Described from six specimens reared by Mr. Th. Pergande from 

 A cacia fa rnesiana . 



The larva, which is very dark, nearly black, with black head, was 

 found by Mr. E. A. Schwarz to web up and feed between the leaves 

 of the above tree in the streets of San Diego, Texas. 



The moth, while easily distinguished from the smaller lighter 

 golden type of the genus Ititeostrigella Cham., is still very close to it in 

 general appearance and in habit. 



The food plant oi P. hifeostrigella Cham, is Cassia chai/iiTcrisfa, on 

 which the larva, which is difficult to detect, spins together the leaf- 

 lets. I have reared this species repeatedly in the District of Columbia 

 in late July and early Aiigust. 



The only other described species of this genus from the American 

 continent is P. sexstrigella Cham. A much smaller species, diverging 

 considerably from the two others in coloration, but agreeing well gen- 

 erically. Lord Walsingham's three West Indian species are evidently 

 quite distinct from any of the continental forms. Judging from the 

 description and figure, acaciella Busck seems to resemble most Poly- 

 hymno cleoiioreUa\^2\%\x\.^z.vi\, described from Africa. 



Neither Chambers' nor Walsingham's delineation of the wing of 

 hitcosingella (Journ. Cin. Soc. Nat. Hist., Vol. II, i8So, Plate III, 

 Fig. 26, and Trans. Ent. Soc. Lond., 1S91, Plate VH, Fig. 78) is 

 very good, and gives no true idea of this elegant form. Chambers' 

 venation is wrong, even with his MS. correction, published by Mr. 

 Beutenmiiller, and Walsingham's figure does not show the caudate apex 

 sufficiently. Fig. i, Plate IX, is drawn from P. acaciella, but is 

 identical in venation and form with the wing of T'. luleostrigella Chzxa. 



cecophorid.f:. 



Triclonella, gen. nov. 



Antenna; four-fifths, slightly serrate and ciliate, basal rather long but simple with 

 pecten. Labial palpi long, smooth, recurved ; second joint somewhat thickened with 

 appressed scales, terminal joint long, but shorter than second. Maxillary palpi obso- 

 lete. Face, head and thora.K smooth. Fore wings elongate ovate, pointed ; 1 2 

 veins, 7 and 8 stalked, rest separate. Hind wings under I ; costa depressed from 

 middle to apex, anal angle rounded ; 8 veins, 6 and 7 parallel, 3 and 4 stalked, 5 

 out of the stalk of 3 and 4. Posterior tibia; hairy above. 



Type : T. pcrgaudeclla Busck.
