specimens standing under the name M. pulcarvwm in the 
British Museum, probably belonging to two species, both 
very different from the Guatemalan type, one of which 
is doubtless the insect M. Pic describes. He also charac-

This genus is mainly characterised by the very long, 
parallel-sided, flattened, 3-jointed antennal club, the 
closely articulated apical two joints of which united are 
about as long as the elongate preceding joint, the club itself 
being sometimes much wider in the male than in the female. 
The metasternum is notched in front, leaving the tips of 
the antennae exposed when these organs are retracted into 
the meso- and metasternal cavities. The species are 
numerous in Central America and nine are recognised by 
Fall from the United States or Lower California. Pic, in 
his “‘ Catalogue of Anobiidae,” 1912, p. 64, sinks Hupactus, 
Lec., Hutheca, Kies., and Thaptor, Gorh., under Calym- 
maderus, Sol.; but in this I cannot follow him, the last 
named Chilian genus having a very prominent hood-like 
anterior prolongation to the thorax. Thaptor (and not 
Itoolius), Gorh., is also sunk by Fall as synonymous with 
Eupactus, but they are here retained as distinct. The type 
of Hupactus, HL. nitidus, Lec., is a small, oblong-oval, shin- 
ing, glabrous insect; that of Thaptor, T. pupatus, Gorh., a 
large, subfusiform, densely pubescent insect (approaching 
Calymmaderus in shape), with a single submarginal stria to 
the elytra, and a dense double system of punctuation, above 
and beneath. 
The following table will assist in the identification of the
