bluntly recurved and bearing many short, fine, backwardly directed 

 hairs, the whole forming a very striking modification, which, together 

 with the curiously modified subgenital plate with its pecuHar ter- 

 mination, will serve to readily differentiate the male of this species 

 from its described allies. 



Legs strongly spined ; anterior femora armed beneath on the ante- 

 rior margin with a dozen stout spines occupying about the apical four- 

 fifths of the entire length, the apical one long, the next one-half as 

 long, the next three still a third shorter, and the rest successively 

 longer and stouter till those at the base are fully as long as and 

 shghtly stouter than the apical one; the opposite margin bears four 

 or five large spines; posterior legs absent; arolia present but rather 

 small. 



Measurements. — Length, pronotum, 3 mm. ; tegmina, 10 mm. ; width, 

 head, 2.25 mm.; prontum, 3.25 mm.; tegmina, 3 mm.

BLATELLA, species 



One male, Buitenzorg, March. 



This is apparently not any one of the species of the genus recorded 

 from Java. Like B. hemtti Shelford, it resembles superficially an 

 Ischnoptera. 



MARGATTEA ANCEPS Krauss 



Blatta {Phyllodiomia) anceps Krauss, Semon's Zool. Forsch. Austral. & Malay 

 Archipel., vol. 6, 1903, p. 749. 



Two females, Tjibodas, Mount Gede (7,000 feet altitude); one 

 female. Mount Salak, April 5. 



This species was described in the genus Blatta, subgenus Phyllodro- 

 mia, later referred to Allada by Kirby, and still later listed in Phyl- 

 lodromia by Shelford. Its real position, as shown by the present 

 specimen, is in the genus Margattea of Shelford. 



MARGATTEA BUITENZORGENSIS, new species 



Description, male {female unlcnown). — General color uniforml}'' pale 

 yellowish. Head narrow, projecting considerably from beneath the 

 pronotal disk; eyes somewhat darker than the general color and 

 rather widely separated, connected on the vertex by a broad red- 

 dish-brown band; antennae yellowish, the basal segment with a 

 fuscous spot beneath; palpi same color, the terminal segment flat- 

 tened and infuscated beneath.
