ART. 18 JASSID GENUS TYPHLOCYBA McATEE 15 



rowed from base, inner strongly curved outwardly near apex, then 

 downwardly, aciculate. Aedeagus slender, with two pairs of fur- 

 cate apendages at apex, of which the superior (anterior) are longer, 

 more curved, and more deeplj' forked (fig. 30). 



Female. — More whitish above than male, otherwise the same. 

 Eighth sternite somewhat emarginate laterallj^, and quite pointed 

 medially (fig. 104). 



Length, 3.5-4 mm. 



Tlolotype, — Male, allotype female and paratypes of both sexes, 

 Vancouver, B. C, C. F. Baker; two paratype males, Kaslo, B. C, 

 July 17, 1903, R. P. Currie, and a female, same locality, July 16, 

 A. N. Caudell, U. S. N. M.; paratype female. Royal Oak, B. C, 

 September 29, 1917, W. Downes (Downes). 



Holotype, allotype and paratype. — Cat. No. 28489, U.S.N.M. 



This species seems to be allied to T. hergmnni Tullgren,^^ but 

 probably is distinct. In that species the posterior (morphologically 

 inferior) appendages are the longer pair; in coloration T hergmani 

 differs by having two dark spots on scutellum. 



A specimen labelled only California (State Coll. Iowa) and some- 

 what damaged, is not made a paratype.

Typhlocyba lethierryi Edwards, .Tames, An additional species of British 

 Homoptera, Ent. Mo. Mag., vol. 17. p. 224, March, 18S1 [England]. 



Male. — Varies in color from stramineous as to head and thorax, 

 and whitish hj^aline as to tegmina, to sulphur or even orange yel- 

 low above, as far posteriorly as the crossveins, aj)ical cells in that 

 case hyaline though the tegminal margin and apical veins may 

 be colored. In highly colored specimens, according to Edwards, 

 the head, pronotum, and commissure may be more or less tinged 

 with reddish. Hypopygium : Lower posterior angle rather squari.sh, 

 somewhat incurved, upper with a slight emargination, above which 

 is a short inwardly projecting tubercle. The patch of bristles near 

 articulation of outer clasper is con.spicuous. Outer clasper with a 

 strong outwardly directed bristle near base as in T. glllettei (fig. 

 54), tapering more gradually than abruptly, the inner margin al- 

 most straight, the ajDex slightly spatulate; inner clasper with the 

 terminal fourth rather abruptly outwardly directed, as in T. com- 

 7nissuralis (fig. 27). Aedeagus with a slender, upcurved shaft, sur- 

 mounted at the apex by two pairs of curved and bifurcate ap- 

 pendages, the anterior pair on a short common stalk projecting an- 

 teriorly from the top of the central shaft (fig. 37). These figures 

 are from a specimen collected at Colesborne, England, by J. Ed- 



"Ent. Tidskr., vol. 37,, H'sft. 2, 1916, pp. C7-G9 [Norway].
