698 REVISION OF THE GENUS PAROPSIS, 



entirely without doubt as to their sex. If it should prove that I 

 have not seen the male (and that the sexual characters in the 

 tarsi are not strongly different from those of P. Niohe) the male 

 of this species would no doubt be found to differ from that of I^iohe 

 by its wider form and shorter less infuscate antennae with apical 

 four joints more abruptly dilated as compared with the preceding, 

 joints. 



P. CHLOROTICA, OKv. (? vii'idiila, Chp.) 



There seems to be no particular reason for objecting to this 

 identification, although Olivier's description is insufficient to 

 warrant any great confidence in it, and it is quite possible that 

 (if the type can be examined) it may need correction. The insect 

 to which I attribute this name is a small species (long. 1^-lf lines} 

 notable among its immediate allies for its decidedly convex form, 

 looked at from the side, the upper outline of its elytra forms a 

 continuous well-marked curve (in 7-*. Niohe, nifjritula, Arc, that 

 outline is nearly straight for a considerable portion of its length). 

 It is also notable for its very wide flat head, the puncturation of 

 which is exceptionalh^ coarse, deep and sparse. Its shape is widely 

 oval (much as in P. nigritula, Clk.), but by no means circular. 

 There are few more variable Paropses in respect of colour 

 and markings (unless I am confusing several very closely allied 

 species). The specimens before me vary from entirely testaceous 

 or greenish, through forms in which the head, prothorax, elytra 

 and under sui'face are variously blotched with fuscous or black, 

 and others in which the whole elytra except the lateral margins 

 are black, to an extreme form in which the whole upper surface 

 except a narrow testaceous edging of the prothorax is black. 

 The localities of my specimens are in S. Australia, Victoria and 

 N.S. Wales. 



N.B. — Some varieties of this species are scarcely distinguishable 

 in respect of colouring from the typical form of P. nigritula, Clk., 

 but are easily separated from it by their much more convex shape 

 and the stronger and sparser puncturation of their head.
