proceeds above the sternum to the middle coxae. The mesonotum has a scattered 

 fuscous pubescence ; the breast with shorter, closer, and paler pubescence ; the coxae 

 (especially the posterior) on the lower side with dense long woolly hair ; the rest of 

 the legs bear a short scattered pale pubescence. The femora are green on the outside, 

 internally violet-black ; the anterior tarsi fuscous. The head and thorax are marked 

 with violet and purple tints. 



Note. — The following subfamily has been omitted from its place. It should have 

 followed the genus Orasema on p. 105 : — 



Subfam. PEBILAMPINjE. 

 This is a group of small extent, but has representatives in most parts of the world — 

 in America, Europe, in the Oriental Eegion, in South Africa, and Australia. 



EUPERILAMPUS. 



Euperilampus, Walker, Notes on Chalcidae, p. 67. 



This genus only differs from Perilampus in the " scutellum extending hindward and 

 forming a long stout spine," while the scutellum of Perilampus is not elongated. It 

 contains at present only one species.

Fam. ICHNETJMONmai. 



The species of this large family have been very little collected or studied beyond 

 Europe and North America. The exotic species have been altogether neglected, and if 

 they are as numerously represented in the warmer regions of the globe as they are in the 

 temperate an immense amount of work has yet to be done before our knowledge of the 

 tropical Ichneumonidae will be on a level with what is known of the European or 

 North- American forms. 



Our present systems of classification have been based entirely on European species. 

 So far as the division of the species into families is concerned the systems of Wesmael 

 and Holmgren appear to be natural enough, and it is generally possible to place the 

 tropical species in them without rearranging the definitions given by the above-mentioned 

 authors ; but, so far as my experience goes, the definitions of the subgroups are quite 

 inadequate. For example, the Ichneumonides Oxypygi, and Ichneumonides Amblypygi, 

 of Wesmael are suitable enough, for European species ; but we find so many gradations 

 in the form of the abdomen among the Central-American species that it becomes 

 impossible to say whether a particular species is referable to the first or the second
