three feet high, destroyed by them in one Summer, as well as the stakes 

 which supported them. Red currants are also liable to their attacks, be- 

 sides various other shrubs and plants, while the root of grasses also serve 

 them as food. — L. H. Joutel in Jour, of the N. Y. Ent. Soc, June, 1893. 



Classification of the Tracheate Arthropods. — Pocock proposes 

 the following classification of this group (Zool. Anz., July 3, 1893): 



A. Generative organs open in the anterior part of the body, apparently 



on the third metacephalic somite Progoneata. 



a. Antennas branched ; segments of body of adult not formed by fusion 



of two embryonic somites .... Class Pauropod Lubbock. 



b. Antennae aimple ; some segments of body of adult formed by fusion 



of two embyonic somites .... Class Diplopoda Blainville. 



B. Generative organs open at the posterior end of the body close to the 



anus Opisthogoneata. 



a. Metacephalic region of the body not divisible into distinct regions, 



but composed of a series of similar or approximately similar 

 somites, each of which bears a pair of ambulatory appendages 



Homopoda. 

 a. Two ( perhaps three ) pairs of gnathites, feet biunguiculate 



Class Symphyla Ryder. 

 B. Four pairs of gnathites ; feet tipped with one claw Class Chilopoda. 



b. Metacephalic region of body divisible into two distinct regions, the 



anterior of which, composed of three somites, bears three pairs of 

 legs, while the posterior is never in the adult furnished with ambu- 

 latory appendages Class Hezopoda.
