222 Miss S. L. M. Summers on Blood-sucking 



working out certain anomalous material now in my 

 possession. 



In the meantime I would recommend that the following 

 specialized genera be regarded as the types of distinct divisions^ 

 which we may, for the moment^ regard as families : — 



T E R E B R A NT I A. 



Heterothrips, Hood (nee Buffa) (Thripid^), on account of the 

 structure and segmentation of the antennae, the character of the 

 sensoria, and the tarsal appendages. HETEROTHRiPiDiE, mihi. 



Panchcetothrips, Bagnall (Thripid^), on account of the structure of 

 the head, the abdomen, last abdominal segment and ovipositor in female, 

 and venation of fore wings. PANCHiETOTHRipiD^, mihi. 



Ceratothrips, Reuter, chiefly on account of the 6-jointed antennas, 

 which possess only a single-jointed style, the reduction in the antennal 

 joints not being caused by fusion. Ceratothripidje, mihi. 



TUBTJLIFERA, 



Ecacanthothrijjs, Bagnall (Phlceothripid2e), chiefly on account of the 

 specialized antennal sense-cones congregated (in the form of numerous 

 fingers) on the third antennal joint. Ecacanthothripid^, mihi. 



XXVI. — Entomological Notes from the London School of 

 Tropical Medicine. — No. IV. Bloodsucking Diptera from 

 Port Darwin, Australia. By SoPHiA L. M. SUMMERS, 

 M.A., B.Sc, Carnegie Student of Aberdeen University. 



Dr. C. L. Strangman has recently presented to the School 

 a collection of blood-sucking flies collected by himself in 

 Port Darwin and its neighbourhood, in the northern territory 

 of the Government of South Australia. It includes eighteen 

 species, and as very little seems to be known of the blood- 

 sucking Diptera of this part of the world, it seems advisable 

 in describing several of the new forms to put the names of 

 all the species on record. All the identifications have been 

 confirmed from the collections in the British Museum 

 (Natural History) and may therefore be regarded as 

 authentic. 



I take this opportunity of renewing my acknowledgments 

 to Messrs. E. E. Austen and F. W. Edwards for their 

 kindness in giving me access to the collections in their 

 charge.
