ENTOMOLOGICAL NEWS. [May, 'o2 



pean species, showing moth, larva and mine, and as soon as I 

 saw them I felt sure the identification of my chestnut miner 

 was at hand. I got down my jelly glass and found a dozen or 

 more small oval cocoons of rather tough texture and covered 

 wdth particles of earth ; upon opening some of these cocoons I 

 found some of the larvae had dried up and others had pupated 

 and then dried up. Only one or two were alive ; these I care- 

 fully put away, hoping to get the moth later, but at this writ- 

 ing all are dead, so it will be impossible to prove the species 

 this year. 



During the past few months I have been making a critical 

 study of the pupae of a number of Tortricidae bred last year and 

 sought the aid of Dr. Packard's first part of his "Monograph 

 of the Bombycine Moths." On page 62 of this work is shown 

 the pupa of European Micropteryx piirp^irella. It also looked 

 familiar, and I placed under the microscope the pupa of one of 

 my chestnut miners and the mystery was solved. 



If Dr. Packard's drawing had been made from my pupa it 

 could hardly have shown a more striking likeness. All the 

 limbs and organs are free, and across the front, just below the 

 eyes, are the enormous cutting mandibles, the labrum is cleft 

 on the lower edge and bears eight setae ; on the epicranium are 

 also four long setae ; all of these setae are fully as long as half 

 the width of the pupa. On the square clypeus are the curious 

 filamentarious tentacles referred to by Packard. 



I succeeded in softening up one of the dried larva and inflated 

 it and give the following brief description: 5 to 6 mm. long, flat- 

 tened; segments 5 to 7, broadest, tapering to a narrow point 

 at anal extremity ; head small, brown, somewhat like that of 

 a Neptiada ; no pro-thoracic shield, but a small brown anal 

 shield ; apodous. 



I am at work on a detailed description of the pupa and larva 

 and will make enlarged drawings of all details, but will defer 

 publication until I can get fresh specimens to compare. 



In Tutts' work, referred to above, Vol. I, p. 129 et seg., is a 

 most elaborate account of the European members of this group, 

 citing the papers of Chapman and Waller, who have been 

 the foremost investigators in this family. Mr. Tutt divides the 

 group into two distinct and separate super-families : Microp- 

 terygidae and the Eriocranidae. The former includes the species 

 whose larvae feed on wet moss, and the latter those species
