GERAUS. 
23. Gereeus crucifer, sp. n. (Tab. XV. figg. 6, 64, 3.) 
Centrinus crucifer, Pilate in litt. 
Elliptic, black ; densely clothed above and beneath with rather large whitish or brownish-white scales, the 
prothorax with two vitts on the disc (sometimes confluent and sometimes each divided into two spots), 
and often a small spot on each side anteriorly, the scutellum, and the elytra each with a large subquadrate 
patch on the disc before the middle (extending inwards to the first stria) and a smaller patch towards the 
apex, these markings usually connected along the sides, fuscous. Head closely punctate; rostrum 
strongly arcuate, longer than the head and prothorax, moderately stout, rather closely punctate, smoother 
in the 9, the antenne inserted at about the middle, the antennal club ovate. Prothorax broader than 
long, arcuately narrowing from the base, constricted in front; very densely punctate, and sometimes 
with a smooth raised median line. Elytra rounded-triangular ; finely punctate-striate, the interstices 
densely punctate. Beneath densely punctate. Prosternum unimpressed behind the transverse subapical 
groove. Anterior cox separated by fully their own width. 
$. Prosternum armed with two compressed conical tubercles, and also excavate between them ; first ventral 
segment depressed down the middle. 
Length 3-34, breadth 14-1,%, millim. (¢ 9.)

Hab. Mexico, Yucatan (Dupont, in Mus. Brit.), Temax in N. Yucatan (Gauwmer). 
Sent us in numbers by Mr. Gaumer, but most of the specimens are in bad condition. 
The markings of the upper surface vary according to the predominance of the whitish 
or fuscous scales, which are rather large and closely placed, both above and beneath. 
The prosternal tubercles are small. Centrinus bicoloratus, Boh., from Brazil, is an 
allied form. G. bicruciatus (infra), too, is very like the present species, but it has 
an unarmed prosternum in the male. 
24. Gereeus octomaculatus, sp. n. (Tab. XV. figg. 7, 7a, 2.) 
Oblong-elliptic, flattened above, black; thickly clothed with brownish-white scales, the prothorax with two 
large spots on the disc at the base and a similar spot at the sides before the middle, the scutellum, and 
the elytra each with a broad transverse fascia on the disc before the middle extending up the side to the 
base and a subtriangular patch just before the apex (these markings extending inward to the first stria), 
black. Head finely punctate, transversely depressed between the eyes; rostrum strongly arcuate, 
-. rather stout, thickly punctate at the base, the apical half much smoother. Prothorax densely, finely 
punctate, with a smoother raised median line. LElytra finely punctate-striate, the interstices densely 
punctate. Beneath densely punctate. Prosternum unimpressed behind the transverse subapical groove. 
Anterior coxee separated by about their own width. 
- Length 4, breadth 2 millim. (2.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé). 
One female. ‘This is the Vera Cruz form of the Yucatan G. crucifer, differing from 
that insect in its more elongate shape and in the disposition of the dark spots on the 
prothorax, these being equal in size—two on the disc at the base and one on each side 
before the middle. The prosternum is doubtless spined in the male.
