138 THE CANADIAN ENTOMOLOGIST. 



of the scutellum and more obscurely on the sides of the pronotum and 

 tergum. Two spots on the base of the vertex, three longitudinal lines on 

 the pronotum, the lateral broader and abbreviated before, the basal mar- 

 gm of the clavus, and about eighteen spots on the elytra, white ; the latter 

 coalescing in places, and forming about four transverse bands ; the two 

 transverse veinlets bounding the postnodal areole brown ; nervures fulvous, 

 rather strong. Wings faintly enfumed, highly iridescent, nervures brown. 

 Anterior edge of the vertex with six black points, the. two median approxi- 

 mate ; base of the front with a black concentric line, crossing the temples 

 and interrupted at the middle and below each ocellus. Claws and antenna! 

 seta3 brown. Tibial spines deeper fulvous. Face with an obsolete pale 

 median line. 



The male is a little more deeply coloured than the female, and has the 

 two inner transverse nervures beyond the apex of the clavus brown, and 

 the wings are more deeply fuliginous. 



Described from one male and two female examples taken at Philadel- 

 phia, Pa., by Mr. C. W. Johnson. This is, perhaps, the most delicately 

 beautiful little Jassid as yet described from our fauna, and it affords me 

 pleasure to dedicate it to Mr. Johnson, who has brought to notice many 

 interesting forms of the Jassidce from Eastern Pennsylvania and New 

 Jersey. 



This is the smallest species of Eutettix yet described. It has nearly 

 the colour and markings of Paramesiis vittelliniis, and the size and form 

 of F. Twi?iingi, and might readily be mistaken for a member of that 

 genus, but the elytral neuration and most of its characters are those of 

 Eutettix. 

 3. Eutettix clarivida, n. sp. 



Form nearly of Eutettix seminuda. Pale greenish-yellow, anterior 

 edge of the vertex with a distant pair of large black spots and two brown 

 points at the apex. Length, 4^ to 5 mm. 



Vertex hardly ^ longer on the middle than next the eye, just ^ the 

 length of the pronotum ; marked with an impressed median line on the 

 base, either side of which is the usual impressed area near the outer angle 

 of the disc, and anteriorly is the transverse subapical depression common 

 to this species of this genus. Front ^ longer than wide, clypeus scarcely 

 expanded apically ; cheeks as in seminuda. Valve of the male broad- 

 triangular, about the length of the last ventral segment ; plates about 

 twice the length of the valve, their outer edges distinctly arquated near
