142 FIKST ANNUAL EEPORT OF THE STATE ENTOMOLOGIST. 



An enlarged view of the egg, represented in accordance with the 

 above description, is given at g in Fig. 34, in connection with other 

 phases of the insect. For the use of the figure, I am indebted to the 

 Department of Agriculture at Washington, it having been one of the 

 illustrations of the Report of the Entomologist for the year 1881-83.

The Young Larvae. 



Some of the eggs which I took on September 1st, from the sod, and 

 placed in vials for convenience of observation, gave out their cater- 

 pillars on the 7th. They were supplied from time to time with fresh 

 and tender grass, in which they ate irregular holes, but without any 

 evidence of appetite. All but one died within two or three weeks. The 

 single survivor, after feeding sparingly, at long intervals, underwent a 

 molting about September 15th. The greater part of the time was 

 passed at rest, and whenever the drying of a blade of grass gave it a 

 cvlindrical form, the hollow thus made was chosen for its resting place. 



The appearance of the young larva, a fortnight after its molting, 

 when so little progress had been made in growth that it did not exceed 

 one-tenth of an inch in length, was as follows : The head was elongate 

 and shining black, with some white hairs projecting forward about one- 

 half the length of its diameter; collar broad and shining black. Body 

 dark brown, with a long lateral white hair on each segment, longer 

 than those on the head and exceeding the diameter of the body ; 

 gradually tapering backward from the first segment ; on each segment* 

 two subdorsal verrucose spots. 



Without farther progress, the larva died during the month — the
