equal to the width of the pronotum. Legs dull luteous, more or less 

 obscured with fuscous, especially just before the tip of the femora. 

 Abdomen very dark mahogany brown, the lateral plications of second 

 and third segments very prominent, forming blunt conical tubercles; 

 surface of abdomen nearly smooth ; last dorsal segment in both sexes 

 with a minute circular central depression. Forceps of male nearly 

 three-quarters as long as the abdomen, flattened beneath, directed at 

 first, for a short distance, horizontally and slightly outward, then, at 

 a superior constriction, bent slightly upward and slightly inward to 

 the incurved tip, which by a sudden constriction at its base resembles 

 a claw; the lower inner edge of the upturned portion is distantly 

 and very delicately denticulate, and the middle of the upper surface 

 bears a large, laminate, compressed, triangular pointed tooth ; forceps 

 of female simple, slender, approximated at the base, and beyond 

 attingent and straight to the finely pointed incurved tip ; they are 

 nearly horizontal but regularly curved, first downward and then 

 upward, minutely denticulate along inner edge. Length of body, 

 9 mm. ; of antennae, 7 mm. ; of wings and tegmina, 3.5 mm. ; of hind 

 femora, 2.5 mm.; of forceps, 3.5 mm. 3 d", 4 ?. Brazil. 



49. Forficula hirsuta. Head dark mahogany brown, the 

 front tumid, with a pair of short longitudinal furrows dividing the 

 space between the antennae ; palpi dull luteous ; antennae (broken 

 beyond fifth joint) uniformly dark mahogany brown. Pronotum 

 as in F. variicornis, but uniformly reddish black, the sides slightly 

 elevated. Tegmina dark reddish brown, twice as long as the 

 pronotum, squarely docked at tip ; wings of same color, scarcely 

 tipped with dirty luteous. Femora uniform dark reddish brown ; 

 rest of legs dull luteous. Abdomen dark reddish brown, the poste- 

 rior edges of the segments blackish, the lateral plications of the sec- 

 ond and third segments prominent, the surface profusely, minutely 

 and transversely punctato-striate with abbreviated striae, the last 

 segment with a short median longitudinal impression. Head, an- 

 tennae, prothorax, base and lower edge of tegmina, exposed part of 

 wings, legs and abdomen rather sparsely covered with moderately 

 long pile. Forceps nearly as long as the abdomen, very slender, 

 cylindrical, approximated at base, beyond attingent, straight to the 

 incurved pointed tip. Length of body, 9.75 mm. ; of tegmina and 

 wings, 4.5 mm.; of hind femora, 2.9 mm.; of forceps, 4 mm. 1 ?.
