Genital pieces: Male. — Last ventral se5::ment broadly excavated on the 

 posterit)r margin. \'alve short, occupying the concavity of the hind mar- 

 gin of the last ventral segment; its posterior edge but feebly convex, with 

 a minute central tooth. Plates flat, rather long-triangular, their edges almost 

 straight, above abruptly narrowed to long, slender, flaccid tips, clothed at 

 their apex with soft white hairs. Pygofers much longer than the plates, 

 thickly beset with long, stout, brown bristles. 



Female. — Penultimate ventral segment narrowed at the middle, the ulti- 

 mate long, rounded toward the apex, which is truncated and compressed 

 against the sides of the pygofers; surface finely punctured. Pygofers long 

 and narrow, clothed with stiff bristles. 



Described from six individuals representing both sexes (No. 

 605 male. No. 623 female). This neat little species is very closely 

 allied to 6". consors Uhl. , but appears to be sufficiently distinct. It is 

 quite variable in the shade of the ground color, and in the depth 

 and extent of the dark markings, especially on the abdomen. 



The genus Scaphoideiis has been recently characterized by Mr. 

 Uhler in the ' ' Trans, of the Maryland Academy of Sciences for 

 1888, p. 33 (1889)," and by M. Provancher in his "Petit Faune 

 Ent. du Canad. Vol. 3, p. 276." It agrees with Thamnotettix ^iwd 

 Phlepsius in wapting the second short transverse nervure connecting 

 the inner branch of the first sector with the second sector, and by 

 this same character may be separated from Platymetophis, with 

 which it seems to be nearly parallel. Its true position will doubtless 

 be found between the two former genera which it ser\^es in a measure 

 to connect. It is distinguished from all other genera of the JassidcB 

 known to me by its elongated antennal setae.

Regarding Stenopodius flavidus. 



The remarks of Prof Smith on this insect in Vol. V of Ent. 

 Amer. p. 122, have reminded me of an observation I made while 

 in Arizona which tends to disprove the correctness of Dr. Horn's 

 surmise that the species is subaquatic in its habits. I captured two 

 specimens of this remarkable insect on a low plant (one of the Mal- 

 vacecE I believe) at least three miles from any water. Their presence 

 in such a situation leads to the belief that they can hardly be sub- 

 aquatic, as it is doubtful if two specimens would travel so far from 

 water over such an exceedingly dry country and come to rest on the 

 same plant. These two specimens were all I ever saw. Taken at 

 Winslow, Ariz., in early July. H. F. Wickham.
