articulation undoubtedly evident. The species are, moreover, peculiar in the elytra 
having no trace of even a sutural stria. 
The elongate metatarsus is very remarkable, it being six times as long as the apparent 
second (truly third) joint. The elongation of this part of the foot renders it possible 
that the species might be referred to Litochrus; but if the long metatarsus be considered 
as one joint, there is then a joint less in the foot than there is in Litochrus, so that 
the two genera are very distinct, though the structure of the breast is similar in 
both. 
1. Kulitrus estriatus, sp. n. (Tab. VII. fig. 23.) 
Ovalis, sat convexus, piceus, supra nigerrimus ; elytris estriatis, punctis irregularibus, subobsoletis, subtrans- 
versis, anterius desinentibus. 
Long. vix 4 millim. 
Hab. Nicaracva, Chontales (Janson) ; Panama, Bugaba (Champion). 
Antenne dark red, thick ; club broad, loosely articulated, the terminal joint but little 
longer than the tenth, obtuse. Head very broad. Thorax with a short lobe in front 
of the scutellum, but not margined. Scutellum small. Elytra without distinct basal 
margin. 
Four examples of this species have been received, three of them in a very mutilated 
condition. 
2. Eulitrus anisotomus, sp. n. 
Ovalis, piceus, nitidus, antennis pedibusque testaceis; elytris rufis, marginibus nigris, punctis subtransversis 
obsoletis. 
Long. 23 millim. 
Hab. Brivish Honpuras, R. Hondo (Blancaneauz). 
This insect resembles Acylomus aciculatus, with which it cannot be confounded, 
however, if the absence of a sutural stria be noticed. 
From Lulitrus estriatus it differs by the smaller size and the more dilute colour. 
LITOLIBRUS, gen. nov. 
Corpus hemisphericum. Prosternum parvum, muticum. Metasternum parum prominens, inter coxas haud 
productum. Tarsi posteriores elongati, articulo primo brevi, secundo valde elongato, cum primo oblique 
articulato et consolidato. 
This genus has the tarsi formed much as in Hulitrus; but the metasternum is very 
different, and in this respect the genus is one of the lower forms of the family, Eulitrus 
being at the other extremity. 
Litolibrus contains the most remarkable Phalacrids yet discovered, and some of the 
species are beautifully coloured, but these are apparently all very rare. Although the
