In my balsam mounts of the pupal exuviae of D. wait Hi I 

 failed to see the respiratory filament. In a pupa of Diamcsa. 

 which I believe to be D. waltlii, recently collected in Cascadilla 

 Creek on the rocks near the falls, the filaments are visible as 

 delicate colorless tubes as described by Muttkowski for D. mcn- 

 dotae. In other particulars, including the arrangement of the 

 marginal setae on the lateral carina, Muttkowski's description 

 of D. tnendotae applies equally well to D. waltlii.

In former years the writers, jointly and separately, published 

 a number of papers in ENTOMOLOGICAL NEWS bearing on the 

 insect fauna of North Carolina, giving lists of species in cer- 

 tain groups, distribution and seasonal notes, as indicated by 

 our records. We were avowedly accumulating data on the 

 insect life of the State as a whole. We believed that this was 

 desirable, as no such study had been undertaken in any neigh- 

 boring state, and we considered that the variety of conditions 

 presented in North Carolina, render it a "Key" state to the 

 general insect fauna of the southeastern group of states. 

 Florida is an exception for obvious reasons. 



From time to time we have received inquiries regarding this 

 work, the methods and progress. 



The collections and records have steadily increased in volume, 

 in interest and we believe in scientific value. They are a source 

 of continual reference and study. And after twenty years we 

 are making better progress than at any time in the past. 



In 1915 "A Study of the Insect Fauna of the State. -etc," 

 was formally listed as one of the permanent projects of work
