and posterior sides of the fifth longitudinal vein there are some 

 small brownish-black alternating spots ; the remainder of the wing 

 is unspotted; the posterior transverse vein straight and rather 

 perpendicular. 



Observation. — Although this species is very similar to the fore- 

 going, and I have only a single individual before me, its specific 

 distinctness seems to be beyond doubt. The straight and rather 

 steep posterior transverse vein, the lateral frontal stripes reaching 

 farther forwards and the middle frontal stripe not being dilated 

 anteriorly afford the best characters for distinguishing let. valida 

 from let. clara.

Syn. Tetanocera pictipes Loew, Wien. Ent. Monatsch. Ill, 292. 



Front almost more pale brownish than yellow, opaque, beset, on 

 its anterior part, with sparse short black hair, rising from hardly 

 visible dark dots; hardly a trace of an excavated middle stripe; 

 all that gloss which other species possess is totally wanting, and 

 only a fine whitish dusted longitudinal line is visible. Each side 

 of the front near the border of the eye a brownish-black dot, and 

 more forwards between the antennae and the anterior corner of the 

 eye another small brown or blackish-brown spot. The face is 

 silvery white, and recedes only moderately; its middle is marked 

 with a very small black spot ; on the cheeks there is a brown or 

 blackish-brown longitudinal streak. The first and second joints of 

 the antennae are yellowish-brown ; the third is more yellowish-fer- 

 ruginous, scarcely longer than the second, not much pointed, its 

 upper side being distinctly excised; the black bristle has a brown- 

 ish-yellow base, and a scanty, rather long black pubescence ; some 

 individuals differ by the color of the antenna; being quite ferrugi- 

 nous brown. The upperside of the thorax is quite opaque, brown- 

 ish cinereous, closely covered with small dark brown dots, which 

 coalesce to larger spots, forming four rows, and having a rather 

 variable size. Scutellum gray, in the middle brown, with small 

 dark brown dots, on the borders with four black dots bearing 

 the ordinary bristles, the hindmost of which are far longer than
