that he had had the same experience with them. The larvae 

 stripped the leaves to the midrib. 



A colony obtained on August 26, 1902, and placed within a 

 rearing cage molted on August 28 in clusters, leaving the shed 

 skins in conspicuous masses attached along the twigs. The 

 pupae were formed in the earth several weeks later. 



10. A Few Fragments on Anasa tristis De Geer (Hemip.). 



The following miscellaneous notes were taken at Paris, 

 Texas, in 1904. On June 7, a male of the Tachinid Tricho- 

 poda pennipes was reared from an adult female tristis which 

 had been captured on May 15 and kept in confinement. The 

 puparium of the fly was formed about an inch below the sur- 

 face of the soil in the rearing jar. The host died on May 23; 

 its abdomen was empty as found by dissection. Mr. C. T. 

 Brues identified the parasitic fly. Its maggot made no visible 

 exit through the body of its host. In seven egg-masses of 

 tristis collected in the field from squash plants between May 

 30 and June 11 there were 27, 13, 12, 20, 18, 29 and 34 eggs 

 respectively; these masses were either on the under or upper 

 surfaces of the leaf, but most of them on the under surface; 

 one mass was on the stem of the plant. A female dissected on 

 June II contained in her ovaries 40 eggs, many of which were 

 imperfect and pale ; they filled the entire abdominal cavity. 



Some eggs deposited by a female early in the morning of 

 June 2 hatched on June 8 about noon, or after a period of about 

 seven and three quarter days ; ten eggs deposited at two o'- 

 clock of the afternoon of June 20 hatched about noon, June 

 29, or after eight days, twenty-two hours. A third lot of 

 eggs laid during the night of June 21-22, hatched late p. m., 

 June 30, or after about nine days. 



When hatching the nymph of this species rises perpen- 

 dicularly from the exit hole in the end of the egg; before the 

 apex of the abdomen leaves the latter, the pinkish appendages 

 commence to spread and by the time the abdomen has been 

 extricated, the bug pushes itself from the egg and immediately 

 walks weakly away. The exit-hole is opened merely by push- 

 ing aside a shield-shaped lid whose presence is not visible
