Mr. C J. Gall an on new Longicorn Coleoptera. 377 



I desire to set up this conception in opposition to the theory 

 of gastrulation which at present prevails. I would mention 

 once more that I reserve for my subsequent paper the full 

 description of my investigations and the detailed statement of 

 proof, as well as the consideration of the literature of the 

 subject. In the present communication I wished to substan- 

 tiate my view as shortly as possible.

LXT. — Descriptions of some new Loncjicorn Coleoptera from 

 the Indian Region. By C. J. Gaiian, M.A., of the British 

 Museum (Nat. Hist.). 



[Plate XIX. figs. 4-7.] 



The new species described in this paper form part of some 

 recent accessions to the British-Museum collection. Those 

 from the collections made by Mr. G. Q. Corbett in Burma 

 and by Mr. A. Bell in South India were presented through 

 the intermediation of Dr. Andrewes ; while most of the re- 

 maining species described are from the collections made by the 

 late Mr. E. T. Atkinson.

The underside of the head is crossed by a deep intergenal 

 groove, which is followed by a second shallower and some- 

 what ill-detined groove ; both grooves are slightly bowed 

 forwards in the middle. The prothorax is somewhat con- 

 stricted anteriorly ; it is obtusely angulate and provided with 

 a very small tubercle at the middle of each side ; it is wrinkled 

 above over almost the whole surface, the rugai having a wavy 

 course in a general transverse direction ; two longitudinal 

 impressions, bending towards the middle line to unite ante- 

 riorly, cut off a central space which is wrinkled like the rest
