348 LEPIDOPTERA. 



nearlj^ full grown tliey cover the grains "vrith a very thick web. 

 According to Curtis the larviB retire to cracks and crevices in 

 the floor and walls of the granary, and construct their cocoons 

 by gnawing the wood and Avorking it up with their web until it 

 has the form and size of a grain of wheat, wherein it remains 

 through the winter, changing to a chrysalis earlj' in the spring ; 

 while two or three weeks after the moth appears. It is creamy 

 white, with six brown spots on the costa, and with a long 

 brown fringe. To prevent its attacks empty granaries should 

 be thoroughly cleansed and whitewashed, or washed with coal 

 oil, and when the moths are flying numbers may be attracted 

 to the flames of a bright light ; also when the larvtB are at work, 

 the grain should be shovelled over frequently to disturb them. 



Tlie beautiful genus Adela is at once known by its exces- 

 sively long antennae. The larva makes a flat case, and feeds 

 on the leaves of various low plants, such as the wood Anemone 

 and Veronica. The A. Rklmg^eUa of Clemens has coppery 

 brown fore wings, with a pale grayish brown mesial patch 

 dusted with black, and four or five black spots at the inner 

 angle, while the hind wings are fuscous. 



Hijporiomeuta has a smooth head, with rather short, slender, 

 reflexed, subacute labial palpi ; the fore wings are white, dotted 

 in rows with black, and on the base of the hind wiugs is a 

 transparent patch. The larvffi are gregarious, and the pupa is 

 enclosed in a cocoon. H. miUepunctatella Clemens is white, 

 with the base of the costa blackish, and with lougitudiiml rows 

 of distinct black dots, two of which, one along the inner mar- 

 gin, and one along the fold, are plain. The hind wings are 

 blackish gray. 



In D(qvessaria the fore wings are unusually oblong, being 

 rounded at the apex ; and the hind wings are broader than 

 usual, with the inner edge emarginate opposite the subme- 

 dian vein, and rounded opposite the internal vein. The abdo- 

 men is flattened above, with projecting scales at the sides. 

 The larvjTe of this genus are extremely active, and feed on a 

 variety of substances ; some in rolled up leaves of composite 

 plants, some in the leaves and others in the nmbels of the 

 umbelliferous plants. Many of the worms descend from the 

 plant on the slightest agitation, so that considerable caution is
