on apical half. Middle tibia with long villosity from before mid- 

 dle, and one bristle on outer front side. 



Genitalia (fig. IG) large; forceps black, large, strongly curved, 

 with dense retrorse, short hair behind, a few more bristly near tip, 

 which is suddenly reduced to a small curved thorn; penis red, long, 

 with a large apical hook directed forward. I have not seen this 

 species before ; it will be easily recognized from the genitalia. 



Sarcophaga ochripyga^ p. 285. 



Two males, four females. A male from Frontera and a female 

 from Tepetlapa were set apart by Doctor Townsend on his recent 

 visit and both labeled " Oxysarcodexia oitusifrons Thomson." This 

 species was described from two females, locality Galapagos Islands^ 

 and is with little doubt the same as Sarcophaga taitevsis Schiner, 

 the latter having priority as generally considered of one year. 

 Schiner's species has not as yet been definitel}?^ identified from other 

 regions than the islands of the Pacific, hence I doubt Townsend's 

 identification. I therefore restrict the species to the other male, of 

 which my austi'cdis is a sjmonym.^" 



Sarcophaga aequata, p. 286. 



Two males of two species. I exclude the one from Teapa, which 

 is nearly related to aiiioena Aldrich, and restrict the species to the 

 one from Amula, which is a species new to me. 



Male. — Hind tibia with four or five short, slender villous hairs,, 

 hardly could be called villous at all; genital segments red; dorso- 

 central four (or five). Head light golden pollinose; front narrow 

 above; antennae and palpi black; mesonotum with three distinct 

 black stripes and four golden ones; abdomen golden on sides, tessel- 

 lated; second abdominal segment without median marginals, third 

 with a pair. Middle tibia with one bristle on outer front side. 

 Acrostichal hairlike, but a little coarse. Genitalia as in Figure 17. 

 The peculiar forceps should be instantly recognizable; they are 

 black and have three spines as shown. The accessory plate (outer 

 forceps) is black apically, while the penis is yellow dorsally, brown 

 ventrally. 

 Sarcophaga a^.cta, p. 286. 



Nine males, one female. Apparently all the same species. Another 

 male, from Rio Paragai, Guerrero, and not listed by Van der Wulp^ 

 has a type label, but is a different species. I disregard this speci- 

 men. The species belongs to the Oxysarcodexia group, with genitalic 

 characters different from all known to me. The fifth sternite pro- 

 duced in two long, slender, parallel arms, about as in timida but 

 more slender. The forceps viewed from behind are wide and con-
