May 21, burrowing in the branches of the Pignut Hickory {Carya 

 Porcind) usually selecting the lower branches; imagoes about 

 June 22. Clirysalis. — Of the usual form, pale brown, rounded at 

 the posterior end, at which place there is a cluster of about 4 

 slender hooked spines ; length, from 7 to 8 mm. The larva spins 

 a thin web around the footstalks of the leaves which grow near 

 the terminal end of the branch, and then burrows into the termi- 

 nal bud and the wood of the present year's growth. It webs its 

 castings together and forms a short tube which projects outward 

 from the mouth of its burrow, and is closed at the outer end. 

 The larva probably assumes the chrysalis form in its burrow, but 

 those which I reared deserted their burrows and spun tough 

 cocoons beneath the litter in the bottom of the breeding-cage. 

 These larvae are very subject to the attacks of parasites; from a 

 small number which I collected I obtained three moths and two 

 Hymenopterous parasites which Mr. E. T. Cresson determined 

 to be the PJianerotoma Tibialis of Haldeman. One of these 

 parasites issued June 21 and the other June 26. 



ACROBASIS Angusella, Grote, N. Am. Ent. i, 51, 

 This species has a continuous black dash on the imderside of 

 the secondaries along costa. The thorax and base of forewings 

 are dirty reddish. The transverse anterior line is curved ; the 

 posterior line is denticulate. The lines are oblique and uneven. 

 \n A. Carycs they are perpendicylar. Acrobasis AngvseUa has 

 been reared by Mr. Akhurst from larvae boring into the leaf 

 stems of the hickory. The dash is less vivid in the following : 

 Acrobasis Demotella, n. s. 



$ This species has a shorter black mark on secondaries be- 

 neath, not connected with the base of the wing, and a narrow 

 basal streak along median vein. Forewing fuscous; base pale, 

 stained with reddish, with an ashen shade on internal margin in' 

 place of the usual scale ridge. Outer line obliterate, pale, sinuate, 

 not dentate as in Angusella, followed by a vague, reddish shade. 

 Head and thorax whitish with a faint reddish tinge. Hind wings 

 pale fuscous with paler fringes. Expanse, 24 mil. West Farms, 

 Mr. Angus. This differs, as above noted, from Angusella, as a 

 variety of which I considered it in my original description of 

 that species. It must be considered distinct since Angusella has 

 been reared by Mr. Akhurst, whose specimens agree with my 

 type. The head and thorax are nearly white in Demotella. the 

 larger and brighter of the two forms; the peculiar black dash on 

 hind wings is not so bright and does not continue along costa to 

 base. The habit of the larvae of Demotella is unknown to me. In 

 the PJiycidce it is necessary to have the male in order to correctly 

 refer the species. No descriptions should be made from the 

 female alone.
