PHYTOPHAGOUS AND PARASITIC HYMENOPTERA. 97 



I only know the 6 of this genus. It comes near to OspryncJio- 

 tus^ which may be known from it by the rostriform head, with 

 long malar space, and by the disco-cubital nervure not being 

 broken by a stump of a nervure. In The Entomologist, 1903, 182, 1 

 described an Osjnynchotus 2}eronatus from India. I was not then 

 acquainted with the type of Osiwynchotus from the Cape, Now 

 that I have seen it, I find that my Indian species is a Linnoceras, 

 Ta.sch..= Osprynchotus Schmied. no7i Spin.(Ent. Nachr. XVI., 85). 

 Linnoceras may be known from the genus here described by the 

 transverse median nervure in hind wings being broken at, not 

 below, the middle, by the more elongate clypeus, not separated 

 from the face, large projecting labrum, longer, more slender, 

 mandibles, of which the upper tooth is much the longer. In 

 Bathijcrisis the mandibles are short, thick, with two short stout 

 teeth of equal length. In Dr. Ashmead's tables, Bull. U. S. Nat. 

 Mus. XXIII., 40, OsiJryiicliotus is placed in the division with the 

 transverse median nervure in hind wings "broken distinctly below 

 the middle, usually /^r below the middle," whereas it is broken 

 shortly above the middle. 



36. — Bathycrisis striaticollis. sp. nov. 



Black, the inner orbits, broadly below, narrowly above, a nar- 

 row line in the centre of the outer, a mark, longer than broad, 

 transverse at the apex and interrupted in the middle above by a 

 fovea, a mark in the centre of the clypeus, mandibles, except at 

 the apex, a small mark on either side of the pronotum, a smaller 

 one in front of the tegulae and tubercles, lemon-yellow ; legs, with 

 the greater part of the femora, the tibiae and the tarsi, except at 

 the apex, rufo-testaceous ; the coxae and femora marked below 

 with yellow. Wings hyaline, the nervures and stigma black, 6. 



Length 9 mm. 



Trincomalee, Col. Yerbury. 



Head covered with long white hair. Face closely punctured, 

 the clypeus smooth, the lower part smooth and shining ; the part 

 immediately below the ocelli strongly transversely striated, and 

 the striae curved. 



The vertex behind the ocelli closely punctured ; the occiput 

 margined, the temples wide, obliquely narrowed. Pronotum 

 strongly irregularly striated. Mesonotum closely punctured ; in 

 the depressed centre the punctuation is closer and runs into 

 reticulations. The scutellum is less closely punctured and more 

 shining than the mesonotum. Metanotum closely rugosely 

 reticulated. Pleurae closely strongly punctured.
