Tue single Ichneumonid in Mr. Farquharson’s collection, 
though represented by only one example with defective 
antennae, has proved to be of great interest. A prolonged 
study of this specimen convinced me that it must be 
assigned to the Joppinae, and further that it was referable 
to no. described genus. At my request Dr. A. Roman of 
Stockholm examined the insect, and his opinion as to its 
systematic position agrees with that just expressed. For 
this kindness and further for drawing my attention to 
the importance of the host attachment (vide infra) of this 
new genus I desire to express my hearty thanks. 
The genus Adelotropis (Gdnloc, todmic) is easily recog- 
nised by antennal and neurational characters and the 
genotype in all probability by colour and puncturation., 
Fam. ICHNEUMONIDAE. 
Sub-fam. JOPPINAE. 
Adelotropis, gen. nov. 
Head as wide as thorax. Frons smooth, without carina between 
the antennae. Face medianly raised, the swelling defined with 
moderate sharpness just below the toruli and fading out towards 
the clypeus. The latter not separated from the face medianly but 
shallowly at the sides (towards the ends of the tentorial apodemes). 
Inner orbits a little divergent towards the mouth edge. Occiput 
and genae smooth. The latter slightly swollen posteriorly so that 
in profile the genae are not margined. The occipital margin, fine 
but distinct and thinning out ventrally, reaches the mouth edge as 
a delicate line perceptible only from behind. The first normal 
funicular joint (post annellus) shorter than the second which is 
longer also than its successors. Thorax robust; notauli shallow 
and indistinct; scutellum deeply separated from scutum and 
bluntly, conically, elevated with a broad raised flange which is 
apically defective. Propodeon dorsally short, deeply separated
