LITOCHRUS. 263 
the localities of the undescribed species he knew; while the wide range he assigns to 
it makes one suspect that he may have included more than one genus under it; he 
also omits to state whether he took the characters from one of the described species 
or from a nondescript form. Under these circumstances the genus must be restricted 
to such insects as agree strictly with his description of the tarsal structure. And 
I accept therefore as typical of it the forms from Arabia and Egypt alluded to by 
Wollaston ?. 
The three species I assign to this genus are each represented by a single example 
only, so that I have not been able to examine them very thoroughly—they are 
extremely different in size and appearance. The first of these resembles a Litolibrus, 
but differs therefrom in having the hind tarsi evidently 4-jointed, instead of apparently 
8-jointed, the basal joint being very long in Zitochrus, while it is very short and 
indistinct in Litolibrus. This species also agrees sufficiently with the Eastern form in 
the structure of the breast, so that the two may be placed together at present, though 
I have great doubt whether they will prove to be really congeneric. Litochrus reversus, 
the second species, is apparently truly congeneric with the Eastern type of the genus. 
The third species I have not ventured to describe ; it is the most minute Phalacrid 
yet discovered. 
1. Litochrus globulus, sp. n. (Tab. VIII. fig. 4.) 
Rotundato-ovalis, valde convexus, piceus, capite prothoraceque nigris, pedibus rufis, elytris sanguineis, anten- 
narum basi testacea, clava nigra; elytris subtilissime transversim aciculatis, stria suturali sat profunda 
posterius munitis. 
Long. 3 millim. 
Hab. Panama, Volcan de Chiriqui between 2500 and 4000 feet (Champion). 
Antenne with the club elongate, black, the tenth joint nearly as long as broad, the 
eleventh joint a little longer. Thorax distinctly lobed in the middle behind, not mar- 
gined. Elytra of a dark red colour, very shining, without any punctures or striz 
other than the sutural stria, but with some very fine transverse scratches ; the sutural 
stria extends about halfway to the front. Unique. 
9. Litochrus reversus, sp. n. 
Ovalis, sat convexus, rufo-testaceus, supra niger, nitidus, elytris strigulis transversis subtilibus. 
Long. 23 millim. 
Hab. Guatemata, San Gerdnimo (Champion). 
Antenne yellow, with large, loosely-articulated club. Thorax lobed in the middle at 
the base, but not margined. Elytra with very fine short transverse aciculations, and 
with a sutural stria, this latter placed very close to the suture at the apex but diverging 
in front; the transverse aciculations become obsolete on the apical part, but some
