In other respects the species agree closely. The male of fitchii 

 which is before me differs from that of vertebratus, and also 

 from the female of fitchii, in that the wings fall slightly short of 

 the apices of the fore tarsi instead of extending a little beyond 

 them ; this may be a variable character and I do not make use of 

 it owing to lack of material for comparison. 



I have seen the pupa of another species of Promachus, to 

 which I have been unable to assign a species name. It agrees 

 with vertehratus in the structure of the lateral cephalic process in 

 having the upper thorn simple, but the upper cephalic thorns are 

 similar to those of fitchii, and the lateral process has the thorns 

 shorter than in vertehratus. As in the other two species there 

 are only 3 postspiracular thorns on the first abdominal segment; 

 the transverse dorsal armature is very similar to that of fitchii in 

 as far as the lateral areas are concerned, but there are no short 

 thorns between the long ones on the seventh dorsal segment, and 

 the apical segment has the upper pair of thorns much swollen at 

 base and ending in rather long sharp points, while the 2 small 

 thorns are stronger and the ventral posterior margin has also 2 

 small thorns. The length of this species is 14 mm. 



Vertehratus and fitchii are predaceous on white-grubs, Phyl- 

 lophaga {=Lachno sterna) spp., the larval habits of the uni- 

 dentified species are unknown to me. 



I take this opportunity of intimating that the pupa which I 

 described under the name Promachus milherti in the paper previ- 

 ously referred to, is correctly identified. I had some doubt about 

 the identity when I wrote the paper as the exuvia were not con- 

 nected with reared imagines ; but since the paper appeared I 

 have had the opportunity of examining a reared specimen which 

 confirms my tentative identification. 



OPEROPHTERA (RACHELA) BRUCEATA HULST.

In Entomologica Americana, Vol. VI, pp. 123-24, Dr. Geo. 

 D. Hulst describes this species. He says : " The female of this 

 species (I have several before me) is almost entirely wingless.
