a few remarks on the well known Cockroach, or Black-beetle 

 as it is erroneously called, of our kitchens and houses, and 

 must refer to DeGeer, Kirby and Spence, and other writers, 

 who may be consulted with profit and amusement. 



The female lays an oval bag containing J 6 eggs ; and after 

 having carried it about at the extremity of her body, by means 

 of her forceps, until she has found a convenient place, she de- 

 posits it: out of this horny bag the young Cockroaches issue, 

 and rapidly increase in size until they arrive at the perfect 

 state (having passed through that of the pupa), when the males 

 become winged, but the females remain apterous. They are 

 most active animals; and being nocturnal, very voracious, and 

 omnivorous, they are very destructive in houses where they 

 abound. Traps are employed for catching them, and common 

 wafers that are coloured with red-lead strewed about before 

 going to bed are said to be very effectual in destroying them, 

 and probably sprinkling spirits of turpentine in their haunts 

 would drive them away. It is said that some species of Sphex 

 destroy them, and the Evania, a genus illustrated in our 257th 

 plate, is one of its parasites. In Russia and Finland B. Orien- 

 talis is a perfect pest, and although it seems to be naturalized 

 everywhere, no one can determine whether it was originally a 

 native of Asia or of South America, one of the many proofs of 

 the necessity of speedily recording the geographical distri- 

 bution of insects, which is intimately connected with the con- 

 stants of nature proposed by Mr. Babbage. 



There are 1 1 species registered as inhabitants of England ; 

 amongst them :
