Exhibitions, &c. 
Mr. S. Stevens exhibited four large cases of Lepidoptera and Coleoptera from the 
Himalayas, containing numerous rare species, and many of the Lepidoptera having 
been bred from the larva. 
Mr. Bates gave an account of Mr. Bartlett’s explorations in the Amazons country ; 
he had gone up the Amazons River as far as Nauta, and had thence followed the 
course of the Ucayli until he reached the eastern slopes of the Cordilleras: a collection 
of objects of Natural History, including several thousand insects, the result of four 
months’ labour, had been despatched, and might shortly be expected in England. 
Whilst speaking of the Amazuns, Mr. Bates desired to mention that the local 
authorities at Para, which was merely the chief town of a province of Brazil, had 
recently voted £600 towards the expenses of scientific researches undertaken by 
Agassiz. 
Prof. Westwood read extracts from a letter from M. Snellen van Vollenhoven, 
recounting some of his entomological experiences during the past season. 
A conversation ensued respecting the female Lepidoptera which occur in autumn 
with undeveloped ovaries. Mr. J. Jenner Weir inquired whether such females, after 
hybernation, were found to have developed ovaries in the spring? It might be that 
early hybernation was an aid to the development of the ovaries. Prof. Westwood 
thought it probable that the ovaries were developed during the winter; the difficulty 
was to say when the impregnation took place; this, in the case of wasps, must bé in 
the autumn, since the males did not survive the winter. Mr. M‘Lachlan observed 
that nearly all the hybernated specimens of Vanessa were females: but he had himself 
taken Cerastis Vaccinii and C. spadicea respectively in copuld on sallow-blossoms in 
the spring. 
The following are descriptions of the three new exotic Longicorn beetles exhibited 
by Prof. Westwood at the previous Meeting :—

C. piceo-niger ; mandibulis subfalcatis, intus ante medium dente conico parvo 
armatis, apicibus oblique truncato-emarginatis; autennis subcrassis, capitis 
(cum mandibulis) et pronoti longitudine; capitis disco ruguloso, postice levi, 
punctato; pronoti marginibus lateralibus subserratis, lateribus rude punctatis, 
disco sublevi nitido, tenuissime punctato, angulis posticis oblique emarginatis; 
elytris subrugulosis, punctatis, et singulis costis 5 parim elevatis sed sat 
distinctis notatis; tibiis anticis extus 4- vel 5-denticulatis, denteque forti 
subapicali armatis, 4 posticis intus dense fulvo hirsutis. 
Long. corp. lin. 153; mandib. lin. 24. 
C. Spondyloide tertia parte major, magis nitidus et depressus, denticulis tibiarum 
anticarum minoribus.

Sub-genus novum CantHaroptatys, Westw. 
A genere Cantharocnemide differt corpore magis depresso, mandibulis multo cras- 
sioribus et dente subbasali armatis, antennis abbreviatis, elytris cicatricosis 
(nec punctatis), juguli angulis lateralibus valde prominentibus.
