218 Mr. J. O. Westwood's Descriptions 



this species with Dorcus curvicornis, Latr. in Dej. Cat. from New 

 Holland. The description of that species given by Boisduval, 

 " Faune de I'Oceanie," 2, p. 235 — " Fuscus thorace transverso 

 subpunctato ; elytris punctatis ; mandibuHs exertis, dente crasso 

 armatis ; subtus piceus," is too sh'ght to determine the identity, 

 or even to warrant the retention of Latrielle's name if proved. 

 My insect is not fuscous, the prothorax is as strongly punctured 

 as the head, and I can scarcely think that Latreille would have 

 applied such a name as curvicornis to the species.

Obs. — This species, with L. Cancroides and obtusatus, placed by 

 Dr. Burmeister as the second section of the genus JEgiis, belong, 

 in fact, to a different sub-family, having the mando of the maxillae 

 in both sexes armed with a corneous hook. The mandible and 

 maxilla of this sex in L. reticulatus are represented in our 

 Plate XII. figs. 9 a and 9 b. It differs from the three preceding 

 species, not only in its geographical position, but also in the 

 patches of pile on the upper svn-face of the body,
