back and forth in its tropical home just at dusk or even 

 at mid-day if the place was shady, I have never recognized 

 its larva, which is said to feed on Legumes. 



HYPENHXE 



These moths, or part of them, are sometimes put in the 

 Noctuidas. They are commonly called Deltoids because 

 the outline of their wings, when at rest, is frequently tri- 

 angular like the Greek capital Delta; also Snout-moths 

 because the palpi of many species are enlarged and so held 

 as to resemble a beak. For the most part, the adults are 

 dull colored, obscurely marked, and not likely to arouse 

 comment by any but the collectors, and even they have 

 not been enthusiastic, although these moths come readily 

 to light and sugar-bait. However, they have their in- 

 teresting points. Secondary sexual modifications are 

 common, the males frequently having wings, feet, antennae, 

 or palpi shaped differently from those of their mates. 

 The larvae of Epizeuxis americalis have been found in the 

 nests of ants (Formica rufa); it and some of its relatives 

 seem to prefer dead leaves to living. Hypena hurnuli 

 is frequently injurious to hops. In July, Mr. Grossbeck 

 found a swarm of adult Epizeuxis lubricalis (Plate LV) in a 

 hollow tree. The larvae feed on decaying wood and, 

 probably, also on grasses; they are usually found under 

 chips. 



NOTODONTID.E 



The adults superficially resemble the Noctuidae. They 

 come freely to light and often to sugar-bait. The larvae 

 have no claspers at the hind end of the body and so they 

 more generally wave this portion in the air than do other 

 caterpillars; sometimes the anal segment has a pair of 

 fleshy projections but these seem to correspond rather to 

 humps on other segments than to prop-legs. The pupae 

 are usually naked.
