width at apex), and its ocelli are large, but placed not far be- 

 low the supra-orbital line. The female apollincus has a short 

 malar space (about like that of incertus), but its ocelli are 

 small, and the sides of its head behind the eyes are much more 

 densely punctate than those of incertus. 



The eyes of the niveatus male are considerably swollen, and 

 its ocelli are placed at somewhat less than one-third of the 

 distance from the supra-orbital line toward the bases of the 

 antennae, being slightly above the narrowest part of the ver- 

 tex. Each of its lateral ocelli is a little less than its own diame- 

 ter from the nearest eye-margin. The size and relative posi- 

 tion of the eyes and ocelli of the male of reycli are about the 

 same as with the niveatus male. 



The Occurrence of Striking Peculiarities of Pattern 

 in Unrelated Chalcidoid Hymenoptera. 



By A. A. GIRAULT, Washington, D. C. 



In North Queensland I chanced upon the following exam- 

 ples of the occurrence of striking and peculiar color patterns 

 in unrelated Hymenoptera of the Chalcidoid series. There is 

 a number of very beautiful chalcid flies which have the head 

 and thorax metallic green or purple and the abdomen deep 

 golden yellow, margined down all, or part, of each side by the 

 metallic color. The peculiarity and unusualness of this kind 

 of pattern is such as to catch the eye at once and the first 

 species which I encountered was subsequently thought to be 

 very common from the fact that the pattern was taken as the 

 index of identity. However, later, these specimens were close- 

 ly examined and resulted as follows : 



A pirene miscogasterid, a eupelmid, an encyrtid, an aphe- 

 linine (Encarsia} and several other Eulophidae representing 

 two undescribed tetrastichine genera (two species in one of 

 them), an .-Iproslocctus, an Ootclrastichus and a Tctraslicluis. 

 Here we find represented three families of the series, live sub- 

 families, nine genera and ten species. The habits of none of
