Anthicus albicinctus, La ‘Ferté, Monogr. Anthic. p. 111°. 
Anthicus sallei, La Ferté, in litt. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guatemana, Chaco) in the Polo- 
chic valley (Champion); Nicaraaua, Chontales (Janson); Panama, Peha Blanca 
(Champion).—CoLomBia ; VENEZUELA, Cumana}, Caracas, &c. 
In this peculiar little species the thorax has a deep transverse groove extending com- 
pletely across the narrowest part, the anterior portion being globose and the posterior 
portion subparallel; and the elytra have a very deep and large post-basal depression, 
the space in front of this on either side of the suture being much swollen. The 
insect is brownish-black or dark reddish-brown in colour, the elytra with a flavous 
ashy-pubescent transverse fascia occupying the basal depression ; the upper surface is 
very shining, with only a few very widely scattered fine punctures, the punctures each 
bearing a long erect hair; the head is transverse, the eyes rather large; the antenne 
are distinctly thickened outwardly and somewhat clavate, and have the four or five basal 
joints testaceous and the others piceous-brown or black; the legs are piceous or 
brownish, with the tarsi more or less testaceous. ‘The male has the fifth ventral 
segment very deeply triangularly emarginate. 
Our specimens are blacker in colour than those contained in the La Ferté collection, 
in which both sexes are represented. A specimen from Caracas in the La Ferté 
collection is labelled A. sallei, mihi, ined. . 
A. gibbicollis, La Ferté, from Venezuela, is an allied species, not yet received from 
within the limits of our fauna. 
2. Anthicus bituberculatus. (Tab. X. figg. 2; 2a, profile.) 
Anthicus omoplatus, Deyr. in litt. 
Moderately elongate, black or brownish-black, the head, prothorax, and base of the elytra sometimes pitchy- 
red, the elytra with a transverse ashy-pubescent testaceous or yellowish fascia (not reaching the suture and 
sometimes indistinct) occupying the post-basal depression; the entire upper surface very shining and 
furnished with widely scattered long erect hairs. Head nearly as long as broad, rounded at the sides 
behind, shallowly and irregularly punctured and clothed with fine greyish pubescence in front, smooth and 
glabrous posteriorly, the eyes moderately large, the palpi piceous; antenne with the apical four joints 
widened, joints 9-1] wider than 8, 1—4 or 1-5 flavous or testaceous, the rest black; prothorax very much 
narrower than the head, longer than broad, very strongly constricted at the sides behind the middle and 
with a transverse groove extending across the disc in the narrowest part, the anterior portion globose and 
strongly gibbous, the posterior portion very short and not swollen, the base feebly margined, the flanks very 
deeply excavated, the surface with a few fine widely scattered punctures; elytra rather short, widest 
about the middle and narrowing in front, with a very deep transverse post-basal depression, and somewhat 
gibbous behind this, the basal portion on cither side of the suture conically raised in both sexes, the 
humeri prominent, the surface smooth or with irregular rows of fine shallow punctures towards the base ; 
legs piceous or brownish, the tarsi more or less testaceous; fifth ventral segment deeply triangularly 
depressed in the middle behind and the apex emarginate in the male.
