AULACOPHORA ROSEA. 39 



I ara however inclined to believe that the larger of the 

 two forms is that described by Fabricius , as the colour of 

 the antennae which are flavous, with the exception of the 

 first joint , which is rufous , agrees well with the author's 

 description. In this form the black colour of the ely- 

 tra is divided obliquely at its posterior margin from 

 the red. 



In the smaller species the same colour is separated by 

 an almost straight line (as given by Guerin) but there are 

 specimens which vary in this respect. 



Aulacophora Batesi, n. sp. 



Oblong, widened behind. Underside and the 4 posterior 

 legs black. Head , thorax , anterior legs and antennae 

 fulvous. Elytra finely punctured, longitudinally costate(9?) 

 or simple, fulvous, posterior half black. — Length 4^/2 — ^^'^ 

 lines. 



This large sized species , which I also possess from Java, 

 has quite the colour and general appearance of Haplosonyx 

 semijiava Wiedem. from which the structural characters, 

 peculiar to Aulacophora at once distinguish it. I cannot 

 separate those specimens with costate interspaces of the 

 elytra , from those with simple ones , this character being 

 the only difference. In both, the first two joints of the 

 antennae are shining, the rest pubescent and more opaque. 

 The third and following joints are nearly equal, more than 

 twice as long as the second. The scutellum is either black 

 or fulvous and the latter colour of the elytra predominates 

 to a greater or smaller degree. The latter in the costate 

 specimens are opaque, in the other form more shining. 

 The last may possibly represent another species. 



The specimens before me are from Loeboe Gedang and 

 Soerian (Sumatra-Expedition) and from Soekadana (I. C. 

 van Hasselt).
