the wing-covers longer than wide, a 

 little tapering towards the tip, and the tip obliquely truncated. 

 Head narrower than the pronotiun, the vertex subquadrangular, a 

 little longer than wide, scooped out, the prominent keeled margins 

 projecting a little beyond and above the eyes, the middle line with 

 a slight keel ; the base of head triangularly emarginated. Eyes 

 very large, longer than wide. Front of medium width, growing 

 wider next the dypeus, with each side raised into a ligiiliform 

 relief which ends below in a button, middle of the front depressed, 

 oval, carinate on the middle line ; clypeus placed diagonally, 

 convex on the middle, carinated, with the lateral margins curved 

 near the base, acutely tapering towards the tip ; the base prominent, 

 and a little excavated on the margin. Pronotum a little shorter 

 than the head, but wider than the diameter across the eyes, trian- 

 gular, let into the base of the head, slender behind the eyes, but 

 expanding beneath them. Mesonotal shield ob triangular, wider 

 than long, with a transverse carina at base, from which a short 

 carina runs back on either side ; the scutellum small, acute. Wing- 

 covers moderately narrow, the costal membrane at base wide but 

 not abniptly expanded, longitudinal veins canied through to the 

 tip and curving forward there ; transverse veins few, mostly placed 

 on the apical third, the radial vein forked and curved at tip ; the 

 costal areola crossed by numerous veins beyond the middle. 

 Wings long and wide, cleft, with few and mostly large areoles, 

 the accessory membrane a little longer than the abdomen without 

 the genitalia. Posterior tibiae armed with two spines. Abdomen 

 broad, a little depressed, interruptedly carinate on the middle of 

 tergum. 



Cheiloceps mcsca, sp. nov. 



Fulvous, paler on the wing-covers. Middle of the vertex and 

 ground-coloui' of the front and clypeus pale smoke-brown ; lateral 

 margins of the vertex tinged with rufous, the other margins and 

 carina pale testaceous ; the raised sides of the front yellowish 

 irregularly spotted with dark brown, and the underside of the 

 buttons especially brown ; a whitish band crosses the upper portion
