half their length ; the latter broad and short, almost cylindrical, meeting 

 on the ventral aspect nearly to their tips, thus forming a small opening 

 around the anal style, a little separated basally beneath the ultimate ventral 

 segment ; plates slender, weak and flaccid, but slightly exceeding the 

 pygofers in length, fringed with long soft hairs. Female : Last ventral 

 segment as in the male, except that the apex is truncated or slightly con- 

 cave ; pygofers short and thick, the blunt apex but little exceeded by the 

 ovipositor,

 ton, Ont., James Johnston, Esq. Described from five male and six 

 female examples. 



Allied to /. lac/irjy ma/is, from which it can be readily separated by its 

 smaller size, different markings, and the form of the genitalia, 



L'Abbe Provancher, in his Petite Faune Ent. du Canada III., p. 288 

 (Jan. 1890), describes a very pretty little species oi Idiocerus as Bythos- 

 copus clitellarius Fitch, with the reference " Third Rept. Inj. Ins. p. 69"; 

 this should have read No. 69, and may be found on p. 365 of the Trans. 

 N. Y. State Agl. Soc. for 1856. Fitch, however, here refers to Jassus 

 clitellarius Say, a species of Thamnotettix and not to the insect described 

 by M, Provancher, for which I now propose the name Idiocerus Pro- 

 vancheri. This conspicuous little insect pertains to the group repre- 

 sented by /. niaculipennis Fitch. It is not uncommon here at Buffalo on 

 oak and other bushes through June, July and August. I have also taken 

 it at Muskoka, Ont., and have seen examples captured at Hamilton, Ont. 

 by Mr, James Johnston. 



Since the publication of my paper on Pediopsis in Ent. Am. for Sept., 

 1889, I have received from M. Provancher a pale example oi Bythoscopus 

 fenestratus Fitch., labelled Pediopsis flavesceiis Pro v., and accompanied by 

 a note stating it to be a typical example. It agrees well with his des- 

 cription in the Nat. Can., IV., p. 376, Dec, 1872, and it is the insect de- 

 scribed as Pediopsis flavescens on p. 295 of the Petite Faune Ent. du Can., 

 Feb., 1890. This, therefore, leaves the insect described by me as the 

 flavescens (Ent. Am., V., p. 173, No. 7) without a name. It is a well 

 characterized species, and may be called Pediopsis canadensis.
