REPORT OF THE ENTOMOLOGIST. 237 



In tlie latter part of August, individuals of the second brood wore 

 very abundant in tlie scrub-pine in the vicinity of Washington. As 

 before, they were found in almost every stage of growth, and the ditl'er- 

 cnce was even more marked. In one instance five larvae of greatly dif- 

 fering sizes were found in one shoot. The smaller ones were boring 

 into the bases of the leaves, and the larger ones into the twig proper. 

 The largest of the iive had made quite a long channel from the tip of the 

 l)ud down into the heart Of the twig. Pupae were also found at this 

 time, which did not give forth the moth until late in the winter. 



The usual mode- of hibernation is in the pupa state. A thorough search 

 in January in the field showed only pupae. The pupae collected in Au- 

 gust and September did not begin to give forth the moths in the breed- 

 ing cages before early January, though this was continued at intervals 

 through January, Februaiy, and March, and was greatly hastened with- 

 out doubt by the heat of the room. On Fel>ruary 15, however, a few 

 twigs were collected, from one of which, on February 28, a full-grown 

 larva had emerged and was found crawling about the cage. This would 

 seem to indicate occasional larval hibernation. 



As to remedies, the only one which I can suggest at present is that 

 involving the somewhat arduous task of picking oli" the infested twigs in 

 early winter and burning them. Whether the salvation of the trees will 

 be 'worth this labor in greatly infested regions will depend entirely upon 

 their value to those interested. 



As Mr. Scudder has prepared descriptions of all stages, we will not 

 trespass upon his ground by appending further descriptions than we 

 have already given. Our figure will assist in the recognition of the 

 ei>ecies. 



THE PITCH-PINE EETINIA. 



(Betitiia rigidana Fern aid [new species].) 

 Order Lepidopteea ; family Tortricidae. 



Inbaliiting terminal shoots of Pinus rigida, and of similar habits to the Frustrating 

 Ketinia, a gray, brovrn, or blackish larva S"""" (i- inch) in length, -which in its jier- 

 fect form becomes a small moth with dingy white wings, marked with dark red and 

 silvery gray. 



In the summer and fall of 1879, Mr. S. H. Gage, of Ithaca., N. Y., sent to 

 the department specimens of the pitch-jjine containing Tortricid larvae 

 and i)upae, which in their work resemble Betima frustrana, hnt differ 

 from that insect in coloration and in being slightly larger. These de- 

 veloped into a moth ijitermediate in characters between R. fmstrana and 

 JR. Comsioclcianaj and which has been described by Prof. C. H. Fernald 

 as follows : 



Eetixia rigidana Fernnld (n. sp.). 



Head sordid white, with a yellowish tinge ; front and palpi inclining more to ashy ; 

 antennae brown, annulated with wliite ; thorax above very light gray, washed with 

 dull ochreous, deepening to a coppery tint oji the fj-ont of ide i)atagiae. 



Thorax beneath, abdomen and Laid wings alcove and beneath, and fore wings be- 

 neath light gray, with a 8ilky luster ; fringes of the hind wings lighter, with a line 

 near the base concolorons with the wings. 



Fore wings above sordid white, with a basal patch occnpylng the basal fourth of 

 tlie wing, composed of about four irregular cross-streaks of dark red, alternating with 

 fiinular streaks of silveiy gray, the outer red streak sending out a tooth on the fold. 

 The light space following the basal patch has several small gray costal spots, from 

 which light ocherous streaks extend across the wing. A dark-red bmul extends acrosi? 

 thp wing beyond the middle, divided on tlie cow(;i ''v ?, !.;i'i:iii,;''i' iv^itr ^•.•)!.. l!:'-.-,-.
