1876.] 259 [Scudder. 



dorsal segment with a broad median depression, and the hinder edge 

 scarcely produced angularly over each of the arms of the forceps. 

 Forceps flattened triquetral, moderately stout, as long as the teg- 

 mina, straight nearly to the tip, then rather sharply incurved to a 

 bluntly pointed tip; inner double edge irregularly but rather fre- 

 quently toothed, larger at base than beyond, but furnished with a not 

 very conspicuous broad triangular laminate tooth just beyond the 

 middle. Length of body, 18.5 mm.; of antenna?, 15 mm.; of teg- 

 mina and folded wings, 7.75 mm.; of hind femora, 4 mm.; of forceps, 

 6.25 mm. 1 ?. Chontales, Nicaragua. 



This species differs distinctly from T. hrasiliensis and T. Saussurei 

 in having longer forceps and nearly uniformly dark wings, of the 

 color of the tegmina. 



53. Spongophora forfex. Dark castaneous brown, the 

 mouth parts scarcely paler, the antennae castaneous, becoming infus- 

 cated beyond the base. Legs luteo-castaneous, the front of the 

 femora blackish fuscous; exposed part of wings pale mahogany brown; 

 tip of the tegmina obliquely docked, slightly and roundly excised, 

 and next the inner edge strongly produced; posterior edge of the 

 abdominal segments with a series of closely crowded minute notches; 

 terminal segment rugulose, with granulations, which are absent from 

 the two stripes down the middle, grow larger and more abundant 

 posteriorly, and bead the posterior edge. Forceps reddish, nearly as 

 long as the body, depressed cylindrical, very slender, nearly straight, 

 slightly incurved on the basal half, beyond straight and then incurved 

 at the tip, the extremity of whieh is pointed; the inner edge is 

 slightly rugulose, and just before the middle has a slight tooth. 

 Length of body, 22 mm. ; of tegmina and wings, 9.5 mm. ; of hind 

 femora, 4.25 mm.; of forceps, 19 mm. 1 6 from the collection of 

 Dr. Schaum; the locality is unknown, but is doubtless some part of 

 tropical or subtropical America. It belongs to the group of S. par- 

 allela (Westw.) and S. prolixa (Psalid. parallela Dohrn nee Westw.), 

 but differs from them in coloration, and in the structure of the forceps. 



54. Ancistrogaster gulosa. Head very dark castaneous 

 brown with very thin short pile on the occiput; antenna? 12-jointed, 

 pale brown, the basal joint darker; palpi pale brown. Pronotum 

 dark brown, the sides dull luteous, slightly broader than long (cf), or 

 of equal length and breadth (?), the sides slightly convex, slightly 

 narrowing posteriorly, the posterior margin well rounded; broadly 

 depressed just behind the centre with a faintly impressed median line
