AFFECTING THE PINE. 



THE PINK OAKIPETA. 



(Caripeta angmtioraria Walk.) 



This is frequently met upon the white pine (Pinus strobus) in An. 

 and September throughout the New Ed gland States, and as late as the 

 first week in October in Rhode Island. Specimens become full-fed by 

 the 8th of August in .Maine, and before entering the chrysalis state spin 



a whitish web, with minute meshes, not a loose web. On the day follow- 

 ing the chrysalis appears, and the moth appears in May and June of the 

 following year. It is one of our most showy geometrid moths. 



The larva. — Body rather large and thick, thickest on the segment hearing the first 

 pair of abdominal legs. Head nearly as wide as the prothoracic Begment, very 



slightly angulated on each side of the vertex, mottled with dusky spots or marbled 



with transverse, parallel waved lines. The prothoracic segment rather small, not an- 

 gulated in front, provided above with small warts. On each abdominal segment a 

 high, transverse, prominent, smooth ridge, somewhat saddle-shaped and bearing at 

 each end a piliferous wart. On the third and second segments from the end no such 

 ridge these being replaced by piliferous warts, the two on the penultimate segment 

 heingrather high and situated near together. Behind these two tubercles on a trans- 

 verse wrinkle are two small dark warts, and on a succeeding wrinkle are six warts. 

 Outhe supra-anal plate are four warts, and on the end, which is obtuse, are four small 

 hair-bearing warts. There are similar hairs on the edge of the anal legs, which have 

 a deep crease parallel to the front edge ; the lateral ridge is large and rough and inter- 

 rupted at the segments. The body elsewhere is variously tuberculated, with hairs 

 arising from the warts. The body in general is pale whitish-gray, with a lilac tint or 

 slate color, variously marbled with dark-brown and sometimes with a decided reddish 

 tint. Length 32 mm . 



Pupa. — Rather stout. Brown, with an obscure dorsal row of irregular spots form- 

 ing a nearly continuous line or band : a lateral row of large, obscure spots : second 

 abdominal segment from the end of the legs with two warts beneath. Length 15 inm . 



The moth. — It differs remarkably from any other species of the family by the rich, 

 opake, velvety, ochreons fore wings, with the three broad silvery lines and large dis- 

 cal dot. The head, antenna?, and thorax are pale ochreons. Fore wings opake. deep 

 ochreous, paler at the base : on the inner fourth is a white line forming a single large 

 and acute angle on the median vein, along which it is prolonged beyond the basal 

 third of the wing, extending out nearly as far as the discal dot, though situated be- 

 low it. There is a large, irregular, silvery- white discal dot and just beyond a 

 broad silvery line, diffuse on the outside; it curves inward just below the median 

 vein and slightly inward opposite the discal dot. Halt-way between this line and the 

 outer edge of the wing is a row of irregular white spots, from which sometimes run 

 whitish streaks to the fringe, Which between the white spots is oehreous-brown. 



The hind wings are pale whitish-ochreous above : beneath, washed with yellow-ochre- 



ous npon and on each side of the venules. Expanse of wings :'.('. -'■■•'" (1.60 Lnch<

 THE OAK-LEAF CRYPTOLECHIA. 



(Cryptolceltia schlagenella Zeller.) 



This is a remarkable insect, both as a caterpillar and moth. It is not 



uncommon in the larval state on the oak. where we have seen it in Maine
