788 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



We add the following description of the larva and pui)a: 



Larva. — Length when full-grown 520'""', cylindrical, slightly tapering posteriorly^ 

 and quite stout, of a dull greenish yellow color, somewhat paler heueath, with a nar- 

 row 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 the 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 irregu- 

 lar row of black points across the anterior side. 



Pupa. — Length 11""", robust, light 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 fourth 

 abdominal segment. (Comstock, Ag. Rept. for 1880.) 



121. The Silver-pine Tortricid. 



Grapholitha hracteatana Fern aid. 



Order Lepidoptbra; family Tortricidae. 



Infesting the cones of Abies bracteata, a small Tortricid larva. After transforming, 

 the pupa protrudes itself nearly two-thirds of its length, and from this emerges a, 

 small dark-colored moth with white and metallic markings. 



"On the 14th of August, 1880, cones of the Abies hracteata were sent 

 to this department by Mr. George R. Vasey, from Jolon, Cal., one of 

 which was infested with Tortricid larvse. Three of the moths emerged 

 on the 13th of September, 1880, one on the 15th, and another on the 

 20th. 



"The seeds of this cone, as well as those of others sent at the same 

 time, were infested with Cecidomyid larvae. The Tortricid larvse 

 worked only in the scales of the cone, while the Cecidomyids were con- 

 fined to the seeds. 



"Mr. Vasey, who sent the cones, states that 'the Abies bracteata Nutt., 

 locally called silver pine, extends from the northern boundary of San 

 Luis Obispo County 40 miles northward, in canons on both sides of 

 the Santa Luca range. It is a handsome and striking tree, 100 to 150 

 feet high, in shape pyramidal, with an elongated peak. The white 

 under surface of the leaves produces a silvery sheen when the sun shines 

 upon them at the right angle.' " 



"The following description of this moth has been written for this re- 

 port by Prof. 0. H. Fernald : 



Head, palpi, thorax above, and basal third of forewings dull ocher yellow, inclin- 

 ing to cinereous on the thorax and base of the wings in certain lights ; last joint of 

 palpi very small, somewhat darker; legs, thorax, and abdomen beneath straw-yellow ; 

 outer side of the tibiae and the basal portion of each joint of the tarsi pale cinereous. 



Forewings exteraally ocher yellow, overlaid with dark-biown scales. Costa marked 

 with fine geminate white spots, from which are continued metallic blue stripes. The 

 first costal spot begins a little before the middle, the second a little beyond the mid- 

 dle, the others following at about equal distances from each other towards the apex, 

 alternating with and cut by dark brown, the third and fourth not geminate in some
