168 Mr. A. Murray on Coleoptera from Old Calabar. 



Prometopia, Er. 



The species belonging to this and some of the following genera 

 are of special interest from their geographical distribution, se- 

 veral of them being closely allied to forms characteristic of the 

 opposite part of the continent of America, and others showing 

 an affinity with the Indo-Malayan region. 



There are only two species of Prometopia as yet described, 

 viz. sewmaculata and confluentay Er., — the former from North 

 America, the latter from Columbia. 



I have species of the genus from the following countries, 

 viz. : — 



One species from North America [sexmaculata, Er.) . 

 Two „ Mexico. 



One „ Columbia {confluent a, 'Er.) 



One „ the Amazons (Santarem). 



One „ Ega. 



One „ Old Calabar {hinotataj infrk). 



One „ the East Indies. 



Five „ Borneo, the Philippine Islands, Morty, 



Flores, Cambodia, &c. 



That from Old Calabar is more like the species from the Indo- 

 Malayan district than those from America, being smaller and 

 rounder, but in facies and all the essential characters of the 

 genus corresponds with them. 



Prometopia binotata. 



Rotundato-ovalis, nitida, leviter punctata, 

 brunnea; elytris singulis disco prope su- 

 turam leviter rufo-notatis. -r 



Long. 1 j lin., lat. 1 lin. i 



Roundish-oval, shining, finely punctate, 

 dark chestnut-brown, with the margins trans- 

 lucent and reddish, and a pale, rather large, ill-defined, oblong 

 reddish spot on the disk of each elytron reaching nearly to 

 the suture; head not so shining, and rather more roughly 

 punctate than the rest. Mandibles bidentate. Labrum slightly 

 emarginate in the centre, and with two slight, rounded denti- 

 culations on each side. Head rather broad. Prothorax deeply 

 emarginate in front; anterior angles acute; sides rounded, 

 with a flat expanded margin very slightly reflexed ; base with 

 the posterior angles extending back rather further than the 

 middle ; disk smooth and without depressions. Scutellum 

 rather small and transverse. Elytra about twice the length 

 of the thorax; sides slightly expanded, and most so at the
