dorsal and 2 stout, dorsal bristles at the middle; one 

 of these elements at the apical third is matched antero- 

 dorsally, posteroventrally, and anteroventrally by a 

 similar, long, stout bristle. There is an additional, 

 stout, ventral bristle immediately beyond the first. Aii- 

 terior femur with 1 anteroapical bristle and a rather 

 copious, ventral fringe of long, stiff hair; its tibia has 

 1 anterodorsal at the base, 2 dorsal from the middle, 1 

 very stout posterior bristle at the outer fifth, and a long, 

 posteroventral fringe of stiff, bristly hairs ; apical cir- 

 clet of 8 bristles. Basitarsus short and robust and both 

 its anterior and posterior apical bristles long and stout. 

 Anterior coxa with a dense patch of weak, long bristles 

 and bristly pile anteriorly, the lateral surface concave ; 

 middle coxa with 10 or more bristles laterally and 2 

 posteriorly; posterior coxa with 2 bristles laterally, 2 

 anteriorly. Tarsi end in long, spatulate pulvilli, quite 

 stout, long empodiiun, and long, sharp claws, strongly 

 bent at apex. 



Wings: The wings are hyaline or tinged and com- 

 paratively slender; subcostal cell quite narrow. Mar- 

 ginal cell wide, narrowly closed with very short stalk, 

 the end somewhat bulbous. First submarginal cell 

 slightly narrowed in the middle; the anterior branch 

 of the third vem ends above the wing apex. Three 

 submarginal cells are present. A crossvein is present 

 basally between the anterior and posterior branches of 

 the third vein. The posterior branch of the third vein 

 ends far behind the wing apex. First posterior cell 

 very long and narrow and of uniform width ; both end 

 veins of the discal cell of nearly equal length. Fourth 

 posterior cell closed and stalked, convex anteriorly and 

 distally; second basal cell ends in 2 veins; anal cell 

 closed; alula large, ambient vein complete. Wings 

 strongly rippled. 



Abdomen: The abdomen is unusually slender and 

 gently tapered from the base, subcylindrical and dis- 

 tinctly longer than the wings. The tergites laterally 

 are strongly swollen and convex. Pile fine, appressed 

 and setate but moderately long and erect on the sides 

 of the first three tergites. Distinct, stout, tergal bristles 

 are present ; 2 or 3 on the first tergite and 1 or 2 sub- 

 postmarginally and laterally on tergites 2 to 6 only. 

 Sternites with fine, more or less appressed pile and no 

 bristles. Eight tergites present in the male, the last 

 three a little shortened. There are seven tergites in the 

 female, those beyond are incorporated in the ovipositor. 

 Male terminalia large, moderately elongate, clublike. 

 The proctiger lies flat or is concealed. The exposed part 

 of the gonopod is extremely small and short and is 

 largely ventral and basal in position. Hypandrium 

 quite short. Eight stemite unmodified. The very 

 large, laterally convex superior forceps tend to enclose 

 the cavity both above and below. In the females the 

 eighth segment is long and cylindrical and a little nai-- 

 rowed posteriorly. The ninth and tenth segments are 

 also cylindrical and more narrowed so that the whole 

 ovipositor resembles a long, slender cone. Tenth seg- 



ment with very short, erect, dorsal spines and apex with 

 a pair of longer, stout spines. The ovipositor is rather 

 similar to Apoclea. 

 I give below a translation of Bigot's description : 



Type of genus: Teretromyia cothurnata Bigot, 1859, by mono- 

 typy. 



Antennae with style elongate, obtuse at apex, the third seg- 

 ment ovoid, bases close together and inserted on the front. 

 Face; two swellings added, a little protruding, the mystax 

 reaching the base of the antenna. Vertex very concave. Abdo- 

 men ; narrow, rather short ; female, ovipositor almost as long as 

 the abdomen and formed of three segments, .ilmost equal be- 

 tween them, compressed and drawn out and tapering at the end. 

 Wings; marginal cell closed almost at the border; transverse 

 veins situated on different lines (not aligned?), three sub- 

 marginal cells, four posterior cells [quatre poaterienres'i, first 

 rather large and largely open, second narrow, and a little longer 

 than the following, third very widely open, fourth and anal cells 

 closed, appendiculate, the following (anal lobe?) widely open. 

 Tarsi ; basal segment a little shorter than the next two com- 

 bined. Claws sharp. Male terminalia upright, without a spiny 

 or thorny crown [epiceuse'i. Relative of Eichoichemus Bigot, 

 1857, p. 543.

I have not seen the species Philodicus cothurnata 

 Bigot from Madagascar, the type of Bigot's genus 

 Teretromyia, but Dr. Hobby of the Hope Department 

 of Entomology, University Museima, Oxford, England, 

 wrote me in 1952 : "Bigot's cothurnata, the type of the 

 genus Teretromyia Bigot is in Bigot's carton no. 4 

 under the genus Philodicus to which it had been as- 

 signed by Bigot apparently subsequently to its inclu- 

 sion in the genus Teretromyia.'''' 



In this genus I have given the arrangement of species 

 largely as found in Kertesz (1909). See Ricardo 

 (1921) for numerous changes in assignment and syno- 

 nymy of species which she has suggested in both Philo- 

 dicus Loew and Alcimus Loew.
