Three New Sub-tropical Gall Midges (Itonididae, 



Dipt.). 



By E. P. FELT, State Entomologist, Albany, Xew York. 



The gall midge fauna of the warmer parts of the earth is 

 comparatively unknown and it is, therefore, with more than 

 usual interest that we record the characters of several new 



species. 



ALEXOMYIA n. g. 



This Porricondylid genus is easily recognized by the short, 

 distinct cross vein forming a well marked angle with cost a. 

 the forked fifth vein not close to the posterior wing margin, the 

 supernumerary vein at the base of subcosta extending almost 

 to the cross vein, the simple claws and the rudimentary pulvilli. 

 It is easily separated from the related and possibly associated 

 Argentine Liebcliola Kieff. & Jorg. by the uniarticulate palpi 

 and the short spine-tipped ovipositor. Type: A. cilia ta n. sp. 



Alexomyia ciliata n. sp. 



The species described below was received under date of 

 September 22, 1919, from Professor C. P. Alexander, Urbana. 

 Illinois. It was collected at Praia, State of Para, Brazil, and 

 labeled 6-7-19. The type (Cecid. 1805) is deposited in tin- 

 New York State Museum and is unusually interesting becau>v 

 of its close relationship to a striking Argentine species. 



$ . Length, 4.5 mm. Antennae nearly as long as the body, sparsely 

 haired, black or nearly so, probably with 14 and possibly with 16 seg- 

 1 merits, the first obconic, the second with a length about half its diame- 

 ter, the 3rd and 4th fused, the 5th with a stem one-third the length 

 of the cylindrical basal enlargement, which latter has a length about 

 four times its diameter, a sparse whorl of stout setae basal ly and a scat- 

 tering whorl of long setae subapically. Circumfila at the basal fourtli 

 and apically are connected with irregular longitudinal moderately high 

 and heavy fila. Terminal segment missing. Palpi uniarticulate, the 

 segment broadly oval and with a thick group of rather short, stout 

 sensory spines apically. 



Mesonotum shining dark brown, the submedian lines thickly haired. 

 Scutellum and postscutellum dark yellowish brown. Abdomen dark 

 reddish brown. 



Wings hyaline with a length fully three times the width, msta dark 

 brown, the supernumerary vein extending nearly to tlx cross vein, 

 subcosta uniting with the margin near the basal half, the cross vein 

 short, well-developed, at a distinct angle with costa, the third vein
