THE CANADIAN ENTOMOLOGIST. 291 



Callistochermes, gen. nov. 



Belongs to that section of Apkalarince, F. Low, which James 

 Edwards apparently includes in Chermin.'e ( = Psyllinse), characterized by 

 the frontal cones being well developed ; the cubital petiole is about as 

 long as the basal part of the subcostal nervure. The form of the 

 dorsulum and mesonotum recalls the Triozinse rather than either the 

 Cherminje or Aphalarinfe. ' 



Head strongly declivous ; dorsum strongly transversely impressed, 

 about three times as wide as long, lateral margins diverging slightly 

 anteriorly, posterior margin slightly angularly emarginate. The eyes are 

 attached to the side of the head, and appear suboblique, postero- 

 laterally they are on a level with the very short transverse, linear prono- 

 tum. Vertex and frons longitudinally sulculate very distinctly ; frons very 

 transverse, with an apical ocellus. Cones bullet-shaped, as seen anterior- 

 ly; from beneath they are seen to be narrow at their base and obliquely 

 elongate, contiguous apically. The other ocelli are on the posterior 

 margin of the vertex, subcontiguous to the eyes, which are prominent, 

 transverse, substylate, together almost as wide as the vertex. Head and 

 eyes much wider than thorax. Dorsulum* octohedral, somewhat convex 

 and declivous, much longer than the pronotum ; mesonotum convex, a 

 trifle longer than the dorsulum. Tegmina elongate, apically rounded, 

 costa arched. Basal part of subcosta curved, about equal in length to 

 petiole of cubitus, much longer than the part of the subcosta between 

 basal part and radial forking. Stigma short, subtriangular. All the 

 nervures more or less sinuate or curved. 



C. rtibrovariegata, sp. n. — -Anterior half of vertex crimson, freckled 

 with pale greenish and dark brown ; posterior half of vertex, the prono- 

 tum and dorsulum dark greenish-brown, freckled with crimson and 

 whitish. Frons pale greenish-white, cones obscure greenish. Eyes 

 grayish-green. Ocelli red. Antennae pale greenish-yellow, tip of each 

 segment blackish-brown. Mesonotum pale greenish-white, freckled with 

 black, with a linear median and broad lateral pale crimson bands 

 longitudinally. Scutellum pale greenish, with a medio-longitudinal stripe, 

 which at its middle has a very short line at right angles on each side. 

 Abdominal tergites dark greenish-brown, posterior margin narrowly 

 crimson. Tegmina subhyaline, colourless, freckled all over with blackish-
