Bym^noplera from the Khasia Bills. ol5 



Head thickly covered with white pubescence below the 

 antenna ; the face and, to a less extent, the clypeus punc- 

 tured ; the front closely, finely, transversely striated in the 

 middle, its sides sparsely punctured. The median segment 

 is more closely and strongly punctured than the mesopleurae, 

 the areola is irregulai'ly reticulated, most strongly on the 

 apex ; the apical slope is irregularly striated, the striae 

 running into reticulations on the sides. Postpetiole ob- 

 scurely, finely, longiludinally striated in the middle ; the 

 second and third segments are closely and distinctly punctured 

 in the middle; the gastrocoeli are stoutly striated at the base. 



This is a smaller species than the tvpe of the genus 

 (C. nigrijes, Ann. & Mag. Xat. Hist., Feb. 1902, p. 152), 

 and may be easily separated from it by the rufous legs. 



Algathia * albitarsis, sp. n. 



Black ; the face, clypeus, a band on the middle of the 

 upper inner orbits (narrowed obliquely on the lower half), 

 an oval mark on the lower edge of the outer orbits, the edge 

 of the pronotum behind, the scutellum, except at the base, 

 the postscutellum, two large marks on the sides of the apex 

 of the median segment, covering the spines above, the base 

 of the pronotum, a small mark on the apex of the propleurje 

 behind, and the tubercles, white ; the apex of the first abdo- 

 minal segment, the base of the second, its apex more broadly, 

 and the apex of the third segment, yellow, tinged with fulvous ; 

 the apical two segments clear pale yellow. The four front 

 coxae and trochanters are white, the rest of the legs fulvous, 

 except the apices of the tarsi, which are black ; the hinder 

 legs rufous, their coxae black, broadly white above and dull 

 rufous at the base below ; the trochanters on the outer side, 

 the apex of the femora, of the tibiae, and the basal joint of 

 the tarsi, black ; the rest of the tarsi white. Wings hyaline, 

 the stigma and nervures black. Antennae black, the scape 

 beneath and a band in the middle white. ^ •

Black ; the face, clypeus, mandibles, the inner eye-orbits to 

 the lower ocellus, a mark, longer than broad, behind the 

 posterior, the outer orbits on the lower two thirds (narrow 

 above, broad below), the malar space, the tegulte, a naiTow 

 line on the pronotum, a broader one on the lower edge of
