Coleopterous Suhfamih/ Dynastiiia?. 175 



J fob. Brazil : Ega. 



Two males and a female were collected by H. W. Bates. 

 It is a pretty and eonspicnons species, recalling by its 

 colouring and superficial appearance one of the Erotylidse, 

 or the similarly decorated Carabidie of the genus Z?a, which 

 inhabit the same region. The body and logs are of a brick- 

 red colour, except the elytra, which are bright yellow and 

 each decorated with four spots, of which the two anterior 

 and the large median one are mahogany-red encircled by 

 black.

Hab. Peru : Nauta. 



This peculiar and beautiful species is described from a 

 single specimen taken long ago by Degand at Nauta on the 

 Upper Amazons. It is a female and it is possible that the 

 strongly contrasting opaque apical part of the elytra is a 

 feature of that sex alone. I liave described a similar, but 

 much less developed, condition in the female of the West 

 African Ruteloryctes fristis, and in an allied group the same 

 sexual pbenomenon appears in the Indian Anomala rugosa, 

 Arrow. This peculiar surface distinguishes it immediately 

 from all other known species of Cyclocephala, but its colouring 

 is no less distinctive. It is yellow beneath and red-brown 

 above, with broad lateral borders to the pronotum, the 

 scutellum and a large round spot about the middle of each 

 elytron are of a bright orange colour and the spots are broadly 

 ringed with black.
