DOMOPTOLIS.—_NEANTHRIBUS. 341 
oblique in position, the head therefore narrowing strongly anteriorly, Antenna with white hairs beneath ; 
third segment nearly twice the length of fourth. Pronotum broader than long, longitudinally plicate on 
disc, with large, very shallow punctures laterally, subreticulate ; angle of carina 90°, basal longitudinal 
carina at practically equal angles with lateral and dorsal carina. LElytra short, hardly at all depressed 
at suture. Pygidium twice and one-half as long as basally broad. 
Length 3 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen, apparently a female. D. championi stands intermediate between 
Gymnognathus and Domoptolis, Jord. (1904). As the latter is based on a single species, 
I abstain from proposing a new genus for the present insect. The antennal cavity is 
as large as in Gymnognathus erna, Jord. (1904). There is no mesial carina on the 
underside of the rostrum. 
XX. NEANTHRIBUS, gen. nov. 
3 @. Rostrum short, with a more or less distinct mesial carina, which is continued on to frons, but is inter- 
rupted at base of rostrum by a punctiform groove. Lye lateral, close to antennal groove, truncate in 
front or very feebly emarginate. Antenna longer in ¢ than in 9; a club of three segments, which 
are hairy underneath in the males. Carina of pronotum basal, being vertically above the true basal edge, 
angle 90° or more, with the tip more or less rounded off, lateral carina extended a little beyond middle ; 
a transverse row of three tufts in middle of pronotum. Llytra as broad as prothorax, cylindrical, not 
depressed, with tufts or pustules, lateral edge often with long hairs. Prosternum very short; fore cox 
well separate, as are mid and hind coxe. Legs short, often villose. 
Type: JV. championt, sp. n. 
Range: America. 
The American insects allied to the European Anthribus albinus form a group 
generically distinct from the Old World representatives of Anthribus. When describing 
in 1904 a number of species of Neanthridus under the generic name Anthribus (Nov. 
Zool. xi. pp. 296-300) I abstained from proposing a new genus for their reception, as 
at that time I had no evidence that these insects could be distinguished generically in 
both sexes from Toxronotus, Lacord., a genus also closely allied to Anthribus and based 
upon a Cuban species, of which I had only two males. As Lacordaire states in the 
diagnosis of Toxonotus—and no subsequent author appears to have corrected the state- 
ment—that the female is devoid of the peculiar spine into which the first tarsal 
segment of the male is produced, I thought it possible that Toxonotus might prove not 
to be generically distinct from Anthribus. On receipt of more material of Toxonotus, 
among which there is an undoubted female, as the sexual organs prove, I find that 
the female has the same tarsal spine as the male, at least in the only species so far 
described, 7. fascicularis, Schoenh. (1833), occurring in Cuba and Florida. Probably 
Lacordaire mistook some species of Neanthribus for the female of 7. fascicularis, 
Neanthribus being also represented in Cuba, according to a specimen in the Tring 
Museum bearing the label “ Cuba.”
