widest just before middle; sides arcuate except near base; lateral 

 depressions deep and irregularly sculptured, but extending only to 

 basal third; midline not canaliculate, but disk depressed just before 

 base; punctures coarse, somewhat elongate, seldom uniting, fre- 

 quently separated longitudinally by less than their length; ground 

 sculpture feeble but not distinctly scaly. Elytron with sutural stria 

 impressed; discal stria not impressed but marked by denser punc- 

 tures sometimes united in short rows; punctures of disk large, 

 elongate, and excavated behind; ground sculpture feeble but not 

 distinctly scaly. Abdominal sternites with fine diagonal carinae at 

 sides. Length, 4i/4 nim. 



Type locality. — Trinidad, Arima-Paria road. 



Types. — Holotype, Museum of Comparative Zoology, collected by 

 Dr. P. J. Darlington. 



Records. — The following is the only record laiown to me : 



Trinidad: Arima (M.C.Z.). 



SpeciTnens cocamined. — ^I have seen only the holotype. 



Remarks. — This species is similar in most respects to insularis but 

 differs markedly in the extent of the pronotal depressions. L. insularis 

 has not yet been found in Trinidad, although it may be expected 

 there. 



I have received no record of the habits of this species.
