BABIA. 83 
behind and extending downwards a little distance along the lateral margin. In 
B. distinguenda the head is either impunctate or extremely minutely punctured; the 
antenne are dentate within from the fifth joint ; the thorax is at least twice as broad as 
long (but agrees in shape with that of B. quadriguttata) ; and the elytra have so many 
extra punctures placed between the more regular strie that the latter are difficult to 
define, all the punctures being of nearly equal size, and also a shallow (but distinct) 
transverse depression below the base. In the Sallé collection this species bears the 
name of #. pudica, Lac., with which I cannot identify it; Lacordaire says (as above 
remarked) that the humeral spot commences below (“sous ”’) the shoulder, and that 
the punctuation of the elytra is scarcely visible, while, on the contrary, in the present 
species it is more strongly impressed than usual. The fifteen specimens received from 
the above localities agree very nearly with each other; in all, the humeral spot is 
transversely-subquadrate in shape (extending to the basal and lateral, but not to the 
sutural, margins), and its posterior margin concave. 
4 (s). Babia amplicollis. 
Babia amplicollis, Deyr. in litt.; Gemm. & Harold, Cat. Col. xii. p. 32987. 
Oblong, widened posteriorly, black; thorax finely punctured, the sides narrowly flattened ; elytra finely 
punctate-striate, a quadrate humeral and a round apical spot, flavous. 
Length 2 lines.

B. amplicollis although closely allied to B. guadriguttata seems to differ sufficiently 
to justify its separation. It is much larger and more widened posteriorly. The thorax 
is strongly transverse, and has a narrow but distinctly flattened and much rounded 
lateral margin (which is not the case in PB. quadriguttata); and its surface is very 
closely (though finely) punctured. The elytra have their anterior spots nearly square 
(that is, their posterior margin, instead of being rounded, is slightly concave or 
straight), the strize distinct, and between the first row and the suture a number of 
irregularly arranged punctures. The specimens contained in the Sallé collection are 
labelled as above ; another, formerly in the collection of Sturm, is labelled B. consen- 
tanea. 
4 (c). Babia parvula. 
Obscure fulvous below ; above black; head punctured near the eyes; thorax extremely finely punctured ; 
elytra widened towards the middle, strongly punctate-striate, the interstices minutely punctured, a 
subquadrate spot at the base of each, and the apex, rufous. 
Length 1 line.

This very small species also seems to be closely allied to B. quadriguttata, but differs 
from it in several particulars. The general shape of B. parvula is ovate and widened
