REVISION OF LEUCOSPIDAE 89 



than the first, moderately swollen, convex except for deep percurrent ovipositorial groove; 

 dorsally coarsely punctured, punctures elongate and partly confluent, becoming much finer 

 and very dense at hind margin and laterally where also pubescence is very dense. Sixth tergite 

 and epipygium less densely pubescent and more regularly, mostly moderately coarsely punctured. 

 Ovipositor reaching base of fifth tergite.

In the key this species comes nearest to L. nigripyga sp. n. but seems to be close 

 also to L. speifera Walker, L. robertsoni Crawford and to L. enderleini Ashmead, 

 i.e. to species with unusually raised median carina of the propodeum.

Only one female is known of this distinctive species which belongs to the speifera- 

 group, in which it seems to be closely related to the species with rather short 

 ovipositor, viz. L. nigripyga sp. n., L. versicolor sp. n., L. robertsoni Crawford and 

 L. enderleini Ashmead. L. sumichrastii has a narrow smooth streak on hind coxa 

 (in the upper part of the depression) and very long genae as L. nigripyga and L. 

 versicolor, but differs from both in many other characters including the shape and 

 pilosity of the propodeum and gaster, as indicated in Text-figs 100 & 101 and 

 given in the key. Under the thick hairs (which is an unusual character within 

 the group) the pale red propodeum shows some coarse rugae, the submedian ones 

 probably analogous to the raised keels in L. enderleini and L. robertsoni, but the 

 median carina is very low.

Leucospis robertsoni Crawford 



Leucospis robertsoni Crawford, 1909 : 51-52, $ $. Holotype $ (?), U.S.A.: S. Florida (USNM). 



Dr Burks kindly submitted specimens compared with the type-material. 



The species has been known only from the south-eastern U.S.A., where all 

 specimens show a more or less extended rufinism, which is not known to me to occur 

 in the Mexican specimens. In these also the orange-red bands on the pronotum 

 posteriorly, on hind femur dorsally and ventro-basally and on hind tibia are yellow.
