96 NATURAL HISTORY 



more hairs on their posterior thoracic scales. The thoracic scale in the 

 female is mottled or tortoise-shell. The penis is horny and terminates 

 in two hooks, which I imagine lays hold of some part of the vagina. 

 Towards the last of the season I found a vast number of males whose 

 penises were separated and the root projecting. 



The female parts are two ovi- clusters ; each consisting of six ducts, 

 having in each only about six eggs which are oblong ; each of these six 

 terminating in one duct, making two ducts for the two clusters, which 

 again terminate in one. This common duct to the whole communi- 

 cates with the receptaculum seminis ; or they both open externally by 

 one common opening ; so that there is no duct passing from the one 

 into the other, as in the moth, &c. 



The receptaculum is pretty large. There are not the glands for the 

 sticking mucus, as I suppose that is not wanted, the eggs being laid in 

 moist places, &c. ; but [in the female] there is the second or single bag, 

 filled with a white mucus, whose duct enters the common duct of all 

 the ovarian tubes, as in the moth. This part must have a fixed use, as 

 it is found in all 1 . The opening of the anus is distinct, nearer to the 

 back of the animal. They copulate somewhat similar to the qua- 

 draped, or perhaps rather like a bird ; the male gets on the back of the 

 female. They are about fifteen minutes in the act ; sometimes more, 

 and sometimes less. 



On the Rose-beetle [Cetonia aurata~\. — This is a flat green beetle with 

 some small irregular specks of yellow, found commonly on the flower of 

 the Spirea, also sometimes in the male parts of the rose, and which I 

 believe feeds on the pollen. It is seen in the months of June, July, 

 and till the middle of August ; it is seldom seen to fly, but it flies if 

 much disturbed. When confined on the ground under a shade, it buries 

 itself and comes up again. The male is I believe the larger of the 

 sexes. The female is of a brighter green, having few or no yellow 

 specks. 



Of the Grasshopper \_Phasgoneura viridissima] . 



A large green grasshopper with small eyes and a long projecting 

 tail, was caught in the latter end of August 1789 ; it was a female. 

 Her belly was full of eggs, which were black, and pretty long ; but when 

 they were small they were of a lighter colour. She had a long oviduct 

 like an intestine that passed between the two ovaria. Just before the 

 ter m ination of the oviduct, or near its opening externally, was a round 

 bag full of mucus [spermatheca], whose duct entered the oviduct.

 they pass outwards.]
