Family THYRIDIDAE. 

 2. Hypolampnis minutula (?). 



Siculodes minutula Saalm., Ber. Senck. Ges. 1880 p. 295 ; Saaltn., Lep. 

 Madag. p. 216, t. 5. f. 59 (1891). 



SaalmUller's description of his species is not very fnll ; but, judging from liis 

 figure as well, I am disposed to refer here 2 6 S in the Triug Museum, one 

 from Mombasa Island, October ISOO (Dr. Ansorge), the otlier from Dar-cs-Salaam, 

 German East Africa, the latter larger than the Mombasa example : both of these 

 have veins 8, 9, of forewing stalked, and must be referred therefore to Htjpo- 

 laniprus. 



They have the hindmargin of hindwing sinuous, iucnrved below apex. This 

 will separate them from the species described below, U. certicalis, from the Niger 

 district, which has the hindmargin quite straight, but bears otherwise great 

 resemblance to them. 



3. Hypolamprus verticalis sp. nov. 



Foretdngs : fulvous brown, with dark brown markings, which are mainly 

 vertical ; one or two indistinct lines near base, a fascia with darker edges just 

 before middle ; two narrower postmedian fasciae, the second of which is interrupted 

 below middle, and a narrow submargiual line ; fringe concolorous ; a deeper brown 

 shade on hindmargin below middle, narrower towards the lower angle of cell. 



Hindwings: with 3 or 4 dark brown lines, and a few fainter reticulations : a 

 black-brown shade along middle of hindmargin and at anal angle ; the costal region 

 paler quite to apex. 



Underside with the markings more broken up. Head, thorax, and abdomen 

 all brown. 



Expanse of wings : 16 mm. 



One c? from Anambra District, River Niger. 



The hindwings are prominently triangular, the apex bluntly prominent, the 

 hindmargin nearly straight. It is allied to U. minutula Saalm., from Madagascar 

 and the East Coast of Africa, of which it may be a form. 



4. Isothauma (?) serraticornis sp. nov. 



Foreicings : semi-transparent, shining white ; the costa with seven pinkish 

 brown darker-edged spots, the intervals between them small, rosy white ; from 

 the edges of the brownish sjsots run faint rufous lines across the wings, most of 

 which become faint below the middle; marginal area with shorter, darker, irregularly 

 crooked lines edged with rosy ; apical region varied with minute dark specks ; 

 marginal line rosy, thickened into spots at end of veins, which jiroject into the 

 silvery white fringe. 



Hindwings : except for the costal markings, similar. 



Underside the same, with the markings brighter and plainer : the retinaculum, 

 which is in the form of a triangular projecting fold, covered with brownish and 

 silvery scales ; two tufts of pink scales close to base, and a line of silvery scales 

 above the subcostal vein. Head and palpi brown ; second joint of palpi white at 

 the apex : thorax and abdomen white, the latter rosy-tinged on anal segments ; 

 legs whitish tinged with rosy.
