212 MALACODERMATA. 
2. Lyctus prostomoides. 
Oblongus, brunneus ; prothorace subquadrato, postice parum angustato, minute punctato, medio depressiusculo ; 
elytris breviter sericeo-pubescentibus ; capitis fronte transversim impressa, epistomate utrinque ante oculos 
elevatiore. Long. 34—4 millim. 
Hab. Guarema.a, Capetillo, San Gerdnimo, Purula, El Tumbador (Champion); Panama, 
San Lorenzo (Champion). 
Species of Lyctus are usually very variable in size; the present species will probably 
form no exception to this rule, although, of about a dozen specimens collected by Mr. 
Champion, the size only varies about half a millimetre. Its colour is rusty red or rich 
brown; and it is distinguished from other species known to me by the absence of linear 
pubescence, very faint and obsolete strize alone being discoverable on the elytra. ‘The 
ridge in front of the eyes commences at the insertion of the antenne, and in other 
species only forms the tubercle from which they arise. The thorax is very even and 
nearly square, but narrows behind, the sides being very straight ; the central depression 
is wide and shallow, and bifurcate in front. ‘The elytra are less parallel than in some 
species, as they narrow slightly towards their apex ; the pubescence, which is depressed 
and not in series, is yellow. ‘The above description is from specimens from El Tumba- 
dor, where Mr. Champion took eight specimens. 
3. Lyctus griseus. 
Oblongus, nigro-piceus, opacus, dense griseo-pubescens; antennarum articulo ultimo rufo; prothorace haud 
fossulato, subquadrato, angulis posticis obtusiusculis; elytris seriatim pubescentibus, vix puuctatis. 
Long. 13-3 millim. 
Hab. Guatemata, San Gerdénimo, Paraiso (Champion). 
The specimens from San Gerénimo agree in being more densely and coarsely pubescent 
than any species known to me. The two from Paraiso are not.only browner red in 
colour, but seem to have more rigid and sparser hairs in rows on the elytra; one of 
these is a very small example; the smallest of the San Ger6nimo specimens is fully two 
millimetres in length. In these two specimens the antenne and legs are rusty red ; 
but in all the San Gerdnimo ones they are dark with the apical joint clear red. The 
absence of any distinct thoracic fovea is a good character; a central line is sometimes 
indicated in the disposition of the hairs, which are very dense and hide the actual 
surface of the disk. I have little doubt that this is a very distinct species; and possibly 
the Paraiso species is different. 
APATE. 
Apate, Fabricius, Syst. Ent. p. 54 (1775). 
The type of Apate is A. terebrans, Pall., which is taken to be the same as 4. muricata, 
Fabr., the former being found in Africa, the latter in America. With this type we 
must join about a dozen species of middle or large size found in various parts of the
