GENERA AND SPECIES. 189 



with a curved one near the posterior angle : inferior wings 

 rather small, with 4 furcate, and several other nervures, cilia 

 short : intermediate and posterior tibiae spurred at the apex, 

 with a pair of spurs also below the middle. 



4. Flavipes. Curt. 



Rather silky ochreous : thorax and abdomen piceous, inferior wings, 



and under side, also the coxas and thighs, fuscous. (Length 3, 



breadth 11 lines.) 



The Phryganea atrata of Fabricius, which I did not possess 

 at the time the Guide was pubhshed, does not belong to this 

 genus, but his P. palhpes, I think, may be considered the 

 type of it.

Gen. 846. — Rhizolitha. Curt. 



Palpi hairy, not projecting beyond the head, porrected horizontally : 

 antenna? rather long and stout, slightly ciliated beneath : head 

 with a conical brush of hair projecting over the face : thorax 

 crested : abdomen subdepressed, truncated, and tufted at the 

 apex : wings incumbent when at rest, superior, long, and narrow, 

 with a bifid line at the base, posterior margin rounded, and 

 slightly dentated : inferior wings, with the margin undulated. 

 I am totally averse to changing names, especially generic : 

 I therefore think the practice a very bad one, of raising a 

 specific name to designate a genus, by which both are dis- 

 turbed, except as in the present case, where the name is 

 merely a synonym, the type being the Noctua Lambda of 

 Haworth's Lep. Brit. 



Gen. 867. — Lampetia. Curt. 



Palpi densely clothed with short scales, forming a beak : maxillae 

 shorter than the antennae, which are long: thorax with a sub- 

 conic crest on the back : abdomen very flat on the back in the 

 males, and rounded at the apex : wings decumbent when at rest ; 

 superior rounded at the shoulder, truncated at the apex, which 

 is acute : inferior slightly scalloped : thighs and tibite broad and 

 compressed. 

 I do not know a better characterized form amongst this 



difficult family, than the Noctua croceago of Fab. the type of
