The Early Stages of Limacodes scapha Harris. 



The young live on the under side of the leaf, eating holes out of the 

 middle. 



Stige nCl) — Length, 3 mm. On Myrica gale, August 4, from Miss C. E. 

 Soule. The body is oval, much flattened compared with the full-grown 

 larva, being of the shape of a flat iron, the back being much depressed 

 instead of rising into a conical dorsal ridge as in the final stage. It is 

 square or docked in front and pointed at the end of the body. It is 

 greenish, with a slight amber-yellow tint ; but the much raised thick rim 

 or edge of the body is stained brick-red, both tlie outer and inner edge of 

 the red portion being scalloped, while a reddish bridge is thrown across 

 the depression just in front of the middle. 



Stage IV, or that before the last. — Received, August 26, from Miss 

 Soule. Length, 6 mm. ; breadth, 3 mm. The body is still much 

 broader and flatter above than in the full-fed worm ; the dorsal surface 

 is broader than the ventral, the sides overhanging the creeping disk, 

 while the dorsal surface is broad and depressed, the sides rising or turned 

 up somewhat, while the sides of the body are deeply hollowed in. The 

 body is widest in the middle where there are two large, dark blood-red 

 patches which touch each on the median line of the body. Near the end 

 on each side of the body (on the third or fourth segments from tlie 

 pointed end of the body) are two pairs of small dark-red spots, connected 

 at the base on the reddish rim of the dorsal field ; and on the first pair of 

 spots at the base on the edge of the body is a clear white dot which 

 extends underneath. The edge of the dorsal depressed surface is some- 

 what stained irregularly with dirk blood-red ; the red accentuated at 

 intervals by four or five dark-red dots. On each side of the body are two 

 alternating series of round areas, as if stamped into the skin. On each 

 side of the body below are two rows of somewhat similar roundish im- 

 pressed spots. On each side above is a row of nine chitinous crescent- 

 shaped marks. These spots do not differ in hue from the body. The 

 prothoracic segment or hood is reddish in front and the shoulder of the 

 next segment is stained with red. The head is pale green, dark around 

 the eyes and mouth. 



The specimen described below agrees exactly with Harris' figure (Corr.
