Mr. F. Walker on some new species of Chalcidites. Ill 



of the oviduct as long as the body : legs yellow ; coxae and thighs 

 green ; tips of the latter yellow ; tips of the tarsi fuscous : wings 

 limpid ; nervures piceous ; ulna shorter than the humerus ; radius 

 very short ; cubitus extremely short. The characters which are 

 common to the genus, such as the minute transverse undulations on 

 the thorax, the long scutum, the distinct sutures of the parapsides 

 and the extremely short podeon, are here omitted. The length of 

 the oviduct will distinguish this insect from most of the British spe- 

 cies of Callimome *. In this character it most resembles C. Bedeguaris, 

 varians, scutellaris, Hedera and Arundinis, but it has more slender 

 antennae and a smaller body than any of these species. 

 October ; near London. 



6. Lamprotatus Rubrius, mas. Viridis, ahdomine CBneo-viridi, anten- 

 nis nigris, pedibusfulvis, femoribus viridibus, alls limpidis. (Corp. 

 long, lin. 1 J ; alar, lin 2 J.) 



Male. — Body convex : head and thorax finely squameous : head a 

 little broader than the thorax : antennae stout, filiform, not longer 

 than the thorax ; first joint long, dilated beneath ; second short-cya- 

 thiform ; third and fourth very minute ; fifth and following joints 

 to the tenth long, linear, successively decreasing in length ; club 

 linear, conical at the tip, twice the length of the tenth joint : thorax 

 oval, stout, deep, very convex : prothorax moderate, transverse : 

 scutum of the mesothorax broad ; sutures of the parapsides very di- 

 stinct, approaching each other ; axillae large, triangular, not conni- 

 ving; scutellum truncate-conical, not impressed in front but having 

 a transverse channel near the tip : metathorax large, obconic, decum- 

 bent : podeon short, stout, punctured, less than one-sixth of the 

 length of the abdomen : abdomen oval, smooth, shining, slightly con- 

 vex, shorter and much narrower than the thorax ; metapodeon occu- 

 pying more than one- third of the dorsum, having a broad channel 

 throughout its length ; octoon less than one-half of the metapodeon 

 in length ; ennaton much shorter than the octoon ; decaton a little 

 longer than the ennaton ; protelum as long as the ennaton ; para- 

 telum shorter than the protelum ; telum very short : wings ample ; 

 humerus much less than half the length of the wing ; ulna not more 

 than half the length of the humerus ; radius twice the length of the 

 ulna ; cubitus rather shorter than the ulna ; stigma large, pyriform, 

 emitting a short branch towards the radius. 



Found by Dr. Greville near Edinburgh. 



7. Lamprotatus Helenor, mas. jEneo -viridis, antennis nigris, pe- 

 dibusfulvis, alis limpidis. (Corp. long. lin. 1^; alar. lin. 21.) 



Female. — Body convex : head and thorax finely squameous : head 

 a little broader than the thorax : antennae filiform, longer than the 

 thorax ; first joint long, slender ; second short-cyathiform ; third and 



* Callimome is allied to Gastrancistrus through C. nitidulus. C. cyaneus, 

 Kollar, approaches nearer than any other species that 1 have seen to Or- 

 myrus, which genus connects the Torymidce with the EucharidtB.
