Hecalus lineatus Uhl. is one of the largest of the grass-feeding spe- 
cies. (See fig. 6.) The female measures 12 mm. to the tip of the 
exserted, attenuate ovipositor. The head is 2.5 mm. long by 2 mm. 
broad, slightly narrowedin front of the eyes, widening immediately 
to a spoon-shaped tip, which is thin and slightly reflexed. The body 
color is bright green, with four equidistant parallel lines extending

over the head, thorax, and scutellum; the nerves of the elytra and 
ovipositor are orange-red. 
The males are quite different from the females in appearance, and 
were described by Prof. Uhler as Glossocratus fenestratus, and were 
long regarded as a distinct species. They are much smaller, meas- 
uring scarcely 8 mm. to the tip of the style-like pygofers. The head, 
thorax, and basal part of the elytra are marked as in the female but 
the ground color approaches orange. The apical half of the elytra 
and the abdomen are quite different. There is a narrow black band 
just back of the middle of the elytra and a broader terminal one;
