We have received about twenty specimens of this extremely variable species, all but 
three of which are from Mexico: of .these, six are black; two are black, with the 
thorax rufous; two are black, with the head and thorax rufous; two are black, with 
the disc of the elytra (and the sides of the thorax also in one specimen) partly rufous ; 
five have the thorax and elytra flavo-testaceous or stramineous, the former broadly 
marked with black on the anterior half of the disc and the latter with the sutural and 
lateral margins and the base black; one (from Chiriqui) has the thorax and elytra 
entirely stramineous ; two are rufous, with the base or apex of the elytra black. The 
anterior coxee are narrowly separated by the prosternum ; the head is almost smooth, 
with the vertex only moderately raised ; the second joint of the hind tarsi is a little 
widened, not or very little more than half the length of the third. 
_ The representatives in the Sallé collection are separated into five species. Iam 
indebted to Dr. Horn for an example of #. limbata for comparison. We figure four 
specimens, all from Mexico.

We have received four female specimens of an Emenadia from Mexico agreeing very 
well with Gerstacker’s description of H. discicollis1, and there is also a Mexican 
example of the same species in the British Museum. In three of these the elytra are 
black with a slight bluish tint in certain lights, and the thorax is rufous or reddish- 
testaceous with the disc to a variable extent black; one (from Sturm’s collection) is 
reddish-testaceous above and beneath, with the apices of the elytra black ; one (in the
