Mr. W. F. Kirby on two new Species of Chalcididse. 243 



XXII. — Descriptions of two new Species of Chalcididae. By 



W. F. Kirby, Zoological Department, British Museum. 

 My valued correspondent, Prof. Berg, of" Buenos Aires, has 

 just forwarded to me for examination a small box containing 

 three species of Chalcididae. One of these is apparently 

 identical with Chalets Mnestor, Walk. (Ent. i. p. 219, 1841), 

 the others I describe here as new. My colleague, Mr. O. 

 Waterhouse, will figure the Leucospis shortly in his l Aid to 

 the Identification of Insects.' Prof. Berg has also called my 

 attention to the fact that Smicra Bunneisteri, Kirb., was not 

 taken in the Argentine Republic, as I had supposed, when I 

 described it, but was bred by Mr. Burmeister in Rio Janeiro 

 from a species of Galigo. 



Leucospis coxatis. 



Exp. al. 9 lin., long. corp. 4 lin. 



Female. Black, thickly and closely punctured, and with fine 

 silvery-grey tomentum ; head with green reflections above, 

 brightest between the antennae, and (narrowly) round the eyes, 

 and more coppery behind ; the face, which is deeply impressed, 

 nearly as in Metallopsis cayennensis, is likewise greenish, 

 especially above; thorax black, with very slight greenish 

 reflections ; prothorax bordered with rufous on the sides, and 

 in the middle in front, and bordered with yellow behind ; 

 mesothorax with a transverse yellow stripe (?) behind (obli- 

 terated in the middle by the pin) ; tegulae rufous ; antenna} 

 broken (first three joints black above, reddish below, scape 

 with an oblong yellow spot beneath) ; scutellum bordered 

 behind with a yellow crescent ; abdomen with the first seg- 

 ment constricted ; black above, with three yellow stripes near 

 the extremity, the last two bordering the base of the ovipositor 

 on each side, the slenderer portion of the ovipositor rufous and 

 recurved nearly to the scutellum ; mesopleura black, with a 

 slight greenish reflection and with a yellow streak beneath ; 

 metapleura with an oblique rufous streak, yellowish above, 

 running to the base of the hind coxa) ; legs mostly rufous, 

 varied with brown, and tibia) streaked with yellow ; hind 

 coxae rufous above the middle, this colour being bordered 

 above and below with yellow ; lower half dark brown ; hind 

 femora cupreous on the outside, bordered, except at the base 

 and tip, with yellow, and armed beneath with numerous small 

 teeth ; fore wings clouded, inner margin and hind wings lighter. 



Allied to L. tume/itosa y Kirb., by the constricted first seg- 

 ment of the abdomen, but in coloration more like L. cana- 

 densis, Walk., and allies.
