TETRAONYX. 391

In Mr. F. Bates’s collection there is a Mexican specimen of a Tetraonyx agreeing 
perfectly with Klug’s excellent figure of 7. dimaculatus; and this specimen has been 
so named by Haag. IT. bimaculatus chiefly differs from 7’. maculatus by having the 
basal black spot of the elytra extending to the humeri, and the transverse flavous space 
behind this spot broader; the head is black. The basal joint of the anterior tarsi is 
very stout, and dilated on the inner side, in the male. TZ. guadrimaculatus (Fabr.), 
from the Southern States and the Antilles, is an allied species; it has the thorax 
closely punctured.

We have received nine specimens of a Tetraonyx agreeing very well with Haag’s 
definition of 7. maculatus, Casteln. A small species, of a flavous or flavo-testaceous 
colour; the elytra each with two very large black spots—one basal, not quite reaching 
the suture and more or less-excised near the shoulders in front, the other apical, the 
latter confluent with the one on the opposite elytron; the antenne, the apices of the 
femora, the tibie, and tarsi black; the underside reddish-testaceous. ‘The head is 
sometimes partly brownish, and the thorax often has a piceous or brownish patch, or 
two small spots placed transversely, on the middle of the disc. Haag appears to have 
examined some of Sallé’s Mexican and Nicaraguan examples; but the only locality 
mentioned by him ? is Brazil. 
In Sallé’s collection the specimens with the thorax immaculate are labelled 7’. macu- 
latus and those with the thorax spotted 7. maculicollis. 'The basal joint of the anterior 
tarsi is slightly widened in the male. 
10. Tetraonyx decipiens.

Hab. Mexico (coll. Haag"). 
‘«‘ Subelongate, rufous; the antenne, the scutellum in the middle, the sides and hind 
margin of the mesosternum (? hind coxe), the apices of the femora, the tibie, and tars! 
blackish; head and thorax shining, the latter strongly transverse, canaliculate, and 
impressed on both sides, sparsely punctured ; elytra opaque, rufous-pilose. Length 9, 
breadth 42 millim.”
