bends forwards exteriorly and admits an ivory-white short streak ; 

 near the base are several small pale spots and streaks, and on the 

 membrane a iew whitish oblong spots, ends of the three veins 

 touching the claval margin broadly ivory-white. Abdomen black 

 or brown, with the edges of the segments, lateral margins, and 

 apical segments pale. Genital valve of male very short, bluntly 

 rounded at the corners, the following segments composing a ligulate 

 cover, rounded at the tip. 



Length to tip of wiug-covers 3-3| mm. ; width of pronotum 

 I mm. 



This is a variable species, in which all the specimens at hand 

 differ from each other in amount and pattern of marking ; the 

 paler specimens lack the brown ring on the vertex, and have that 

 colour broken up in various figures. 



Agallia nigkica]S"s, sp. nov. 



Bla(.-k, polished, the tip of head a little more triangular than 

 in the preceding species. Vertex with a large black spot each 

 side, a line on the middle, two smaller dots below the upper ones, 

 the inner border against the eyes, and a band on the forward 

 margin also black ; front suboval, black, marked with traces of 

 pale fulvous on the middle and sides, tip of clypeus also fulvous ; 

 cheeks moderately wide, bordered and striped with pale fulvous ; 

 rostrum piceous, paler at tip. Pronotum much longer than the 

 vertex, obsoletely and minutely scabrous, feebly impressed each 

 side, black, sometimes with two large fulvous spots at base, and 

 usually with two small diagonal ones on the middle. Scutellum 

 short, with a spot in each basal angle and the margin ivory-white. 

 Legs more or less black, the coxae, knees, base and apex of femora, 

 and underside of posterior tibiae pale fulvous. Wing-covers black, 

 or brownish with the veins darker, the costal vein pale yellow ; 

 veins of the clavus and base of corium a little interrupted with 

 fulvous, origin of the corium and a short stripe a little farther 

 beyond ivorj'-white, the two middle apical cells longer than wide, 

 subquadrangular. Abdomen mostly black, robust and not taper- 

 ing in the male. 



Length to tip of wing-covers 2i-2f mm. ; width of pronotum 

 I mm. 



Eight specimens of this dull-coloured species were collected on 

 the island. 



Agallia fascigeea, sp. nov. 



Pale yellow, robust, with a wide head and somewhat wedge- 

 shaped form. Vertex short, \nde and blunt, with a black dot each 

 side of the middle and sometimes a line in the centre ; the front 

 about one-half longer than its upper width, situated below the seat 

 of the antennae, scarcely separatJed from the vertex, pale soiled
