THE CANADIAN ENTOMOLOGIST. 



Last two abdominal segments with a broad median dusk mark on the 

 dorsum. Whole body clothed with short, fine, black hairs. 



Oviposition has not been observed, but probably takes place during 

 June and July, but in the case of Z. mendax it may be deferred till Sep- 

 tember, as Renter records adult specimens captured during that month. 



I have reared the nymphs of both species from apple branches sent in 

 from Brockport, Syracuse, Albany, Waterloo, East Palmyra, Lafayette, and 

 Batavia, N. Y. In some apple orchards they are serious pests, deforming 

 with their feeding punctures a large proportion of the fruit of certain 

 varieties. 



^ NEW SPECIES OF PHALANGIDA FROM MISSOURL 



BY CYRUS R. CROSBY, ITHACA, N. Y. 



Nemastoma dasycnevmm, n. sp. — Length, .95 mm.; width of abdomen, 

 .59 mm. General colour in alcohol very dark brown, in life nearly black; 

 in one s])ecimen the body is distended, making it appear white, with black 

 markings, but in the other, which was studied alive, tliis is not the case. 



Cephalothorax squarely truncate in front, with the lateral angles 

 oblTque when viewed from above. Eyes small, situated on a low tubercle 

 close to the anterior margin, separated by a liltle less than their diameter, 



each one surrounded by a series of sharp 

 black spines. Frontal pieces of the cephalo- 

 thorax two in number, transverse, contiguous 

 and gradually enlarged laterally. Two-thirds 

 the distance from the eyes to the posterior 

 margin of the cephalothorax there is a distinct 

 transverse groove, which becomes indistinct 

 at the sides. In the distended specimen the 

 thickened parts of the tegument are separated 

 from each other and contrast sharply with the 

 snow-white connecting membrane. The first 

 five dorsal abdominal segments are united 

 into a single piece, free from the cephalo- 

 thorax, and with the anterior and i)Osterior margins convex. The sixth, 

 seventh and eighth dorsal segments are represented by narrow, transverse 

 sclerites. On the ventral side five segments are distinguishable. The first 

 is large, narrowed in front and separated from the terminal portion by a 



January, 1911
