3. A. longinotus, sp. nov. 
This species is closely allied to A. rugosus, Bolivar, and might 
possibly be the long-winged form of the latter. It differs principally 
in the pronotum being strongly extended backward beyond the 
femoral apices, and in the body being somewhat stouter. It bears 
moreover a near resemblance to nexuosus also, but it is smaller in 
stature. Ferruginous or tending to fuscous. Vertex wider than 
one of the eyes, very little narrowed forward, very slightly marginate 
on each side anterior to the lateral supraocular lobes, median carina 
abbreviated ; frontal costa very sparingly compresso-elevated between 
the antenna, in profile scarcely sinuate below the median ocellus, 
above declivous. Pronotum anteriorly truncate, posteriorly lengthily 
extended beyond the femoral knees; dorsum convex between the 
shoulders, subbifossulate behind them, the surface rugose, irregularly 
furnished with abbreviated rug and tubercles, posterior angle of 
the lateral lobes triangular, somewhat acute, but not spinose, Wings 
little longer than pronotum in the female. Anterior and middle 
femora margins subentire, the posterior femoral margins minutely 
serrulate. Length of body entire, male and female, 16°5-19 mm. : 
pronotom 16-17°5 mm. ; posterior femora 6°5-7°6 mm, 
Seven examples from N.W. Borneo, R. Shelford; Oxford 
Museum.
