56 PAPERS BY DR. B. CLEMENS. 



second article dark brown exteriorly. Head and front 

 yellowish-brown. Thorax dark brown, varied with yellowish. 

 Fore-wings fuscous, varied with yellow, which prevails along 

 the inner margin, with fuscous spots around the apical 

 margin, and in the ? a large discal fuscous patch. The 

 fore- wings, of the $ have more of the yellowish hue than the 

 ? ; cilia yellowish. Hind-wings pale brownish-yellow, cilia 

 the same. Exp. al. 8 to 11 lines. 



The following species likewise form a new genus ; at least, 

 I am not aware that any has been formed into which they 

 can be received. Plumifrontella is found here in June and 

 July, when it may be taken at light. I am unacquainted 

 with the embryonic history of the species described, and have 

 never met with the female Plumifrontella. The genus, 

 I think, belongs to the group Exapatida, and as the females 

 in some of the genus are apterous, that of Plumifrontella 

 may be unsupplied with wings. The antennaa should be 

 examined very carefully, otherwise their peculiar structure 

 will be overlooked and mistaken for simple filiform organs. 



ANAPHORA. 



Head hairy, concealed by the labial palpi in the <? , free in 

 the ? . Ocelli none. Eyes small. Antennse but little 

 longer than the thorax, serrated beneath, with the ends of the 

 articles finely ciliated. Maxillary palpi moderately long, 

 scaly and three-jointed in both $ and ? . Labial palpi in 

 the $ * greatly developed, ascending and thrown back on the 

 dorsum of the thorax, which they equal in length ; the first 

 article scaly, arctate and equal, to the superior margin of the 

 eyes, and the two succeeding ones equal and furnished with 

 abundant spreading hairs; in the ? short, not ascending 

 above the eyes, articles nearly equal, the first and second 

 hairy beneath, the third rather smooth and porrected.
