This insect closely resembles the Mexican L. TU(jipc7inis 

 but differs fioni it by the absence of hair upon the pygidium 

 and propygidium, by the peculiar depression upon the 

 pygidium of the female and also by tlie form of the claws. 

 An undescribed species from Trinidad in the Biitish 

 Museum is still more closely related and is described at 

 the end of this paper in order that the two may be 

 differentiated. 



L. 2^atcns was attracted in numbers to light at night.

 Kufo-castanea, fulvo-pubescens, omnino crebre punctata ; capite 

 parvo, fusco, rugoso-punctato, fronte setoso, clypeo hand emarginato ; 

 prothorace rufo, nitido, lateribus subangulatim dilatatis ; elytris vix 

 pruinosis, cum scutello crebre punctatis, setis nonnullis longibus ; 

 pygidio triangulari, nitido, grosse punctato, setis brevibus erectis 

 parce vestito ; corpore subtus parce, pectore densius, fulvo-piloso ;

This is apparently very similar to Zachnosterna nitidi- 

 collis, Bl., described from Southern Brazil, which is however 

 according to the author somewhat sericeous and with a 

 clothing of fine hairs upon the elytra. The insects before 

 me are merely slightly pruinose upon the abdomen and 

 elytra, and the hairy clothing is not perceptible upon the 

 greater part of the elytra, although fairly thick upon the 

 rest of the body. Had not Blanchard's species been re- 

 corded from so distant a region I should have had more 

 he -itation in separating the present one. 



A number of s{)eciMiens were found beneath decaying 

 leaves at (Jliatcaubelais.
