2 Cryptus sp., Hemiteles spp.—In my former article there are 
some remarks upon three species of Ichneumonide, under these 
headings. Mr. Weston has again met with these interesting 
species in some abundance, so that a more satisfactory account 
can now be given of them. I may say that all were led into error 
two years ago by several of the specimens having their abdomens 
so compressed in setting that the male genitalia were protruded ; 
these were erroneously taken to be females. Last year many true 
females were bred, but with the two sexes these interesting species 
were most puzzling. They were fully examined by Dr. Capron 
and Mr. Bridgman, on more than one occasion. First, we 
agreed they belonged to the Pimplide, and came near Hehthrus or 
Clepticus; then we thought they might be found amongst the 
uncertain genera at the end of the T'ryphonide; at last we came 
back to the old determination, and settled they must be Cryptide, 
and come near Hemiteles. They proved so puzzling that Mr. 
Bridgman wrote me: “The species without a perfect areolet 
might come in Hemiteles; if the petiole were more slender they 
might squeeze into Atractodes (Ophionide), or if the hinder claws 
were pectinated they might belong to Phytodietus ; as it is I think 
they must belong to the cubical-headed Pimplide.” Again he 
writes: ‘In going over my collection I came on three little black 
males, which I tried as everything last winter, and at last left 
them at the tail of Phygadeuon. I am now delighted to recognise 
them as the males of Weston’s genus.” Dr. Capron was equally 
puzzled between a Cryptid and Pimplid location. Last November 
I sent thirty specimens (males and females of the two species, and 
females of the third) to Dr. Kriechbaumer, and he wrote: ‘“ Your 
three species are quite unknown to me, and doubtless they form 
a most compact genus. They agree pretty well with the Cryptide, 
but remind me in many respects (head, antenne, and structure of 
metathorax) of the Xylonomide. Species 2 and 3 Gravenhorst 
would, I think, have placed with Hemiteles. The species also 
have a great family likeness to Lissonota, and may possibly 
belong to the Pimplide.” He then makes some further detailed 
remarks, and says, ‘Shall not you write a short monograph of 
this interesting genus?” Mr. Bridgman has undertaken this,
