with a dark cloud or two near the middle. Posterior wino-g 

 plumbeo-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 antennae might lead us to suppose it a ^ , 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. ? 



Antennaj as long as the thorax, bipecthiate their whole length. 



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

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



Maxilla none. 

 Eyes large. 



"Wings entire, superior ones rounded at the apes, rather long. 

 Posterior tibice clothed with long hair.

Wings cinereous, all with numerous, abbreviated, black strig^e. Anterior with a 

 broader, transverse striga near the base, a black lunule at the apes, commencino- on the 

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

 distance from the apex, and two more distinct, abbreviated, black strig.^ near the anal 

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



Differs from Cossus in the bipectinate antennae. In form, texture of the win-s 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 :-$ . Antennae 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 nepialidm seem to have but few characters in common. The larvte it is true 

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



In Zeuzera, Cossus, No. 104 and ffeplalus (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 antenn.^, with long pectinations about one half their leno-th. In the Q 

 they are simple but woolly at the base. They have no tongue, and appai-entlv no palpi. 

 1 he larva IS an internal feeder. " 



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

 tion IS very different and rather complicated. The antenna are ^pectinate, or rather 

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

 two in number, are distinct, ti-iarticulate, rather stout. Tongue wanting. 

 My 104 IS a Cossus, with bipectinate a«tennse, and some difference in the neuration of
