Since the preceding account of the Diptera was pubhshed, a small additional 

 series of specimens has been obtained and handed to me containing about sixteen 

 additional species. The most remarkable of these is the wingless Dolichopodid I have 

 described on page 8i as the type of a new genus. Some of the others are evidently 

 introductions, and with my present limited acquaintance with exotic Diptera I do not 

 feel justified in regarding them as new, especially in such groups as Tachinidae or 

 Sarcophagidae. It is rapidly becoming impossible for a single worker to obtain an 

 adequate knowledge of all families, and in the investigation of the Dipterous fauna 

 of any country in the future, the aid of specialists who devote themselves to single 

 families will have to be called in. In the present instance this plan has been partially 

 resorted to, and we are much indebted to Dr Speiser for his careful working out of 

 the Hippoboscidac, to which I referred briefiy on p. "]"]. His report is given below 

 (pp. 86— 92). [P. H. G.]

Hab. Oahu, Honolulu, two specimens, June and July, 1900. I have compared 

 these examples with others so named in the British Museum, and find them to agree in 

 every respect. 



(2) .'' Genus and species. 



A specimen taken on the Mts. of Honolulu in 1900, appears to be very near 

 Acanthina Wied., but as the antennae are broken off it is difficult to ascertain its 

 correct position.
