various Central American Coleoptera. 117 
Three species have been referred to this genus, one of 
which, the type, abounds on tamarisks in the Mediter- 
ranean region, the others are American. The 2-jointed 
antennal club, and the 4-jointed tarsi, the anterior pair 
with three joints only in the male, are its chief characters. 
Casey is of opinion that Berginus should be placed near 
Lyctus [cf. Journ. N. York Ent. Soc. vii, p. 129 (1900)]; 
the latter was included in the Bostrychidae by Gorham in 
the ‘ Biologia.” 
*Berginus nagricolor, n. sp. 
Moderately elongate, opaque, black or piceous, the legs some- 
times obscure ferruginous; thickly clothed with short, curled, 
squamiform, cinereous hairs, which are seriately arranged on the 
elytra. Head and thorax very densely, somewhat coarsely punctate ; 
the latter convex, about as long as broad, narrowed anteriorly, the 
sides rounded and finely serrulate, the hind angles distinct; eyes 
convex, small, prominent; antennae barely reaching the base of 
the thorax, joints 1 and 2 stout, 3 narrow, as long as 2, 4~9 short, 
about as broad as long, the two joints of the club (10 and 11) stout. 
Elytra moderately long, considerably wider than the thorax, sub- 
parallel in their basal half; with rows of closely packed rather 
coarse punctures, the interstices narrow, transversely rugose. 
Beneath densely, coarsely, the ventral segments 2-5 more finely, 
punctate. 
Length 14-13 mm. (¢ 2.) 
Hab. GUATEMALA, San Gerénimo, Mirandilla (Champion) ; 
Nicaracua, Chontales (Janson) ; Panama, Tolé (Champion), 
Portobello, Paraiso, Panama city (Schwarz, in U.S. Nat. 
Mus.). 
Apparently a common insect in Central America. From 
B. pumilus, Lec., it may be known by its smaller size, 
more slender build, the non-costate, regularly punctate- 
striate elytra, and the finer vestiture ; and from B. bahamicus, 
Casey, by its black antennae. In the U.S. National 
Museum there is a mutilated example from Brownsville, 
Texas, labelled as having been found in dead cotton bolls, 
that may be referable to this species. Specimens of the 
described American forms have been sent us by the U.S. 
National Museum.t B. bahamicus has been found on 
1 In the British Museum there is a single example (2) of an 
unnamed species related to B. nigricolor, with much larger eyes 
and stouter tarsi; it is from Grahamstown, S. Africa.
