COPTOCYCLA THAIS. 



Coptocyda thais, Bohem. Cass. Suppl. iv. p. 463 ; Balv, 1. c. 

 p. 214; Kraatz. I. c. p. 2/1. 



Hab. Northern China ; Japan, many localities. 



Readily known by the pale rugse on the summit of the elytra 

 forming an x. Kraatz speaks of it as "very like C. biramosa"; — 

 I only see that it is like it in wanting a humeral dark ramus, it is 

 much smaller, and all the dark markings are more nearly black. 

 In one specimen the posterior ramus, which is usually so distinct on 

 the margin of the elytra, is quite wanting. Mr. Lewis found this 

 species commonly. 



CoPTOCYCLA SPARSA. 



C. thaidi affinis, sed minor, magis oblonga, sordide testacea, 

 prothorace vitta mediana antice abbreviata, elytrorumque disco 

 irrorato, fuscis, hoc ramulum postice emittentcparum nitidulis ; 

 ccrpore cum coxis nigra ; capite, antennis pedibusque Jlavis, 

 abdominis apice ntrinque pallido. 



Long. 5-5i millim. 



Japan, Nikko and Sannohe on main island, and at Sapporo in 

 Yezo (G. Lewis). 



Head yellow, sometimes obscurely so, antennae clear yellow ; 

 their apex faintly clouded ; termical joint not more infuscate than 

 those preceding it. Thorax bone-yellow, rather transparent, hence 

 the head shows through, causing the appearance of a vitta, which 

 does not attain the front margin ; hind angles round, base straighter 

 than in C. thais ; disk thickly punctured and but little shining. 

 Elytra longer than, and not nearly so convex as, in C. thais, punctured 

 in striae, but with rugoe here and there uniting two or more interstices, 

 but the pale rugae forming so conspicuous an X in C. thais are 

 here wanting, and the whole insect is duller. The posterior ramus, 

 though reaching the margin, is not very distinct from above, because 

 the margin is little expanded, and the dark markings of the disk 

 here widen outwards, as also they do in front, though there is no 

 front ramus ; underneath this posterior spot is quite clear black and 

 the apex of the suture has a black spot. This species is, with the 

 exception of C. spilota, the smallest yet detected in Japan. It is 

 about the size of C. hebraica. C. crucifera appears to be of the 

 same size, but the description does not accord with that of this 

 species, and it appears to be a much more glabrous and smooth 

 species. In C. sparsa the expanded margin of the elytra is covered 

 with deep punctures, which are confluent and interspersed with 

 rugae, especially near the edge of their raised disk. 



A series of about a dozen were secured by Mr. Lewis. 



CoPTOCYCLA SIGILLATA. 



Eotundata, breviter ovata, nitidissima, corpora sublus nigro-piiceo, 

 capite, antennis, pedibus, abdominis apice, maculisque nonnuUis 

 lateralibus testaceis ; prothorace diaphano, disco convexo, glabro.
