Mr. Bloomfield exhibited two specimens of Hesperia lineola, 

 Ochs., found by him in his series oi H. thaumas, Hufn., taken 

 in Essex. 



Mr. T. R. Billups exhibited Meopus trispinosus, Wat., a very 

 curious three-spined weevil from New Zealand, Poropleiira 

 monstrosa, Olivr., from Brazil, belonging to the family 

 CryptocephalidcB ; also specimens of the Colorado Potato 

 Beetle {Doryphora decem-lineata, Say.), and said that this 

 destructive creature became a perfect beetle within a month 

 from the hatching of the eggs, which were of a yellow 

 colour ; the larvae were pale yellow with a reddish tinge, and 

 a lateral row of black dots. Messrs. Walsh and Riley, the 

 editors of the American Entomologist, had stated that there 

 were three broods of the species every year in North Illinois 

 and Central Missouri, each of which went underground to 

 pass into the pupa state ; the first two broods came out of the 

 ground in the perfect state about ten or twelve days after- 

 wards ; the third brood staying under ground all the winter, 

 and emerging late in the following spring, just in time to lay 

 eggs upon the young potato leaves, which were devoured 

 to such an extent as to almost destroy the entire crop in some 

 localities. It had various and numerous enemies, which preyed 

 upon it in the larval stage, such as beetles, Hemiptera, and 

 also certain species of Diptera. A dry hot summer was most 

 injurious to the pupas, as they died in consequence of the 

 want of moisture in the soil ; but the most efficacious remedy 

 against this pest was found to be hand-picking. Another 

 closely allied species, Doiyphora jmicta, Gesmar,, an inhabitant 

 of the Western and Southern States, was not so destructive, 

 as it fed on the wild potato, not eating the cultivated species. 

 Mr. Billups also exhibited a species of Conocephalus, of the 

 family of Locustariae, Latreille, from tropical Australia. 



Mr. Watson exhibited a nest of a species of Mantis (made 

 among the roots of various plants), also two living examples 

 of the Mantis, and remarked that the nest had been sent to 

 him from Sydney, where the species was said to occur freely. 

 Besides the two specimens now alive, many others had 

 emerged during transit ; the box arrived in London about a 

 fortnight previous to the meeting, and the two specimens 

 shown had emerged three days before. Mr. Billups stated 

 that the species was Mantis religiosa, Latr. 



Mr. Skinner exhibited an example of a locust Acridiiiin 

 migratoriuin, Fab., taken by himself in the Wandsworth Road 

 on the 1 8th instant 



Mr. C. H. Collings exhibited a Hymenopteron parasitic on a
