Ootctrasficlius, sp. no v. 



Head strongly transverse, fully as wide as, or wider than, the 

 thorax, where this is widest, the ocelli in a slightly curved line 

 (or extremely wide triangle) the posterior being very much 

 more distant from one another than is either from the anterior. 

 Antennae with seven distinct joints and 'a ring-joint, which un- 

 der high powers of the microscope appears composite, as if 

 compounded of two or three fused joints; the scape slender and 

 long, the pedicel elongate, the first funicle joint very long, nar- 

 rowed on its apical part, the two next funicle joints shorter than 

 the first, but elongate; the next joint is shorter and wider and, in 

 some aspects at least, appears to belong to the club, as its apex is 

 closely apphed to the base of the apical antennal joint; the latter 

 is without any distinct divisions, and is probably the true club, 

 Mesonotum without a grooved line; the scutellum with four, 

 two dorsal and parallel, each placed just within the setigerous 

 tubercles, the other two lateral. Wings evenly hairy, marginal 

 vein fully as long or rather longer than the submarginal, and 

 three or four times as long as the stigmal, the apical fringe 

 longis'h and continued round the costa to the marginal vein, and 

 on the opposite margin half-way to the b'ase. Abdomen longer 

 than the head and thorax, depressed above, acuminate, the ovi- 

 positor slightly exserted.

Ootctrastichns bcatiis, sp. nov. 



Pale yellow or greenish yellow with the following parts dark 

 fuscous or black: Two subcontiguous spots on the mesonotum 

 in front, extending on to the pronotum and there connected. 

 One at each posterior iiind angle of the pronotum. The anterior 

 angles of the parapsides and of the anteriorly-produced axillae, 

 a line and one or two obscure marks near the tegulae ; four 

 microscopic setigerous dots on the scutellum, one pair of which 

 are before the middle, the other pair at the hind margin; propo- 

 deum towards the sides, four or five pair of lateral dorsal spots 

 on the abdomen (a pair to a segment), the ovipositor and the 

 tip of the tarsi. In certain lights these dark spots show metallic 

 green reflections. Thorax above with very fine microscopic 

 longitudinal rugulosity; basal abdominal segments with two or 

 three setigerous dots on each side, the apical ones with a com- 

 plete transverse row. A long sinuate seta on eac'h side of the 

 abdomen near the tip, which is sparely pilose. The markings
