NEW SPECIES OF INDIAN CHRYSIDID^. 



By Major C. G. Nurse, Indian Staff Corps. 



(Continued from vol. xxxv. p. 308.) 



The next seven species are quadriclentate, and as the identi- 

 fication of the Indian quadridentate Chrysididse is by no means 

 easy, I have made out the following key, which should be of 

 assistance in separating them. It will be observed that at least 

 two species, viz. C. gujaratica and C. lucinda, have the sexes 

 dissimilar, the female only having golden or coppery effulgence. 

 I have taken both sexes of these species under circumstances 

 which leave no doubt as to their affinity : — 



A. Teeth of 3rd abdominal segment more or less acute. 



a. Abdomen with golden or coppery effulgence. 



a}. 1st, 2nd, and 3rd segments with golden or 

 coppery effulgence. 

 a^. Stoutly built ; length 7-10 mm. 



a?. Thorax bright metallic green gujaratica 2 • 



b^. Thorax steel-blue cupreiventris. 



Ir'. More slenderly built ; under 7*5 mm. 

 a^. 1st segment of tarsi very light testa- 

 ceous zobeida. 



b^' 1st segment of tarsi dark reddish black quettaensis. 

 b^. 1st and 2nd segments with golden or coppery 



effulgence lucinda ?. 



c^. 2nd and 3rd segments with golden or coppery 



effulgence ciKtocrata. 



d^. Two spots on apical segment with golden 



effulgence specnlata. 



b. Abdomen entirely blue or green. 

 a^. Wings more or less fuscous. 



a^. Head smaller than pronotum fuscipennis. 



b^. Head as large as pronotum cotesi. 



b'^. Wings entirely hyaline. 

 a^. Green or bluish-green. 



a^. Stoutly built ; length 7-9 mm. 



a^. Tegulffi green lucinda 3'' 



b*. Tegulffi blue gujaratica 3" . 



¥, Slenderly built ; under 7 mm. 



rt*. With subapical fovese balucha. 



b*. Without subapical fovese obliterata. 



b^. Blue or greenish blue. 



a^. Head, thorax, and abdomen of equal width, 

 a*. Lateral teeth of 3rd abdominal seg- 

 ment much shorter than median bahadnr. 

 ft*. Lateral teeth not much shorter 



than median thnlia. 



¥. Head, thorax, and abdomen not of 



equal width seraxensis. 



B, Teeth of 3rd abdominal segment distinctly blunt... hoggei.
