298 ENTOMOLOGICAL NEWS. [ July, '14 



A single male specimen captured by Mr. Akio Nohira at 

 Yoshino, Province Yamato, is in my collection. There are 

 also a few specimens obtained along with that just mentioned 

 in Mr. Nohira's collection. 



This species is quite distinct from all other known species 

 in the number and arrangement of tubercules of prothorax, 

 and of course in many other respects. 



Since there has been hitherto a single species of Dilaridae 

 recorded from Japan by McLachlan, the discovery of the pres- 

 ent species adds one more to our fauna. The Japanese species 

 of the family, therefore, are as follows: 



1. Dilar nohirae n. sp (Yoshino, Yamato) 



2. Re.ravius japonlcus (McLachlan) ("Tukushima") 



Dilar japonicus McL., Ent. Month. Mag., xix, p. 220 (1883) ; Rexa- 



vius japonicus Navas, Mem. de la Real. Acad. de Cienc. y Art. de Bar- 

 celona, vii, pp. 665-666 (1909). 



A New Sugar Cane Aphis (Hemip., Homop.). 



By H. F. WILSON, Entomologist, Oregon Agricultural Col- 

 lege, Corvallis, Oregon. 



(Plate XIII.) 

 Aphis bituberculata n. sp. 



Specimens of this aphis collected on Saccharum officinarum 

 at Audubon Park. New Orleans, Louisiana, were sent to me 

 several times during the season of 1912. I have compared 

 these specimens with descriptions, etc., of the other aphids 

 found on sugar cane without being able to refer this species to 

 any of them. I am therefore describing it as new. 



Alate viviparous female, General color dark green, antennae, legs 

 and nectaries dusky to black. Antennal tubercles present but not 

 elongate; antennae about two-thirds the length of the body, not quite 

 reaching to the base of the nectaries, and with six segments. 



The two basal segments are normal, while the third appears thicker 

 and longer than the fourth, or the fifth and sixth together, not 

 including the spur of the sixth ; the fourth is slightly longer than the 

 fifth, and the spur of the sixth is nearly as long as the third, fourth 

 and fifth together. The third segment bears six to ten irregular-sized 

 sensoria, all situated on the inner side, the fourth sometimes with a
