284 LMay, 1805. 



The President exhibited a species of Bolhocerus, sent liy Mr. Odowahn, trom 

 Gawlior, in Australia. Mr. Odewahu mentioned that he had found this species in 

 the ground of the hard road, and that it made a noise (as he thought) by rubbing 

 the tarsi and coxaa together. The President said that he had found the European 

 species, B. galUcus, in hard limestone rock, into which it burrowed for a considerable 

 distance. Professor Wcstwood thought that Mr. Odewahn must have been mistaken 

 as to the manner in which it caused the sound. 



Mr. Moore exhibited a bos of diurnal Lepidoptera, captured by Capt. Lang in 

 the North-Western Himalayas ; among them was a new species of Lyccenidce, an 

 Anthocaris, closely allied to A. cardamines, and the European Pieris Dcvplidice. 

 Mr. Moore also exhibited two species of Heterocerous Lepidoptera, attacked by 

 Sphwroid growths ; these were found by Mr. A. E. Eussell at Darjeeling. 



Mr. Janson exhibited a large collection of insects of all orders, captured by 

 Mr. Eussell in the Himalayas, principally in the neighbourhood of Darjeeling; 

 among them were many beautiful new species of Geometridce. 



Mr. Saunders exhibited seven different kinds of galls, collected by IM^r. Lowne 

 in Syria ; some of these were very peculiar, and he had not been able to satisfy 

 himself that all of them were really the production of insects. They were on 

 species of Acacia; Atriplex, Tamarix, jErua, Rcemurea, and a kind of gi'ass. 



The President mentioned, that last summer when crossing Monte Moro, he 

 found numerous little circular holes in the snow, at the bottom of which there 

 was invariably some species of insect in a dead or torpid condition, and occasionally 

 a piece of peat. He concluded that the insects had flown or fallen on the snow, and 

 had formed these depressions by the radiation of heat from their bodies. 



Professor Wcstwood made some observations on the " Chigoe " or " Jigger," 

 with special reference to a memoir just published by Dr. Carsten, of Moscow. He 

 added, that although this paper was most elaborate in its anatomical details, it 

 added no information on the most important point, viz., the larval state of the 

 insect, and that on this subject we were as much in the dark as ever. The 

 Professor commented very strongly on the generic name employed by Dr. Carsten, 

 viz., Bhyncoprion of Oken, which is in reality only a synonym of a genus of Acari, and 

 had no connection with the insect in question, more than the fact that the "Jigger" 

 was once considered an Acarus. This was less excusable, because he had himself 

 formed the genus Sarcopsylla for the reception of the species, in the transactions 

 of this Society in 1840 ; and Guerin-Meneville had also employed the term 

 Dermatophilus for the same insect. 



Mr. Bates said that he had frequently suffered from the attacks of the "Jigger," 

 but could say nothing about the larval state. The popular opinion was that 

 the abdomen of the female burst in the flesh, and that the larva) fed in the wound ; 

 he could not, however, confirm this. 



Mr. Bates read a memoir on the species belonging to the Gcodephagous genus 

 Agra, found in the Amazon region, comprising 47 species, of which he had himself 

 taken 42, 31 of them being new. Mr. Bates remarked that these insects possessed 

 crepitating powers, the explosion not being audible, but capable of being distinctly 

 felt, and leaving a stain upon the fingers.
