short, the tips projecting far beyond the very simple chitinized, pleural appen- 

 dages which are situated on the inner face; these appendages are two in number, 

 one appearing as a slender, cylindrical, chitinized arm, the other appendage 

 appears as a flattened plate which runs out into a small, chitinized point. From 

 the hypopygium projects a long, slender rod, pale, the tip enlarged and slightly 

 blackened. The homologies of this rod cannot be told from the material at 

 hand. 



Habitat. — Guatemala. 



Holotype. — d^, Gualan, January 13, 1905, (J. S. Hine). 



Allotype. — 9. 



The types were taken from the mouth of a female damsel-fly {Helcerina 

 tricolor Burm.) Ijy Dr. C. H. Kennedy. By the writer's key to the American 

 species of Teucholahis (Trans. Amer. Ent. Soc, \^ol. 40, pp. 235-239: 1914), 

 Teucholabis pahulatoria will run to T. jocosa Alexander from which it is readily 

 told by its small size, the very different coloration of the thorax, and the \'enation. 



Erioptera (Mesocyphona) cladophora, sp. n. 



Generally similar to E. anntilipes Williston; tibia^ with four brown bands; 

 2nd Anal vein strongly sinuous and with a spur before its tip. 

 Male. — Length 2.8 mm.; wing 2.8 mm. 

 Female. — Length 3.5 mm.; wing 3.5-3.6 mm. 

 Generally similar to E. anniilipes, differing as follows: 



Most of the femora with four brown bands; tibiae with four narrow brown 

 bands, alternating with four subequal white areas; metatarsi with the base and 

 apex dark brown; tarsal segments three to five and the end of the second dark 

 brown. Wings with a faint brownish tinge; large whitish subhyaline areas 

 occupy the ends of all the cells along the wing-margin; similar white areas in 

 the ends of cells R and M and before the large spur of the 2nd Anal \'ein in cell 

 Lst A; small brown spots at the ends of all the longitudinal veins; a narrow, 

 dark brown seam along the cord; veins dark brown. \'enation: Generally as 

 in E. annulipes but the 2nd Anal vein is very remarkably distinct; very strongly 

 bisinuous, almost as in the genera Helobia and Symplectomorpha, before the last 

 curve with a strong spur that juts into cell 1st A, this spur directed cephalad 

 and basad, in some specimens almost attaining vein 1st A and thus appearing 

 as a supernumerary cross-vein in cell 1st A (as in the genus Discobola) ; this spur 

 is surrounded by a dark seam. Male hypopygium with two long, slender 

 pleural appendages, the outermost bifid almost to the base and thus appearing 

 as two separate appendages; inner appendage longest and more strongh- cur\ed 

 than in the others; gonapophyses appearing as a long, slender, slightly-incurved 

 rod with the apex blackened. ^.
