Agallia albidula, sp. nov. 



J?ale fulvous, robust, \^ath the head a Utile more convex than in 

 A. fascigera. Vertex of medium length, convex in front, either 

 pale fulvous, or yellow tinged with green, obsoletelj marked A\ith 

 testaceous spots, a brown dot on each side of the summit, on aline 

 with the paler brown ocelli ; surface sericeous, not punctate, obso- 

 letely incised on the middle ; front narrow and scarcely one-half 

 longer than width of base, the summit distinctly triangular, the 

 lateral basal angles triangularly produced, emarginated beneath 

 this, middle with a pale spot near the summit, and a long oval pale 

 spot iuferiorly ; superior cheeks dusky, spotted v(-ith yellow below 

 the eyes, inferior cheeks yellow ; tylus yellow, with abro\yn stripe 

 on the middle ; the rostrum long, slender, testaceous, piceous at 

 tip. Pronotum transverse, of medium length, moderately convex, 

 scarcely scabrous, faintly sericeous, pale testaceous, marked with 

 a triangular pale brown spot each side, two dots near the front 

 mart'in, a line on the middle, and sometimes two small spots near 

 the humeral angles ; the postero-lateral margins obliquely curved, 

 the anterior margin regularly curved, causing the outer angles to 

 be almost acute. Scufellum short, depressed and spoted on the 

 middle, testaceous, with the tip acuminate. Legs dull testaceous, 

 the apex of the tarsi, including the nails, piceous. Wing-covers 

 faintly dusky ; the veins, costal area, an angular mark on the tip of 

 the basal areole, and a large oblong spot extending to the middle 

 of the clavus yellowish white, the tip of this spot is bounded by a 

 curved brown mark, the apical portion of the clavus dusky hyaline ; 

 base of the corium, two faint spots beyond the basal areole, two 

 others on the middle, the apical margin, and the tip of the clavus

 valve of male triangular, the following pieces wide at base, tapering

Length to tip of wing-covers 3^-3f mm. ; width of pronotum 

 1 mm. 



More than a dozen specimens, including incomplete states of 

 coloration and texture of wing-covers, were taken at various 

 localities on the island. 



Besides the foregoing species, the collection from St. Vincent 

 includes several small Jassida;, related to TiipMoofhn, Chloi-ita, 

 Alehra, and Zi/<jina, which cannot be satisfactorily determined for 

 want of access to the types of the various authors who have de- 

 scribed these insects.
