222 Mr, J. L. Hancock’s Studies of the 
4. A. fuscus, sp. nov. (or var. ?). 
Similar in stature to longinotus, but entirely fuscous (as in newu- 
osus), the vertex wide, and the frontal costa more roundly produced 
between the antennae, and sinuate below the median ocellus, the 
lateral margin of vertex with distinct lobes and marginate on each 
side forward. Dorsum of pronotum very strongly rugose, plentifully 
furnished with abbreviated rugze, and tubercles irregularly disposed ; 
in profile the median carina of pronotum strongly sinuate, little 
subnodulose forward, and distinctly depressed behind the shoulders ; 
lateral lobes little more reflexed outwards, the triangular posterior 
angle little more acute and somewhat spinose. Length of body entire, 
female, 18 mm. ; pronotum 16°8 mm. ; posterior femora 8 mm. 
One example from N.W. Borneo, R. Shelford; Oxford

7. A. robustus, sp. nov. 
A stouter form than either longinotus or rugosus, and like the 
latter having abbreviated wings and pronotal process not at all or 
very little extended beyond the knees of the hind femora ; dorsum 
between the shoulders rather broader ; colour ferrugineous or 
fuscous ; the vertex distinctly wider than one of the eyes ; lateral 
lobes of pronotum decidedly reflexed outwards, the posterior angles 
triangular but not at all spinose ; dorsum of pronotum strongly 
rugose and tuberculose ; the third articles of the posterior tarsi (in 
the female) little longer than the first or the second. Length of 
body entire, male and female, 13°8-15°4 mm. ; pronotum 13-14 mm. ; 
posterior femora 7-9 mm.
