ly in many respects. These insects must be handled very carefully when 

 they are taken, as the labial palpi are easily detached even whilst they are 

 living. 



T. alacella. — Labial palpi second joint orange-yellow, terminal joint tinged with 

 fuscous. Head deep brown above, irridescent. Face shining pale yellow. Anten- 

 nae deep brown. Fore wings deep brown, witli a steel-blue, shining streak along 

 the costa, extending from the base to an orange-yellow costal spot at the begin- 

 ning of the apical cilia, and deeply excised in the middle of the wing. Beneath 

 the excised portion and near the inner margin is a short, steel-blue streak, and 

 the costal streak emits a slender line to the inner margin, opposite the costal or- 

 ange-yellow spot. Hind margin with a series of steel-blue dots. Cilia brown. 

 Hind wings fuscous, cilia a little paler. 



Taken on wing 17th of July. 



SOLENOBIA? Zeller. 



In the hind wings the costal vein is well developed and placed close to 

 the costa. The subcostal vein is simple, giving rise near its middle to an 

 angulated discal vein which sends off a branch to the margin beneath the 

 tip and receives the discal fold at its angle. The median subdivides into 

 four hranches^ the tiro sujicrior hranrlies having a common o)-i(/in, the 

 others short and equi-distant. 



The subcostal vein of the fore wings sends off a long, decided marginal 

 branch from the basal third ; about the middle of the wing forms a long, 

 rather large secondary cell, from the hinder end of which arise two mar- 

 ginal branches, and from the point where the lower branch of the second- 

 ary cell enters the discal two other branches arise diverging from their 

 origin, one to be delivered above and the other beneath the tip. Opposite 

 the discal fold arises another branch running to the maro-in beneath the 

 tip and the median vein subdivides into three nearly equi-distant, short 

 branches, the posterior of which is nearly perpendicular to the inner mar- 

 gin. The submedian is short and furcate towards the base for half its 

 length. 



Head liairy above and in frontj without ocelli. Eyes small, spherical, 

 slightly naked above. Cephalic stigmatne very large and distinct. An- 

 tennte setaceous, scaley and tufted slightly above towards the end, ciliated 

 beneath. Max illari/ palpi, lahial palp}i and tongue undeveloped. 



S ? Walshella. — Head and face dark gray. Antennte dark gray, slightly spotted 

 with wliite. Fore wings pale gray, varied with fuscous sprinkled over the surface, 

 without defined markings, except along the costa near the tip, where there are a 

 few pale grey or whitish s^jots. Cilia gray. Hind wings gray. 



I received a specimen of the above insect sometime since from my es- 

 teemed friend Benj. D. Walsh of Rock Island, 111., who was compelled to
