The typical (and onh') species is atripalpis, Bezzi, Bull. So. 

 Ent. Ital., xxvii, 60 (1895) {Hmnatohia), described from Italy. 



Austen's recently erected genus Bdcllolarynx is very closely 

 allied. 



BDELLOLARYNX, Austen, 1909. 



Ann. Mag. Nat. Hist. (8), iii, 290. 



"Small, stouth' built, thick-set flies, closely allied to 

 Hceinatohia, R. D,, but distinguishable as follows : — No sexual colour- 

 dimorphism (unless it be in wings) ; front, facial angles, and 

 anterior margin of buccal cavity less prominent ; jowls descending 

 considerably behind, instead of nearly horizontal, but basi- 

 occipital region much less protuberant ; bristles below facial angles 

 small and fine, instead of relatively coarse ; in cf front wider 

 with upper inner margins of eyes more nearly parallel, less ap- 

 proximate in middle of front ; arista feathered above with consider- 

 abh' longer hairs, and below with about six fairly long hairs ; ist 

 and 3rd longitudinal veins entirely bare, without bristles at base." 

 The chgetotax}^ is as follows : Humeral bristles 2 ; post-humeral 

 I ; notopleural 2 ; prsesutural i ; supra-alar i ; intra-alar i ; post- 

 alar 2 ; dorso-central 5 (2 in front of and 3 behind suture, ma^' be 

 difficult to distinguish, especialh^ in 9 ) ; inner dorso-central i (some- 

 times 2 in cf ) ; scutellar 4 (i prsebasal, i basal, i discal, situated 

 close to lateral margin, i apical) ; mesopleural about 10 or 12 ; 

 sternopleural i : i. 



" Bdellolarynx is distinguished from H cematohosca , Bezzi, 

 by the palpi being much more spatulate at the tips, by the arista 

 having a greater number of hairs below, and, in the wing, b}^ the 

 shape of the ist posterior cell and the course of the terminal portion 

 of the 4th longitudinal vein (in H cBmatohosca the latter details are 

 the same as in Stygeromyia , Aust.). Typical species, B.sanguino- 

 Iciitus, sp. nov.' '

 cf $ . India, Ceylon, Assam. Long. & 4I-5 mm. ; 9 zh^l ii^"i- 

 ' ' Mouse-grey or slate-grey, clothed with short black hair, 

 bristles also black ; palpi buff ; dorsum of thorax with a pair of 

 extremely narrow, wideh' separated, parallel, longitudinal ad- 

 median blackish stripes, a somewhat triangular blackish mark 

 extending backwards from inner end of each humeral callus, and 

 an elongate blackish streak in a line with latter mark behind 

 transverse suture (two outer marks less distinct in 9 ) ; dorsum of 

 abdomen with a narrow, interrupted, longitudinal, median, clove- 

 brown stripe, and, on 2nd and 3rd segments, paired transverse, 

 roughly triangular, clove-brown blotches, the pair on 2nd segment 

 especiall}^ large. Wings hyaline or tinged with tawny olive m& ,
