down the centre of the crown and one on each side, and the 
lower part of the face, tawny. Antennz as long as the body, 
black, apex obscurely rufescent; apical half of the fourth and 
nearly the whole of the fifth jomt clear tawny yellow. Thorax 
elongated, lateral tubercle small, conical ; surface coarsely punc- 
tured and tubercular, black; sides each with a broad golden- 
fulvous vitta. Scutellum black. Elytra elongated, a little 
dilated at the apex ; surface setose, closely punctured, partly in 
rows, black ; lateral edges near the base obscurely rufescent, and 
an indistinct streak from the shoulder down each side dull 
tawny. Body beneath clothed with silvery-grey tomentum. 
Legs black; femora at the base rufescent. 
Ega. 
The preceding series of species, mimicking respectively various 
types of Coleoptera, do not exhaust the variety of dress which 
the Callie put on. I have a small species in my collection, 
from Rio Janeiro, which presents the style of coloration of cer- 
tain species of Lampyride*. 
Genus PRETILIA, noy. gen. 
Closely allied to Cala, but differs in the thorax being un- 
armed on the sides. This part of the body is short, convex, and 
rounded, the sides being tumid instead of having the distinct 
conical tubercle. The eyes are short and convex, their reniform 
undivided shape distinguishing the species from the Tetraopine, 
to which they are allied by the form of the thorax. The body is 
linear and setose. The antenne are filiform and longer than the 
body in both sexes ; the third joint is much elongated, and half 
as long again as the fourth, the remainder being filiform and 
slender to the apex. The pro- and meso-sterna are both very 
narrow. The legs are moderately elongated, and the tarsal 
claws have a large tooth at the base. 
I am indebted to Mr. Alexander Fry for pointing out the chief 
distinguishing characters of this genus.
