the species described by Gerstaecker in 1883 from the 
Cameroons district (Mitt. Ver. Vorpomm. XIV) and I find that 
several of the species referred in that memoir to the genus 
Phyllodromia, belong really to the genus Jschnoptera; these are 
cinnamomea, basalis, punctifrons, aegrota and relucens. The type of 
amplicollis cannot be found. Phyllodromia pulchella Gerst. should 
be referred to the genus Theganopteryr (sub. fam. EHctobiinae).

The male exhibits a most remarkable modification of secon- 
dary sexual characters, quite unparalleled amongst the other 
members of the genus or even sub-family. From beneath the 
posterior angle of the 6™ abdominal tergite projects backwardly 
on either side a narrow lanceolate strip of chitin, terminating in 
a knob beset with fine setae; these processes extend, as far as 
the middle of the supra-anal lamina. The 7 tergite is hidden 
beneath the 6, the 8" tergite is fringed with hair and conceals 
the 9 tergite; the supra-anal lamina is strongly produced, 
exceeding sub-genital lamina, it is depressed at the base, the 
depression being delimited by three carinae arranged in a triangle, 
the opening of the scent-glands at the apex of the triangle, a 
tubercle near the centre of the base-line. Sub-genital lamina 
asymmetrical, one style (the left), a deep notch on the right side. 
Supra-anal lamina of 2 subtriangular, apex notched.

3 Head testaceous, a castaneous blotch between the eyes; 
frons flattened, maxillary palpi very slender, testaceous ; antennae 
testaceous at base, remainder fuscous. Pronotam trapezoidal, 
anteriorly scarcely covering vertex of head, posteriorly obtusely 
angled, sides deflexed, piceous, lateral margins and a large spot 
on the posterior part of the disc, fusing with the lateral margins, 
testaceous. Tegmina considerably exceeding the apex of the 
abdomen, castaneous at base becoming testaceous at apex, mar- 
ginal area and a transverse fascia running from margin towards 
apex of anal field, testaceous; 13 costals, radial vein bifurcate, 
the lower branch multiramose, the rami reaching the apex of the 
tegmen, discoidal sectors oblique, anterior ulnar vein multiramose, 
posterior ulnar simple. Wings testaceous, mediastinal vein tri- 
ramose at apex, 9—10 costals, ulnar vein 7-ramose, a minute
