NEW COLEOPTERA PROM THR LOO-CHOO ISLANDS. O 



a fluid which will despatch them with rapidity, it seems to me 

 that it ought to kill anything — in the insect way. 



There are other points, in the paper referred to, which I should 

 like to have touched upon, but I have already taken up too much 

 of your space.

DESCEIPTIONS OF SOME NEW SPECIES OF PHYTO- 

 PHAGOUS COLEOPTERA FROM THE LOO-CHOO 

 ISLANDS. 



By Martin Jacoby, F.E.S. 



Amongst a small number of Phytophaga kindly sent to me by 

 Mons. R. Oberthur, which he received from the island of Oshima, 

 there are several species which seem to be new to science. The 

 fauna of these islands is, of course, closely allied to that of Japan, 

 with which it seems to have many species in common. I recog- 

 nised Crioceris subpolitaj Motsch., Chrysomelaaurichalcea,M.otsch.y 

 and Cryptocephalus perelegans, Baly. The following species 

 appear to be undescribed : — 



Gynandrophthalma quadratomaculata, n. sp. 



Black below, as well as the head ; thorax and legs fulvous, the former 

 irnpuDctate ; scutellum black ; elytra testaceous, with four small black 

 spots near the suture ( ^ ), or three additional spots at the sides. Length, 

 2 lines. 



(^. Head broad, black, finely rugose between the eyes and strigose in 

 front of the latter; anterior margin of the epistorae narrowly fulvous, 

 triangularly emarginate; antennae fulvous, the five apical joints fuscous, 

 thickened, third and fourth small, equal ; thorax strongly transverse, of 

 equal width, the anterior margin straight, the posterior one slightly pro- 

 duced into a lobe at the middle, the sides much rounded at the base, the 

 surface with a transverse depression near the anterior margin and some 

 other indistinct ones near the posterior angles, impunctate, with the excep- 

 tion of a few punctures near the base; scutellum black, its apex distinctly 

 raised; elytra parallel, pale flavous or testaceous, finely punctured, the 

 punctures here and there placed in irregular rows, with four small black 

 spots placed quadrately near the suture, before and at the middle; the 

 under side (that of the thorax excepted) black; legs fulvous, the first joint 

 of all the tarsi elongate. 



In the female, the head is, as usual, smaller, and the thorax is less 

 transverse, the spots on the elytra are larger, especially those of the second 

 row which form the square, and, in addition, three others are placed at the 

 sides, one on the shoulder, a very small one immediately below, and the 

 third in a line with the last subsutural spot. 



This species differs in the pattern of the elytra from any of its 

 allies with which I am acquainted.
