with a dark cloud or two near the middle. Posterior wino;s 

 pliimbeo-fuscous. Thorax nearly white, with the anterior 

 margin narrowly black. Head black, antennae pale and pecti- 

 nated. Abdomen stout, slightly tufted, plumbeous, paler at the 

 base. The antennse might lead us to suppose it a 3" , but the 

 abdomen disproves this. I cannot doubt that it is the 9 of my 

 104. [Further notes upon the same insect, extracted from 

 Doubleday's mss. are given below.^] 



1 Genus. ? 



Antennoe as long as the thorax, bipectinate their whole length. 



Palpi two, distinct, triarticulate, second joint longer than the first, both rather stout, 

 scaly, setose at the base ; terminal joints small, acute, scaly. 



Maxillce none. 



Eyes large. 



Wings entire, superior ones rounded at the apex, rather long. 



Posterior tibiffl clothed with long hair. 



Sp. 1. Alts clnereis, sfrigis numerosis abhrevlatis nigris, aniicls strigA transversa juxta 

 basin alterdque lunitd ad apicem distinctioribus nigris. Habitat St. John's Bluff, E. F. 



Wings cinereous, all with numerous, abbreviated, black strigse. Anterior with a 

 broader, transverse striga near the base, a black luniile at the apex, commencing on the 

 costal margin near the apex, and terminating on the posterior margin at about an equal 

 distance from the apex, and two more distinct, abbreviated, black strigse near the anal 

 angle. Thorax cinereous, varied with black. Abdomen cinereous. 



Differs from Cossus in the bipectinate antennJB. In form, texture of the wings, and 

 coloring, it is closely allied to that genus. Probably it is an internal feeder. The neu- 

 ration also of the anterior wings is different, 



[Dr. Harris adds to this the following note: — $ , Antennos doubly pectinated to the 

 tip. Wings gray, semi-diaphanous, fuscous at base ; first pair rounded at tip, with a 

 narrow, transverse, black band near the base, and a semi-circular one at the tip; both 

 pairs with dusky, reticulated lines.] 



The Hepialldm seem to have but few characters in common. The larvse, it is true, 

 are allied in habit and form, especiallj' those of Zeuzera and Cossus. 



In Zeuzera, Cossus, No. 104 and Heplalus (all the genera that come under this group), 

 the absence of the tongue is all that in the perfect state binds them together, 



Zeuzera has semi-diaphanous wings, both nearly similar in neuration. The $ have 

 rather short antennse, with long pectinations about one half their length. In the ? 

 they are simple bvit woolly at the base. They have no tongue, and apparently no palpi. 

 The larva is a-n internal feeder. 



Cossus has the wings more thickly clothed with scales, especially below; the neura- 

 tion is veiy different and rather complicated. The antennae are pectinate, or rather 

 have on the inner side of each joint a broad, flat, or lamelliform process. The palpi, 

 two in number, are distinct, triarticulate, rather stout. Tongue wanting. 



My 104 is a Cossus, with bipectinate antennae, and some difference in the neuration of
