rent nervure is received beyond the middle of the cellule, and 

 the area on the base of metanotum is almost of equal width 

 throughout. 



Mutilla devia, sp. nov. 

 Black ; the head, thorax (the pronotum and the mesopleurae 

 densely), the apices of the abdominal segments and the legs covered 

 with longish white pubescence ; the wings hyaline, the nervures 

 black ; the first abscissa of the radius straight, sharply oblique, about 

 one-fourth shorter than the following two united, the second about 

 one-fourth longer than the third ; the first recurrent nervure is 

 received in the middle of the cellule. Tegulae dark testaceous at the 

 base, the apex white ; they are covered with white pubescence. Keel 

 on basal ventral abdominal segment distinctly dilated at the apex. <? . 

 Length, 7 mm. 



Kuching, Borneo (John Hewitt, B.A.). 



Vertex on either side of the ocellar region finely, closely, longi- 

 tudinally striated, sparsely covered with longish black hair; the front 

 densely covered with silvery pubescence. Pronotum closely, the 

 mesonotum less closely, but more strongly punctured ; there are two 

 distinct furrows near the centre of the apical half of the mesonotum. 

 Scutellum more closely, rugosely punctured than the mesonotum. 

 The space bordering the scutellums and the base of the metanotum 

 densely covered with depressed silvery pubescence. There is no 

 clearly defined area on the base of the metanotum unless it is hidden 

 by the dense pubescence ; the metanotum is rather coarsely reticu- 

 lated. Calcaria white. Third antennal joint about one-quarter 

 longer than the fourth.

By T. D. a. Cockerell. 



Tetralonia argyrophila, sp. nov. 

 <y . Length about 13J mm., black, with the hair on the head, 

 thorax, and basal segment of abdomen (covering the latter densely) 

 ochreous, rather bright on the thorax above. Clypeus bright lemon- 

 yellow, the yellow angularly incised laterally ; labrum cream-colour 

 with a narrow black edge; mandibles without any yellow spot; 

 antennae very long, entirely black ; third joint very short, its shorter 

 (anterior side) about as long as its apical breadth antero-posteriorly ; 

 mesothorax dull, densely punctured ; area of metathorax rugose ; legs 

 with pale hair, that on inner side of basitarsi light orange ; middle 

 tarsi not distorted ; hind spur of hind tibiae normal ; abdomen beyond 

 the first segment shining black with sparse black hair, but with scat- 

 tered long silvery-white hairs, becoming numerous toward the apex, 

 and forming a sort of thin fringe on the sides of segments four to six ; 

 apical margin of sixth and sides of seventh with short light hair. In 

 my table in Trans. Amer. Ent. Soc. 1906, this runs to 4 on p. 79, and 

 does not precisely fall in either category there indicated. On the whole
