species, as in the female, and sometimes covered by the apices of the elytra. 
B. fervida, B. fluctuosa, &c. the strongly unguiculate tibiz are more or less dentate 
at the inner apical angle in the female, this tooth being obsolete in the male. 
S.-American Baridius ferrugo, B. wnescens, B. ater, B. erubescens, and B. smaragdinus, 
Kirsch, belong to Baris as here understood *. 
The following table will assist in the identification of the Central-American species ; 
some of those numbered 22-30, however, still require further investigation, several of 
them having been described by Boheman or Solari from single specimens only :— 
a. Tibie (except in B. occidua) more or less dilated or toothed at the outer 
apical angle (appearing hollowed on their outer edge). 
a’. Rostrum with two undulate longitudinal ridges, and also hairy, towards 
the apex beneath. Frontal depression shallow. Scutellum strongly 
transverse. Body black or piceous. 
a’, Elytral interstices narrowly subcostate on each side, coarsely scriate- 
punctatedown the middle. . . . 2... 2... 
6°, Elytral interstices simply seriate-punctate - + ss 
6’. Rostrum without distinct ridges beneath; frontal depression sharply 
defined. 
c’. Body black or piceous ; elytra even, the interstices uniseriate-punctate : 
length under 3 mm. . . a coe 2 eg ee 
d’, Body neous ; elytra uneven, the interstices more closely punctate : 
length 6 mm. a 
6. Tibiz not or scarcely dilated at the outer apical angle (almost straight on 
aad outer edge) ; rostrum without ridges beneath. 
= Fareal claws long; pygidium large or moderately large. 
. Prosternum unimpressed or indefinitely sulcate down the middle; 
prothorax not tubulate in front. 
a*, Prothorax gibbous; scutellum rather large, transverse-oval ; rostrum 
abruptly bent at about the middle; antennal club glabrous at 
the extreme base only; frontal depression very shallow: species 
large, metallic, coarsely punctured . . 
b°. Prothorax feebly convex; frontal depression sharply detined. 
a* Scutellum transverse, subquadrate, or rounded, small. 
a’. Body black or piceous, sometimes with a faint zeneous lustre. 
a‘. Elytra strongly undulate, deeply sulcate, and _ coarsely 
punctured . . 
b°. Elytra more even, less coarsely punctured 
6°. Body in part rufescent, the elytra almost bare a 
c’. Body more or less metallic, the elytra in some of the species 
(B. aspera, B. setosella, B. inopina) closely setulose

* It may be noted here that Baridius collaris, Boh., belongs to Loboderinus, Solari, whose two species, 
clavatus and basalis, are probably ¢ and @ respectively of Boheman’s insect. 
~ B. metallica, B. metallescens, B. catenulata, and B. viridana, Boh., and B. interpunctata, Germ., are allied 
S.-American forms.
