and fourth indistinct; fifth white above, a Httle shorter than the 

 second; the following linear, very compact, successively decreasing 

 in length: chest spindle-shaped : fore- chest broader than long, rounded 

 in front, much lower than the middle-chest, very finely shagreened : 

 shield and scutcheon of the middle-chest very largely and deeply 

 punctured : shield rather flat, adorned with a broad coppery band 

 whose edges are tinged with blue and purple ; sutures of the parap- 

 sides distinct ; axillae parted by about one-third of the breadth of 

 the chest ; scutcheon obconical, with a coppery spot at its base : hind- 

 chest small, subquadrate, finely punctured, with two or three slight 

 cross ridges : propodeon and podeoi\ short : abdomen lanceolate, 

 longer and a little narrower than the chest, slightly pubescent, trans- 

 versely and very finely striated, almost flat on the disc towards the 

 base, adorned above with coppery purple and blue colour ; metapodeon 

 of moderate length ; octoon shorter ; ennaton longer ; decaton shorter ; 

 the three following segments short ; underside finely punctured, not 

 keeled, dorsal segments approximate beneath, parted only by two 

 linear, parallel, very slender plates which extend along the whole length 

 of the body : legs green, slightly pubescent, adorned with blue and 

 purple colour : fore-thighs rather thick ; fore-shanks purple, armed 

 at the tips with a slender curved spine ; fore-feet pitchy, tawny at 

 the base ; middle thigh long and slender, grooved beneath ; tip of 

 each middle shank armed with a stout straight tawny spine ; middle 

 feet black, pale yellow at the base ; hind-legs formed like those of 

 Chalcis ; hips long ; thighs very large, armed beneath with seven 

 oblique teeth, those towards the tips are small ; shanks very much 

 curved, widening from the base to the tips ; hind-feet pitchy, with a 

 slight metallic tinge : wings almost colourless, fore-wings slightly 

 clouded with brown in the disks and with gray at the tijDS ; veins 

 black ; humerus much more than one-third of the length of the wing ; 

 ulna about one-third of the length of the humerus ; radius nearly as 

 long as the humerus, extending almost to the tip of the wing ; cubitus 

 straight, very slanting, less than one-fourth of the length of the radius, 

 widening from its source to the brand which is small ; a few supple- 

 mentary veins in the disk, as is usual in the large species of the tribe. 

 Length of the body 5 lines ; of the wings 6 lines.

This is one of the tropical forms whose characters are more com- 

 pound or complicated than those of any genera which inhabit more 

 temperate regions ; and may be considered either as a connecting 

 link between families, or as a common and governing centre, repre- 

 senting various remote groups, and associating them together. It 

 comes between the PteromalidcB and the Eupelmidce, and is one of 

 the Cleonymidce, and is most allied to Lycisca ; but it has the head 

 of Perilampus, the thoracic sculpture of the PeriIa7npid(E and the 

 Eurytomidce, and the hind-legs of the LeucospidcB and of the ChaU 

 cidce. ~--'i'i^.
