mens from various parts of the country, where the larva has been boring 

 in rose. He also states that there is probably no doubt as to my speci- 

 mens being the same as Riley's S. pyricolana. 



" Miss Murtfeldt found the larva damaging apple terminals in Mis- 

 souri in August and September, i8go, and gives an excellent description 

 of the larva and moth. This is the only published reference to the species 

 so far known. 



'■'■Larva. — 5 x 1.25 mm. Elongate, sub-cylindrical; colour from a 

 dirty cream to light yellowish-brown, tinged with pinkish dorsally— usually 

 giving it quite a rose colour, tubercles grayish, spiracles brown ; head 

 slightly narrower than prothorax, metathorax to 7th abdominal segment 

 of same width, thence tapering sharply caudad ; head shining, front cinna- 

 mon brown, sutures darker with blackish line, an indefinite caudo-mesal 

 area slightly darker and a similar darker shade on each dorso-lateral sur- 

 face caudally, joining on caudal margin under pronotum ; labium and max- 

 illa body colour, sutures of under side of head dark, palpi and antennse 

 light, latero-ventral sutures of head black, ocelli black, forming a short 

 black bar extending caudo-dorsad back of antennse, labrum dark brown ; 

 abdominal segments with two and thoracic with three annular ; pronotum 

 chitinous, straight, cephalic margin covering caudal part of head which is 

 visible beneath, caudal margin curved, surface shining ; legs with basal 

 suture in front dark, otherwise concolorous ; tips of prolegs dark brown ; 

 the 8th abdominal segment, especially on the caudal annulet, giving it a 

 darker, olive colour, the 9th abdominal targite chitinous, shiny, olive 

 colour ; caudal seta3 prominent, long as the ninth segment ; anal prolegs 

 cylindrical, reaching to the tip of the ninth segment, brown at tips ; four or 

 five stiff brown setaj above anus ; segments of abdomen rather longer 

 caudally." 



Larval Mouth-parts. — The under side of the larval head is shown in 

 figure 4. I have been unable to homologize the sclerites at the base of the 

 labium and maxillaj ; ca is evidently the cardo of the maxilla, in two parts ; 

 c may also be a part of the cardo ; a and /; may form one sclerite, though 

 there is a distinct suture between them ; d forms a band connecting h on 

 either side (this same sclerite is found in Coleopterous larvi^, and seems to 

 be the ventral sclerite of a head segment) ; e is membranous, and in it lie 

 chitinized sclerites g and f. From g the occiput (?) i runs dorsad, the 

 portion /of the figure being the break caused by the detachment oii from/ 

 Qn the slide j j is distinct from h^ and caudally there is a distinct suture
