small, head between eyes coarsely vermiculate, medio-basa! 

 portion polished and almost impunctate. Abdomen polished, 

 first segment (along middle) as long as hind femora, the three 

 following slightly shorter, fifth slightly longer. Length, bo 

 apex of elytra, 22-34 mm. ; of abdomen, 33-64 mm.

 Brown), Mullewa (Miss J. F. May). Type, I. 5769. 



The elytra are without distinct costae, but to the naked 

 eye appear to have two feeble longitudinal elevatiotis on each : 

 the apical half is thinner than the basal half, and on several 

 specimens appears to be almost membranous, an appearance 

 heightened by irregular shrinkage. The male differs from the 

 female in having the abdomen somewhat shorter and thinner 

 and antennae and legs somewhat longer. On some specimens 

 there is a small polished space on each side at the base of the 

 prothorax. 



CHRYSOMELIDAE. 



Eucolaspinus, new name. 

 Eu col as pis, Lea, n. pr. 



The name Eucolaspis was used by Dr. Sharp in 1886' 

 (Tr. Dubl. Soc), so that the above substitute is proposed for 

 the name Eucolaspis, recentlv used in the Eumolpides (ante,. 

 1915, p. 318). 



Subfamily CHRYSOMELIDES. 



The Australian genera of this subfamily niay, for the 

 present purpose, be regarded as belonging to two divisions — 

 1. Paropsis, and the genera or subgenera proposed (usually 

 on trivial grounds) at its expense. 2. All other genera. 

 Whilst the species of Paropsis may usually be readily identi- 

 fied as such, there are members of other genera that super- 

 ficially might easily be mistaken for same, jbut these may 

 usually be distinguished by the claws, palpi, antennae, and 

 elytral epipleurae. Whilst hoping later on to deal with 

 Paropsis, for the present my task has been confined to the 

 second division. Some of the genera of this division are 

 very distinct and may be easily recognized, but the claws 

 and palpi are so important that considerable manipulation 

 of specimens is cften necessary before they can be critically 

 examined. In a previous paper (2S) I did not attach sufficient 

 importance to these, with the result that several species of 

 Chrysomela were referred to Calomel a, (29! Some of the 



(28) Australasian Association for the Advancement of Science, 

 1902. 



(29) Some species of Chrysomela so strongly resemble some of 

 Calomela that even as species they are hard to distinguish from 

 same.
