edged outwardly witli liglit gray. iMiirgiiial line black, broken. Hind wings dark 

 fuscous. 



Fla., Texas. Probably everywhere in East and South. 



The determination of this insect as above is I think the correct one. 

 Zeller's type was smaller than the type of dihcctilella, Grt. , but the figure 

 Zeller gives, and the type in the Cambridge Museum allow no other de- 

 termination as it seems to me. There is a great deal of variation in the 

 depth of coloring in the species, and diliiculella might stand as a varietal 

 name for the form with the black basal field. The insect is 2-brooded 

 in Texas and the varieties incline to be seasonal, dilucukUa being the 

 larger and darker Summer brood. Tallcolalis is a synonym of the type 

 form. 



Prof Comstock, in Dept. Agric. Report, i8So, gives a history of 

 the insect as follows : 



" Zrt'rz'rt.— Length when full grown 20 mm., cylindrical, slightly tapering 

 posteriorly and quite stout, of a dull greenish yellow color, somewhat paler beneath, 

 with a narrow black stripe on each side about twice the width of the last, and equally 

 distant from it and the middle of the dorsum. This stripe extends from the thoracic 

 to the anal plate. The head, thoracic and anal plates are of the same ground color 

 as the body. Eyes and end of mandibles black ; several irregular black bands on 

 each side of tlie head, extending from the posterior side forward to about the middle: 

 thoracic and anal plates with a few scattered brown dots, the latter with an irregular 

 row of black points across the anterior side. 



/"zir/rt. — Length 11 mm., robust, li^ht brown, rounded at both ends, the posterior 

 armed with a cluster of fine hooks ; the abdominal segments are covered with coarse 

 punctures except on the posterior edge. Wing covers extend to the end of the 4th 

 abdominal segments." 



"Some of the terminal twigs of pine {Finns faeda) infested by the 

 larvae of this insect where collected by myself in January, 1880, near 

 Jacksonville, Fla. The appearance of these infested twigs is somewhat 

 striking ; the leaves around the end are loosely held by threads of silk, 

 which also holds the excrernents of the larva in a more or less irregular 

 mass, varying from i to 3 inches in length and from i to 2 in thickness. 



The larva is about eight-tenths of an inch in length, rather stout, of 

 a greenish yellow or drab color, with two very distinct, quite broad 

 black dorsal stripes, and a narrow one on each side. 



When mature the larva descends to the ground, where it spins a 

 loose cocoon of yellowish brown silk, to which is attached a covering of 

 grains of sand or other loose materials, and withm which it transforms 

 to a pupa, in which state it passes the winter. 



The moths from the larvae mentioned above emerged during the 

 following April." 



Taken in Texas in April and Aug. arid consequently two-brooded.
