Pro-legs have a complete encircling row of hooks turned 

 outwards, at the extremity. Under a ^ inch objective the larval 

 skin is comparatively smooth, having the very slightest rough- 

 ness, and the hairs are smooth. 



In conclusion, I would point out the scientific importance 

 of accurate descriptions of the Australian Hepialidte. From 

 the foregoing I draw special attention to the curious black 

 concavity on the scutellum which remains until the pupa stage. 

 Its significance is an interesting problem. The hair within is 

 evidently articulated, or at any rate is movable at will of the 

 larva. Probably all the hairs are so, but I specially noticed it 

 with this particular hair. The position of the spiracles, and 

 the arrangement of the tubercles on the abdominal segments are 

 matters of importance. 



I append a note of the more important imaginal structures. 

 The genitalia of 3 figured for comparison with Australian 

 Hepialus, Antennae are simple base figured, palpi are terminated 

 by small lobes connected by a narrow neck with main joint. 

 These are covered densely with light and dark hair (scales ?) 

 Neuration of the wings, one of the most important imaginal 

 structural characters for the purpose of classification — note the 

 series of transverse nervures at base of wings and the jugum, a 

 small projection near base of fore wing on inner margin, this 

 only occurs in the Hepialidse and Micropterygidae among the 

 Lepidoptera, but also in the Trichoptera. 



Can I enlist the assistance of Australian entomologists in 

 my researches into the structural characters of the Hepialidae '? 

 I am desirous of obtaining ova and newly hatched larvae 

 (accurately labled in spirits) for observation and comparison, 

 and should be most happy to publish results through the 

 Australian societies.
