EPILACHNA. 239 



E. olivacea, and differing from that species in colour. The upperside is pitchy, with 

 the head and thorax and the margins of the elytra pitchy-red ; the whole of the under- 

 side, with the legs, mouth, antennae, and epipleurse, is pitchy-red. The thorax has 

 often three obscure oblong pitchy spots, but often only the middle one is visible. The 

 punctuation is very fine, but just visible. The suture is paler, and the pubescence has a 

 plum-bloom appearance. Although allied to E. olivacea and E. tristis, I have little 

 doubt the five examples captured by Mr. Champion at Bugaba represent a very distinct 

 species. 



7. Epilachna tristis. 



Oblonga, subovata, nigra, confertissime minute punctata, pube brevissima cinerea vestita; elytris margine 

 ampliata, antice latissimis ; labro, geniculis tarsisque subtus flavescentibus. Long. 10 millim. 



Hab. Mexico, Chiapas (Salle). 



The labrum, base of the palpi, antennse (excepting the club), tips of the femora and 

 extreme bases of the tibiae, and the basal joint and soles of the tarsi in this insect are 

 rufous, all the other parts being black, with a faintly bluish tint. The most important 

 distinction between this and R olivacea, and that which leads me to give it specific 

 rank, is the widened epipleural margin at the base, the elytra there being twice as 

 wide as the thorax, thus bringing this species into Section A. It will be seen that in 

 K olivacea the thorax is not much narrower than the elytra at their base. And this is 

 a character on which Mr. Crotch attempted, and I think with some success, to divide 

 the perplexing forms of E. proteus into species. One example only of this insect has 

 been received ; it was labelled E. obscurella in the Salle collection, which species, 

 however, it only resembles in having the legs nearly black.
