ENTOMOLOGICAL NEWS. 



[Jan 



some larva of about middle size, i. e. about 5-6 mm., were 

 fouud. I could find but few of the midges. These were cling- 

 ing to the under sides of leaves of bushes bordering the stream, 

 or were slowlj' flying about. I saw a female catch a small fly 

 and eat it. Saw none in eopulo or ovipositing. 



Between June 9th and July Ist I visited the stream often, 

 searching for the eggs, but in vain. The imagines were very 

 scarce. I could find but one or two during an hour's searching. 

 There were no larvaj nor pupte left. 



Some reference to the food habits of the imagines will be 

 made in connection with the account of the mouth parts. 

 But I have little else to tell about the life- history. The rest 

 of the story is yet to be learned. 



Anatomical Notes. 



The larva. The curious shape of the larva is well shown 

 by the illustration (fig. 508) in Comstock's Manual. But Prof. 

 Comstock is in error in explaining the chai-acter of the seg- 

 mentation of the body. The body (see Fig. 1, A) consists of 

 six parts, separated by distinct constrictions. By making 

 sagittal longitudinal sections through the body it can be 

 seen that the anterior, apparently single, segment is 

 composeil of the fused hea<l and three thoracic segments,
