the two ridges bounding it not being very distinct, but nearly obsolete. 

 From the plateau, which is rather broad, the sides fall off at a moderate 

 slope to the edge of the body. The width of the plateau is about the 

 same as the body on either side. The body is pea-green, tinged with 

 yellow in front. The second thoracic segment or front of the body as 

 seen from above is mostly bright brick-red (Rubens' madder red), becom- 

 ing darker in the middle ; the red extends on each side to the front edge 

 of the segment behind, and extends back to the great central reddish 

 patch ; it encloses a rather large, green, sunken, rounded wart, and two 

 smaller, less distinct ones behind. There are no hairs or bristles on the 

 body. The great central patch consists of a large central orange or pale 

 Venetian-red spot extending along the plateau and including four median 

 oval, round, sunken warts, with a flattened button-like warllet in the 

 centre, and four oval warts which are depressed and acute at the smaller 

 end, each pair alternating with the median areas. This brighter red pla- 

 teau spot is surrounded by a large pale purple madder patch forming a 

 spot of the shape of an irregular Greek cross, which sends a broad arm to 

 each side of the body, reaching to and including the side of the lateral ridge 

 just above the creeping disk. The same patch sends a broad, triangular 

 posterior arm along the plateau, spreading out each side of it to the end of 

 tlie body and ending in a sharp point, which is at the foot of the cross. 

 The entire cruciform patch is edged with carmine red, and outside of 

 that, especially behind, with lemon-yellow. 



Larva of Heterogenea (Tortricidia?). 



Occurred on Vaccinium. Length, 9 mm.; width, 4.5 mm. In outline 

 seen dorsally to be oval-elliptical and produced behind into an upturned 

 point, which is obtuse at the end, with two seliferous tubercles. The 

 surface of the body is round and irregular, the back is raised into two 

 great, longitudinal, irregular, fleshy ridges, witli large, fleshy tubercles 

 of the same color, bearing short, stiff, dark setae which are pale at base 

 and black at tip. Each of these ridges is irregularly stained with pale 

 yellow. There are also two similar lateral ridges, the lowermost forming 

 the edge of the creeping disk. They are broken up into a series of coni- 

 cal, setiferous, fleshy tubercles, but are not stained with yellow. The 

 body is pale pea-green, the surface of the skin finely granulated. There 

 are no reddish murks.
