A HISTORY OF DEVONSHIRE 



EcToBiDAE {continued) 



the large cockroach (Blatta orientalis) gene- 

 rally contains sixteen eggs. The latter does 

 not begin to reproduce her species until the 

 fourth year. When germanica begins to re- 

 produce is not known, but is presumed to do 

 so at the same age 



Blatta orientalis, Linn. Common cockroach, too 

 well known as a household pest 



Periplaneta americana, Linn. About twelve years 

 since Mr. G. C. Bignell observed a great 

 number of these cockroaches in the streets of 

 Plymouth, evidently flown from a ship then 



EcTOBiDAE (continued) 



in the Great Western Dock. Since that 

 time they have established themselves in 

 several bakehouses in Plymouth, Periplaneta 

 americana has driven out Orientalis from 

 more than one bakehouse in Plymouth; the two 

 do not appear to be able to live in harmony 



Panchloridae 



Rhyparobia madeirae, Fabr. Several specimens 

 observed by the same gentleman in the 

 streets of Plymouth, about twenty years since, 

 having flown from a ship in the Great 

 Western Railway Docks

Gryllotalpidae 



Gryllotalpa gryllotalpa, Linn. Mole cricket, 

 occurs rather frequently in the neighbour- 

 hood of Exeter. A few years since several 

 were found in the streets early in the morn- 

 ing (Parfitt). Mr. Bignell has seen three 

 found in a potato patch, each had consumed 

 a great portion of the potato under which 

 they were found in September 



NEUROPTERA 



Stone-flies^ May-flies, Dragon-flies, Caddis-flies, etc. 



Owing to the very varied nature of the country and to the fact that the southern portion has 

 been carefully worked by such keen observers as Mr. Parfitt of Exeter, the Revd. A. E. Eaton, 

 Mr. G. C. Bignell of Plymouth, and, in earlier days, by Dr, Leach, while the northern portion has 

 received attention from Mr. MacLachlan, Mr. Stanley Edwards, and myself, the Devonshire list of 

 Neuroptera is, even now, a fairly lengthy one.
