HELLERIELLCA.—TIMORUS., 33 
legs short and stout, the posterior femora not reaching beyond the second ventral suture; femora very 
stout, clavate, deeply sulcate at the apex beneath, and each armed with a short triangular tooth; third 
tarsal joint short, broadly bilobed, the claws very small. 
This genus includes a remarkable form from Eastern Mexico, chiefly characterized 
by its elongate cylindrical prothorax, narrowly separated intermediate cox, and short 
stout legs. It is not very closely related to any of the genera enumerated or described 
by Dr. Heller, after whom I have dedicated it. 
1. Helleriella longicollis, sp.n. (Tab. IT. figg. 28, 28 a.) 
Elongate, flattened above, moderately convex beneath, black, the rostrum (except at the base) and antennse 
ferruginous; thickly clothed with small narrow scales, those on the under surface and on the first elytral 
fascia coarser ; the head between the eyes, the prothorax with the sides, base, and apex, and a line down 
the middle, and the elytra with the base and suture narrowly, a small spot at the apex, and a sinuous, 
interrupted post-median fascia, whitish, with a few fulvous scales intermixed, each elytron also with a 
broad, curved, fulvous fascia below the base, the rest of the upper surface blackish, the legs and under 
surface entirely whitish. Head rugulosely punctate ; rostrum sparsely punctate and shining, the dilated 
basal portion rugulose and squamose. Prothorax longer than broad, feebly constricted at the apex ; 
closely punctate. FElytra a little wider than the prothorax, and less than twice its length, conjointly 
rounded at the apex; densely rugulose, finely and shallowly punctate-striate. Ventral segment 1 
slightly depressed down the middle. 
Length 43, breadth 14 millim. (¢?) 
Hab. Mexico, Vera Cruz (Sailé). 
One specimen.

Bull. Soe. Ent. Fr. 1879, p. Ixxi; Heller, Abhandl. Mus. Dresd. no. 11, pp. 4, 60. 
This genus includes a few conspicuous Tropical-American forms, one of which has 
been recorded from Mexico; the ljast-mentioned locality, however, requires confirma- 
tion. Zimorus is related to Copturus, differing from it in the relative lengths of the 
first two joints of the funiculus, the coarse vestiture, &c.

Two specimens of a Jimorus in the Vienna Museum (kindly communicated by Custos 
L. Ganglbauer), one labelled “ Brazil” and the other ‘“ Mexico,” seem to belong to 
Rosenschoeld’s species, though they differ from Lacordaire’s figure of 7. suturalis, and 
from the examples of that insect in the British Museum, in having the elytra more 
strongly tuberculate. We take the opportunity of figuring the “ Mexican” specimen.
