to the ground after hanging a short time suspended by a thread. Once on the 

 ground the larva crawls under fallen leaves, etc., and pupates within the case, 

 this stage requiring from two to three weeks, the moths appearing about June 

 20 and being plentiful a week later around sheep laurel in the field. In order to 

 facilitate the emergence of the moth, the pupal case projects slightly from the 

 oval case. It is not known how many broods occur in New Jersey. Probably 

 the over-wintering larva? are those which hatch from eggs deposited during 



July. 



Kalmia angustijolia L., is frequent in sandy ground, especially around the 

 edges of bogs in the pine barrens and often covers large areas. In view of this, 

 the miner should be found in many other localities in the pine barrens. Dr. 

 Dietz writes that he has bred this species in numbers from sheep laurel collected 

 in Pennsylv^ania and has noted as many as twelve to fourteen mines in a single 

 leaf. 



Full-grown Larva. — Length 3.4 mm. Width 0.5 mm. Head and first two 

 segments brownish, remainder of body white with greenish tinge, somewhat 

 translucent; elongate, tapering slightly posteriorly; body notched at sides, 

 flattened dorso-ventrally ; head small, mouth-parts dark, first thoracic segment 

 longest, second and third thoracic segments subequal in length; abdominal 

 segments subequal in length except in the ultimate and penultimate which 

 combined approximate the length of the preceding segment; first thoracic 

 segment not quite as wide as the second and third which are subequal in width ; 

 abdominal segments subequal in width except the last three or four which are 

 narrower; prothorax bears a dorsal, dark spot which covers most of the surface; 

 dorsum of meso- and metathorax bears a somewhat similar dark area each with 

 separated, subcircular light areas. First seven abdominal segments bear 

 irregular, oval, ill-defined dark areas; dorsal markings of eighth abdominal seg- 

 ment somewhat similar to those on dorsal surface of metathorax, the subcircular 

 light areas may be fused or only slightly separated; dorsal surfaces of remaining 

 abdominal segments may bear indications of dark areas or be entirely light; 

 ventral surface and markings similar to those of dorsal surface except that the 

 dark areas on the third, fourth, fifth and sixth abdominal segments are re- 

 placed by dark, oval rings; head and sides of each thoracic segment bear several 

 fine hairs; a single hair on side of each abdominal segment; dark areas appear 

 to be finely shagreened; shagreening on prothorax more pronounced. 



Another lepidopterous miner, of sheep laurel was described by Dr. Dietz 

 in 1907 (Tr. Am. Ent. Soc. XXXIII, p. 291). This is Ornix kalmiella, the 

 larva of which makes a pale, orange coloured, blotch-like mine in the upper 

 side of a leaf. The localities for this species as given by Dr. Dietz are Pa. and 

 Conn., larvae, August and September; adults, following May.
