PSEU DOBARIS. 459 
Sent us in numbers by the late C. F. Hége from Ventanas. This insect is nearly 
related to P. luctuosa, Casey, from Florida *; but it is a little less elongate, and has 
the elytra relatively shorter and more narrowed towards the apex, and the interstices 
are subcarinate on the apical declivity. ‘The prothorax is very coarsely, closely 
punctate (except along the smooth median line, which is often wholly wanting in some 
specimens from the same localities), and the elytra have a row of coarse transverse 
punctures along each interstice, those on 2, 3, 5, 7, and 9 each bearing a rather long, 
decumbent, easily-abraded seta, 38 with a few white scales at the base. ‘The rostrum 
of the male is rather coarsely punctate, that of the female being smoother and flatter 
at the tip. The tarsal claws can scarcely be described as connate at the base in the 
type kindly communicated by Signor Solari. The length varies from 23-44, and the 
breadth from 14-2545 mm.

$. Prosternum in large, fully-developed examples more or less tumid in front of the anterior coxex (the 
median sulcus thus becoming wider and shallower, or obsolete posteriorly), in some specimens flattened 
and with the median sulcus deep and parallel-sided; metasternum and first ventral segment broadly 
hollowed down the middle; pygidium tumid in the centre. 
Q. Rostrum more sparsely punctate than in the ¢; pygidium flattened, sometimes carinate down the 
middle.

A very elongate, shining, black form with a conspicuous albo-squamose spot on the 
basally widened portion of the third elytral interstice, of which I have seen numerous 
males (including the type) and seven females. ‘The males vary in the development of 
the prosternum as above described, and in fresh specimens the femora (which are 
scarcely sulcate beneath) and tibie are more or less hairy. ‘The females vary 
enormously in size, some of them (?=var. 8 of Boheman) being very small and 
subcylindrical. ‘lhe specimens before me measure: length 43-84, breadth 14-53} mm.

* The N.-American Baridius anthracinus, Boh, (the type, ¢, of which I have seen), is not Synonymous 
with P. luctuosa as Casey supposed, but = Aulobaris ibis, Lec., a specimen of which from Florida is 
pefore me. It has a long second joint to the funiculus.
