﻿116 THE ENTOMOLOGIST. 



piceous above ; thorax about one half broader than long, the sides rounded and 

 widened, very obsoletely angulate below the middle, the anterior angles slightly 

 pointed, the surface very strongly and rather closely punctured, a narrow 

 longitudinal central space as well as the extreme anterior margin, smooth ; 

 elytra convex, strongly rounded towards the middle and pointed at the apex, 

 the punctures rather finely impressed but distinct to the apex, the base with 

 a shallow transverse depression, only visible in certain lights, the interstices 

 above this depression subtuberculate (male), or subcostate (female), the sides 

 in the female also furnished with a short costa below the shoulder and a 

 longer one further inwards ; the four posterior femora minutely toothed. 



This species, which has all the characters peculiar to the 

 genus, is much distinguished by its shape and the sculpture of 

 the elytra ; the thorax also is longer than is usually the case, and 

 its sides are scarcely angulate. 



A few examples. 



ClEORINA LEFEVREI, n. Sp. 



Metallic dark blue or violaceous ; antennae black, the basal two or three 

 joints fulvous ; finely and moderately closely punctured ; elytra with a 

 transverse depression below the base, finely punctate-striate. Length, 

 U— If line. 



Of broadly ovate shape, the head rather closely and distinctly punctured, 

 the epistome not separated from the face, the anterior edge of the clypeus 

 deeply concave-emarginate ; antennae less than half the length of the body, 

 black, the third and fourth joints of equal length, the lower three fulvous, 

 the basal joint stained with metallic-blue above ; thorax transverse, twice as 

 broad as long, the sides nearly straight, the surface punctured like the head, 

 the punctures subremotely placed; scutellum impunctate, broad, its apex 

 acute ; elytra with a deep transverse depression below the base, the 

 shoulders prominent, the punctured striae fine (except within the depression), 

 nearly indistinct at the apex. 



Closely allied to C. janthina, Lefev., but quite distinct. 

 Numerous specimens were obtained. 



Chrysomela seriepunctata, ? Weise. 

 The description of this Chrysomela from Siberia, by the 

 author in Wiegmann's ' Archiv,' 1887, agrees so closely with the 

 specimens from Chang Yang, that I must refer them to that 

 species, the more so as the very numerous and variable species 

 already described, from the East, are for the greater part very 

 difficult to separate. The present insect is entirely metallic dark 

 blue, the thorax is very finely and rather closely punctured on 

 the disc (Weise says not closely), and the sides have a deep row 

 of coarse punctures (deepest near the base), which limit the 

 nearly smooth lateral and slightly raised marginal space; the 

 elytra have numerous rows of strong punctures, which only at 

 the sides can be distinguished as being arranged in pairs, the 

 interstices are nearly as strongly, sometimes more finely, punc- 

 tured. All this agrees with the author's description. 



Chrysomela sibirica, Weise. 

 Numerous specimens, agreeing entirely with the author's 

 description, were obtained by Mr. Pratt ; the upper surface of the
