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 Ischnoptera ; these are 

 cinnamomea, basalis, punctifrons, aegrota and relucens. The type of 

 amplicollis cannot be found. Phyllodromia pulchella Gerst. should 

 be referred to the genus Theganopteryx (sub. fam. Ectobiinae). 



Ischnoptera basalis, Gerst. (Plate II, fig. 2). 

 Phyllo dromia basalis Gerstaecker 1. c. p. 63 (1883). 

 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 th 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 th tergite is hidden 

 beneath the 6 th , the 8 th tergite is fringed with hair and conceals 

 the 9 th 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-linc. Sub-genital lamina 

 asymmetrical, one style (the left), a deep notch on the right side. 

 Supra-anal lamina of $ subtriangular, apex notched.

S Head testaceous, a castaneous blotch between the eyes ; 

 frons flattened, maxillary palpi very slender, testaceous ; antennae 

 testaceous at base, remainder fuscous. Pronotum 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,

 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,
