New or Little-Known Crane-Flies from the Hawaiian Islands 
(Tipulidae, Diptera). 
BY CHARLES P. ALEXANDER, AMHERST, MASS. 
(Presented by Mr. Bryan at the meeting of June 3, 1922.) 
The following records are based on a collection of Tipulidae 
kindly sent to me by Dr. James F. Illingworth. The types and 
uniques are preserved in the collection of the Bishop Museum, 
Honolulu. The chief papers dealing with the Tipulidae of the 
Islands are the following: 
Grimshaw, Percy. Fauna Hawaiiensis, vol. III, pp. 6-10; 
1901. 
Alexander, Charles P. Notes on the Crane-Flies of the 
Hawaiian Islands. Annals Ent. Soc. Amer., vol. XII, 
Pp zoe LOTS, 
It now appears that the species of Limnobia, Styringomyia, 
and Trimicra are more widely distributed than was believed 
at the time of their original characterization in 1901. The 
numerous species of Dicranomyia, on the other hand, all seem 
to be endemic. The same is true of the single species of Gono- 
myia known from the Islands. 
Limnobia perkinsi Grimshaw. 
The following localities are represented: 
Oahu: Honolulu, October, 1919 (E. H. Bryan, Jr.). 
Fijt: Rewa, March, 1906 (F. Muir). 
The species is now known from other Pacific Islands as 
Samoa and Tahiti. In previous papers, the writer had consid- 
ered this species as being more properly referable to Libnotes. 
Following the definition of the latter genus as diagnosed by 
Mr. F. W. Edwards, the present species is to be retained in 
Limnobia. 
Dicranomyia stygipennis Alexander.
