case in question were not to be explained by mechanical irritation alone due to the 

 presence of hairs in the tissues. The subject was a new one to him, and he had 

 looked up all the medical literature bearing on it. Lord Walsingham, Mr. Tutt, 

 Prof. Poulton, Canon Fowler, and Mr. Jacoby made some remarks on the subject, 

 (c/. Ent. Mo. Mag., 1895, pp. 179-180, Eds.). Dr. P. A. Dixeyread a papei-, entitled, 

 " On the Relation of Mimetic Patterns to the Original Form." The paper was 

 illustrated by a number of coloured diagrams. Prof. Poulton expressed his 

 gratification with the paper, and that the Hope Collection under his charge had 

 afforded material for the work. He thought the result of the paper was to give 

 support to the theories of Fritz Miiller rather than to those of Bates. Mr. 

 Blandford, Mr. Tutt, and Prof. Meldola continued the discussion. Dr Sharp 

 contributed a paper, entitled, " The Rhynchophorous Cohoptera of Japan. Part 

 IV." — H. Goss and W. W. Fowieb, Hon. Secretaries.

This Section, like the 1st, may be ranked as a Sub-genus. It 

 comprises two series of species characterized by differences in the 

 arrangement of the endings of the bristling hair on the pobrachial 

 and postical nervures. The nervures upon which such hair is found 

 are the same as in Ulomi/ia, and the former Section. Analogous 

 differences in the bristling hair of the radius and cubitus taken into 

 consideration (tacitly or expressly) with features of the ^ antennje 

 and superior (^ genital appendages, serve for subdivision of the series. 

 The antennae are 16-jointed in both sexes of all the species. 



Classification of Species of the 2nd Section of Pekicoma. 



A. Wing broadly ovate ; apex rounded between the cubitus and the prsbrachial 



nervure ; the endings of the bristling hair on the pobrachial branches 



and postical nervure in a re-entering angulate line with one another; 



the ending of the same hair on the anterior radius less or not farther 



advanced than its ending on the cubitus. 



a. Bristling hair extending farthest upon the anterior radius and cubitus, and 



not quite so far on the posterior radius. Third joint in the S antenna 



longer and narrower than the 2nd, and provided above on the outer side
