a piece of the hedgehog's flesh. Latreille says that they are 

 either bhnd, or that their eyes are not apparent. I examined 

 them minutely with a microscope, but was unable to discover 

 their eyes : they must however possess these organs, or some 

 delicate sense to compensate for their absence, since one of 

 them, that I placed near a lamp, constantly turned away to 

 avoid the light. They belong to the RicimcB, Latreille's fifth 

 family of Trachean Arachnidcc ; their spiracles are two in 

 number, one is placed on each side of the abdomen ; they have 

 eight six-jointed legs ; the tarsi are didactyle ; the thorax and 

 abdomen are united, and are composed of only a single seg- 

 ment ; the abdomen is by far the largest part of the body; in 

 the front of it is an oval coriaceous plate,— the scutum ; the 

 palpi are two in number, large and oval, and are single-jointed; 

 they must, I should imagine, live entirely by suction, in which 

 they are probably assisted by the palpi ; the rostrum is well 

 adapted for maintaining a firm hold, as it is deeply serrated, the 

 serrge pointing backwards. In this species, the head, legs, 

 palpi, and the scutum are brown, and the abdomen a livid white. 

 Some of this genus lay a large number of eggs, which, ac- 

 cording to M. Chabrier, pass through the rostrum. But here 

 a question presents itself as to how they are originally placed 

 on the animal. Are they attached to it from its birth; or how 

 and when are they placed there, as their locomotive powers are 

 so limited? Yours, &c. W. Longman. 



13. Insects captured at Shellness and Neighbourhood. — 

 Near the end of last month I took at Pegwell Bay, Shellness, 

 and in the surrounding neighbourhood, the following insects : 



Notoxus monoceros Platyderus ruficollis Megachile centuncularis 



Allecula sulphurea Synuchus vivalis Willoughbiella 



Cicindela maritima Odontomyia viridula Allantus 



Broscus cephalotes furcata Tenthredo 



Calathus piceus Tabanus bovinus Cephus 



rufangulus Eristalis sepulchralis Nematus, and several 

 mollis intricarius species of each. 



Gymnosoma rotundata 



Broscus cephalotes. — The habit of these insects is very 

 curious ; they are found only in the sand on the sea-shore, 

 and live in dens about three inches deep and half an inch wide, 

 which are made in a diagonal position in the sand, where it 

 is mixed with decomposed stalks of Elymus arenarius. They 

 appear to rove during the day occasionally, but, upon any
