is evidently (but not much) shorter than the prosternum. Com- 

 pared with N. viQ'idis, Blackb., (Trans. Roy. Soc. S.A., Vol. XI., 

 p. 177), this species is larger and more robust, with the elytra 

 much wider behind, and is coloured quite differently. The claws 

 (as in iV. viridis) have an obtuse rather large tooth at the base.

 Royal Society of S. Australia, an accomplished zoologist to whom 

 I dedicate this interesting little species. 



COCCINELLID.E. 



Chilocorus Baileyi, sp.nov. 



Hemisphsericus ; nitidus ; capite, antennis, palpis, corpore sub- 

 tus, et pedibus, testaceis ; prothorace nigro, lateribus late (et 

 margine antico anguste undulatim) rufis ; elytris totis nigris ; 

 capite prothoraceque leviter sat crebre, scutello elytrisque paullo 

 fortius minus crebre, punctulatis ; his ad humeros rotundatis, 

 haud productis. [Long. 2 J, lat. 2 lines. 



Regarded from the side the upper outline appears as a very 

 strong curve, its highest point being scarcely in front of the 

 middle; at that point the height {i.e., the distance through the 

 body to the surface of the sterna) is 5 of the length of the whole 

 "body. 



Compared with the European C. renipustidatus, Scriba, this 

 insect is more strongly convex, with the shoulders of the elytra 

 much less prominent and the puncturation of the same much 

 stronger. 



The only Australian species of Chilocorus previously described 

 are C. Australasice, Kerv., and rubidtcs, Hope. Unfortunately, 

 the description of the former (beyond the statement that it is 

 hemispheric and shining) gives no information whatever except 

 regarding the colour and markings ; though these are widely 

 different in the present species I should not venture to treat them
