﻿NEW SPECIES OF LEPIDOPTERA FROM CHINA. 109 



17 (18). Punctures of the inner strise not, or scarcely 



finer than those of the outer. Dorsal 

 aspect of median lobe of cedeagus elon- 

 gate-triangular, apex acute ... ... 9. marinus, Gyll. 



18 (17). Punctures of the inner striae distinctly 



finer than those of the outer. Dorsal 

 aspect of median lobe of cedeagus elon- 

 gate-triangular, suddenly narrowed about 

 half-way from the base, and thence 

 parallel-sided to its subtruncate apex ... 10. opacus, Sahl. 



For the examination of the sculpture of the interstices in these 

 insects an amplification of about 40 diameters is very convenient. 



Both G. elongatus and G. bicolo7' are subject to considerable 

 variation in shape, some specimens being very narrow and convex. 

 In the English descriptions of the latter insect too great a point 

 is made of its more elongate and parallel form, as a means of 

 distinguishing the species from elongatus, — probably because 

 most, if not all, of the authentic British specimens pertain to 

 the var. angustatus ; but Dr. Sharp has kindly given me some 

 Swedish examples of veritable bicolor, not one of which actually 

 belongs to that variety, and which, so far as size and form are 

 concerned, I can exactly match with a few abnormally large 

 females out of an extensive gathering of elongatus. Here, how- 

 ever, the form of the elytral apices, and the colour of the meso- 

 sternum and apex of the abdomen, serve to separate the two 

 species. I mention this to show that a Gyrinus may be the true 

 bicolor without being exceptionally elongate, parallel-sided, and 

 convex. 



Several of our species have a dull form, resembling in that 

 respect the normal form of minutus ; I have it, in both sexes, in 

 svffriani, natator, marinus (in which species it is very frequent), 

 and opacus.

NEW SPECIES OF LEPIDOPTERA FROM CHINA. 



By J. II. Leech, B.A., F.Z.S., &c. 



(Concluded from p. 83.) 



Campylotes pratti, sp. n. 

 Agrees in design with Campylotes (Epyrgis) desgodinsi, Oberthiir (Etud. 

 d'Ent. 9, pi. xi. fig. 10), but differs therefrom in its larger size and in having 

 a black transverse basal band on primaries ; the inner portion of the basal 

 half of all the wings is decidedly yellow instead of salmon-pink, as in 

 desgodinsi. Further, the pectinations of the antennae are much longer. 

 Expanse, $ 70 mm., ? 82 mm. 



I received a number of specimens from Chang Yang. From 

 their fine condition these appeared to have been bred.
