EATON— DIPTERA, PSYCHODID^ 429 



5. Psychoda solitaria, sp. nov. ? (PI. 26, fig. 6 a — d). 



This is one of some doubtful species related closely to Psychoda albipennis Zett. 

 in colour and structure (if indeed distinct) having ovate vplngs pointed at the end of R\ 

 an ill-defined anterior basal cell, the sectorial fork sometimes incomplete, the 1st joint in 

 the antenna shorter than the next two combined, the 3rd joint equal in length to the 

 4th and like most of the joints in the flagellum lageniform with a rounded or napiform 

 base and a subfiliform neck. Gonopods geniculate ; protopodite subequal in length to the 

 exopodite. 



In Psychoda albipennis (PI. 26, fig. 7 a — d), joint no. 13 in the antenna is followed 

 by two diminutive rudimentary joints; no. 14 visible only under a high power, is 

 colourless, narrow and small; no. 15, sub-globular or ovoid and dark. Length of wing 

 0-9 to 1-8 ram. 



Loc. Europe fi-om Scandinavia to the Basses Pyrenees. Prep., Eaton, no. 7G. 



Psychoda solitaria (PI. 26, fig. 6 a — d) appears to differ in having joint no. 14 of 

 the antenna also sessile but terminal, and subglobular with an apiculus. The question 

 of identification arises in connection with the possibility of this appearance being mis- 

 leading. Length of wing 1"15 mm. 



Loc. Seychelles. Mahe : Cascade Estate, about 800 feet, 33 specimens (carded). 

 Prep., Eaton, no. 76 a. 



Philosepedon, Eaton (1904). 



Differs from Psychoda in having no bristling hair on R^ ; obtuse external $ 

 genitalia, and the ovipositor being not rostrate. Appendages of $ inferior genitalia 

 few tenaculate. 



6. Philosepedon humeralis (Hoffmann) ; Meig. 

 A single % fly agrees with the European insect. 



Loc. Seychelles. Mahe : Cascade Estate, about 800 feet. 



7. Philosepedon triungidatus, sp. nov. 



Four flies, carded similarly to the preceding, and obtained at the same locality, differ 

 from it in being darker in the wing-membrane (the hair is largely destroyed) ; and the $ 

 apparently has 3-tenaculate (not 2-tenaculate) inferior genital appendages ; the tenacula3 

 equal and divergent, otherwise similar to the corresponding parts in Philnsepedo7i 

 humeralis, so far as can be seen. 



Loc. Seychelles. Mahe : Cascade Estate, about 800 feet. 



Telmatoscopus, Eaton (1904). 



As constituted hitherto, there are 14 species sub inan4 ranked in this genus, 12 of 

 which have been described ; but of some only one of the sexes is known. The terminal 

 joint in the $ 16-jointed antenna is not relatively diminutive in comparison with its 

 predecessors, and the 3rd joint equals the 4th in length. Wings ovate-lanceolate ; 

 pedicel of the sectorial fork inserted in or at the anterior basal cell. Texiacular spinules 

 of the inferior genital appendages of $ numerous.
