34 Mr. C. O. Waterhouse on new Pectinicorn Coleoptera. 



Hah. Assam, Munipur, 6000 feet (Win. Dohertg, Esq.). 

 Coll. A. Fry. 



This species is nearest to L. maculifemoratus. The largest 

 form is quite unlike any other species, and the long deflexed 

 mandibles somewhat resemble those of Cladognathus inclina- 

 tus, having on the inner side about eighteen or twenty small 

 teeth, with a rather larger one at the middle. On the top of 

 the head are three large erect laminae, one in front, as in L. 

 maculrfernoratus, but larger and arched at the top, and two 

 others (representing the usual posterior crest), wider than the 

 anlerior one, slightly oblique, arched at the top, with the 

 outer angle produced. 



The smaller male closely resembles L. Westermanni, but is 

 distinguished by the mandibles having two teeth in front of 

 the middle (instead of one) before the apical fork. 



The female resembles that of L. maculifemoratus in its 

 elongate narrow form, but is not quite so long, has the thorax 

 more parallel at the middle of the sides, more strongly sinuate 

 before the posterior angles, and with the disk almost smooth. 

 The anterior tibiae, are nearly as in L. maculrfernoratus, with 

 three or four teeth besides the terminal one, and with the apex 

 not very much produced. 



I am indebted to Mr. Fry for the opportunity of describing 

 this very interesting species.

This species is very near to P. senegalensis, but is broader 

 and less convex ; the head has the sides more parallel, the 

 tubercle behind the eyes being more prominent ; the surface 

 behind the eye is more distinctly punctured. The epistome
