314 APPENDIX. NEPIDJ3. 



Length excl. appendages 20-26 millim. ; length of appendages 

 17-20 millim.; breadth of pronotum at base 4-8-6 millim. 



Hob, Bombay (fide Montandon); Bengal (Coll. Dist.). 



This species is to be recognized by its elongate and subparallel 

 form, and as regards the other species here enumerated by the 

 distinctly conical tubercle to the prosternum.

I formerly included this species as a synonym of L. maculatus, 

 Fabr., thus following the decision of Stll (supra).* Dr. Montandon 

 has, however, recently examined Guerin's types contained in the 

 Zoological Museum of Naples and states that it is distinct from 

 maculatus, Fabr., from which it differs in the following particulars. 

 The strong acute tubercle situate on the anterior area of the 

 prosternum, whereas that area is entirely straight and non- 

 tuberculous in L. maculatus; also by the abdominal appendices 

 being proportionately larger, and by the tooth at the base of the 

 anterior femora being more obtusely rounded. In size and other 

 respects it evidently represents maculatus. 



Hob. Bengal (fide Guerin). Madras ; Pondichery. Ceylon. 

 Burma (fide Montandon). Malacca. Seychelles ; Mahe (fide 

 Montandon). 



Laccotrephes griseus, Guer., must therefore now be regarded as 

 a distinct species. Bombay specimens in my collection are un- 

 doubtedly L. maculatus as are also examples from Lobha. It 

 also occurs at Calcutta, where it is very much scarcer than 

 L. griseus. 



Geuus BORBOROPHYES. 



Borborophyes, Stal, Ofv. Vet.-Ak. Fork. 1870, p. 706. 



Type, B. mayri, Stal, from the Philippines. 



Distribution. India; Philippines. 



' Body oblongly-ovate, depressed ; pronotum equally long as 

 anteriorly broad, behind middle turned backwardly, moderately 

 ampliate, disk furnished with two longitudinal rugosities, pos- 

 teriorly transversely impressed, anterior margin medially behind 

 head profoundly sinuate, posterior margin broadly moderately 



* Dr. Montandon has given ine the credit of this synonymy instead of 

 quoting StSl as its author.
