790 SUPPLEMENT. 
To the localities given, add :—Conomsta ! (Fawvel). 
M. Fauvel informs me that he has seen the type of Belonuchus viridipennis, Baudi, 
and that it is this species, and also that he possesses an example from Colombia. The 
name dejectus, therefore, becomes a synonym. 
ACTOBIUS (p. 457). 
3 (a). Actobius mestus. 
Subparallelus, nitidus, niger, pedibus fuscis; dense punctatus, abdomine omnino densissime subtilissimeque 
punctato. 
Long. 5 millim. 
Hab. Mexico, near the city (Hoge). 
Antenne rather short, a little thicker externally, the penultimate joints each slightly 
transverse ; black, the base fuscous. Head subquadrate, shining black ; rather coarsely 
punctured, with a smooth space along the middle. Thorax rather closely punctate, with 
a smooth space along the middle. FElytra longer than the thorax, closely and finely 
punctate ; black, with a very minute griseous pubescence. Hind body not at all narrowed 
towards the base, extremely densely and scarcely visibly punctured. 
This may be distinguished from all other of our species by the minute, dense punctu- 
ation of the hind body. The two examples we have received are, I think, of the female 
sex, though they have the front feet distinctly dilated. 
Actobius politus (p. 461). 
To the locality given, add :—Guatrma.a, Coatepeque (Champion). 
9 (4). Actobius adustus, 
Angustus, elongatus, parce punctatus et pubescens, nitidulus ; capite, pectore, elytris ex parte majore abdominis- 
que versus apicem nigris, prothorace abdomineque basi rufis, antennarum basi, elytrorum apice pedibusque 
pallide flavis. 
Long. 5 millim. 
Hab. Mexico, La Noria in Sinaloa, Tehuantepec (H6ge). 
A distinct species, of elongate slender form, in colour similar to A. pol?tus. Antenne 
elongate ; blackish, with the basal joints pale yellow. Palpi and mandibles yellow. Head 
elongate and narrow, oblong-oval, black, very sparingly punctured. ‘Thorax red, elongate, 
and slender, much narrower than the elytra, at the sides sparingly punctured. Elytra 
longer than the thorax, very sparingly punctured ; blackish, the hind margin broadly pale 
yellow. Hind body with coarse punctuation at the extreme base of each one of the 
basal four segments, these segments red, more or less infuscate ; the penultimate segment 
black, with yellow margin; the terminal segment black, but yellow at the extreme base. 
The male has a feeble dilatation of the front feet, and a slight emargination on the hind 
margin of the last ventral ring.
