46 MAINE AGRICULTURAL EXPERIMENT STATION. 1917. 



leg scarcely reaching the level of the glazed eye-piece in some 

 species and extending farther cephalad in others ; mesal length 

 of prothorax one-half that of the mesothorax ; metathorax one- 

 fifth the length of the mesothorax and shorter than the first ab- 

 dominal segment ; mesothoracic spiracle slit-like ; abdominal 

 segments 1 to 8 punctate ; furrow present on the dorsum between 

 the ninth and tenth abdominal segments, the caudal margin 

 coarsely toothed, the lateral extensions reaching almost to the 

 base of the cremaster ; cremaster longer than the tenth segment, 

 bearing two stout curved spines at the distal end, with slender 

 hooked setae along each lateral margin, the ventral surface with 

 two deep parallel furrows, one near each lateral margin. 



The species of Sabulodes may be separated as follows : 



a. Face-parts with a prominent transverse ridge between 



the eye-pieces ; body setae arising from small papillae ; 



caudal margin of furrow between the ninth and tenth 



abdominal segments with small projections or teeth. 



transversata. 



aa. Face-parts never with a prominent transverse ridge be- 

 tween the eye-pieces ; body setae arising from small de- 

 pressions ; caudal margin of the furrow between the ninth 

 and tenth abdominal segments with large projections. 



lorata.

. Color yellowish brown, the spiracles, tenth segment, and 

 cremaster always darker brown, an irregular dark spot on each 

 side the dorso-meson of the first eight abdominal segments and 

 one on the mesothorax at about the middle of its length, also 

 fine irregular blotches on other parts of the body which are 

 exceedingly variable; antennae more elevated than the other 

 appendages, highest along the middle line, the surface covered 

 with small tubercles ; abdominal segments 1 to 8 densely punctate 

 with medium punctures, the ninth and tenth segments smooth; 

 body setae arising from small pits ; abdominal spiracles with 

 the openings elliptical ; spiracular furrows never present ; dorsal 

 furrow between the ninth and tenth segments edged with black 

 or very dark brown, with four prominent teeth on each side
