HEMIPEPLUS.—LZMOPHLEUS. 513 
Inopeplus is about as little as can be. It should be added that Hemipeplus was 
originally assigned to Cucujide because it was supposed that the female, when 
discovered, would prove to have five joints on the hind feet. The contrary has, 
however, proved to be the case. 
The genus is distributed from the Southern States of North America to Brazil.

LAMOPHLCUS. 
Lemophieus, Castelnau, Hist. Nat. Ins. Col. ii. p. 385 (1840). 
This genus was established by Castelnau for a single European species, Cucujus 
monilis, Fabr.; the characters he assigned to it have no distinctive importance, but the 
species in question must remain the type of the genus. Our ZL. suturalis and L. distin- 
guendus are strictly congeneric with Z. monilis (now called L. denticulatus, Preyssl.). 
The difficulties connected with the study of Lwmophilaus are well known, and are 
increased by the fact that many of the species are extremely rare. At present upwards 
of 100 species are assigned to it. I have, however, here removed from Lemophlous 
all those forms that have the anterior acetabula closed, and have established various 
genera for them. This still leaves the genus a composite one, and I have endeavoured 
to make it somewhat more natural by proposing Rhabdophiwus for a few forms with 
the hind cox unusually approximated, and Rhinophleus for a few other species in 
which the front of the head is slightly prolonged anterior to the antennal insertion. 
After doing this, I find that there are forty species of our fauna still left in 
Lemophieus, and I regret that I am not able to arrange them in groups to facilitate 
their determination. 
{am much indebted to M. A. Grouvelle for examining a series of our Lemophlai, 
and favouring me with the names of those known to him. Hitherto only about nine 
species of Lamophleus have been recorded from our region. Of these L. teapensis, 
L. pallentipennis, and L. minusculus were not recognized by M. Grouvelle amongst our 
series, and I have removed L. capito, L. gundlachi, and L. costatus to other genera. 
I now add thirty-one new species, as well as three or’ four South-American forms, to 
the Central-American fauna.
