Apparently very rare ; T have only seen two specimens, one in Salle's collection, the 

 other in that of Crotch. The punctures in the elytral striae are for the most part only 

 indicated by fuscous dots in eight series, the series being continued to the apex ; it is 

 only at the base and in a few instances that they are impressed, the surface of the 

 elytra being quite even. The figure is taken from the specimen from Oaxaca. 



2. Lybas carbunculus. (Tab. IV. fig. 16.) 



Lybas carbunculus, Lac. Monogr. Erotyl. p. 238 \ 



Hab. Mexico, Toxpam (Sallti), Tabasco *, Yucatan l ; Guatemala, Senahu in Vera 

 Paz (Champion) ; Panama, Bugaba (Champion). 



Var. ? Major (7 millim.), minus laete sanguineus, prothorace utrinque punctis duobus magnis impressis. 



Hab. Guatemala, Zapote (Champion). 



A species usually distinguished by its medium size (vix 6 millim.), dark blood-red 

 colour, and very shining varnished appearance. The sides of the metasternum have a 

 few obsolete largish punctures, the rest of the underside being smooth. Metasternal 

 and abdominal, plicate, raised lines are present. The antennae are black, with two (in 

 the Mexican) or three (in the Guatemalan specimens) joints red at the base. In the 

 larger specimen from Zapote I see very little difference, except that two joints at the 

 base of the antennae are red, and that the general colour is lighter and less lucid. 



3. Lybas interpunctatus. 



Breviter ovatus, lsete castaneus, lucidus ; antennis nigris, articulis tribus basi runs ; elytris punctato-striatis, 

 punctis baud magnis, interstitiis crebre et distincte punctulatis. Long. 6| millim. 



Hab. Mexico, Cerro de Plumas (Hbge). 



Closely allied to L. carbunculus, from which it differs in its slightly larger size, 

 rather broader form, and, especially, in the elytra being (under a strong lens) evidently 

 punctured all over, the fine punctures being placed longitudinally between the serial 

 ones as well as in the interstices. The head and thorax are very shining, but are 

 punctate though extremely finely so. The serial punctures on the elytra are small and 

 obsolete superficially, but distinct as fuscous spots under the surface. The underside 

 is very smooth and shining, with only a few obsolete but large flat punctures on the 

 sides of the metasternum. This species and its allies have frequently two or more 

 quite symmetrical impressions upon the thorax ; but the impressions are not constant 

 and of no use for characters— thus, one specimen of L. interpunctatus exhibits two 

 oblique depressions near the centre of the thorax, while the other is quite free from 

 them. 



4. Lybas anisotomoides. 



Concinn© ovatus, convexus, pernitidus, saturate rufo-brunneus ; antennis nigris, articulis tribus basi runs ; 

 elytris punetulato-striatis. Long. 5 millim.
