Rico, at about 3,000 ft., by P. J. Darlington (May, 1938).

Muir 1926 Proc. Haw. Ent. Soc. VI, 2:335. 
Genotype, A. ornatus Muir loc. cit. 336. 
Head with eyes a little more than half width of pronotum. 
Vertex longer than wide expanding to base which is shallowly 
emarginate; median and lateral carinae well developed, curving 
uninterruptedly on to frons; no transverse carina. Frons longer 
than its widest part (1.4 to 1), base scarcely half as wide as 
apex, sides expanding to nine-elevenths from base, then evenly 
converging to apex, median carina distinct, lateral margins 
slightly raised. Clypeus at base four-fifths as wide as widest 
part of frons, tapering acutely to apex, median carina distinct, 
lateral margins slightly raised. Frons in profile slightly convex 
sloping into vertex in a somewhat acutely angulate curve; cly- 
peus almost flat; no median ocellus; genae slightly tumid be- 
low antennae; no subantennal process; antennae with basal 
segment very short, second segment slightly longer than broad, 
eyes widely emarginate ventrally. Pronotum three-quarters as 
long as vertex, anterior margin of disc convex, posterior margin 
shallowly excavated, curving anteriorly at sides, median carina 
prominent, lateral carinae of disc present, incurved anteriorly, 
lateral margins carinate between eye and tegula. Mesonotum 
feebly convex, tricarinate, hind portion only slightly depressed, 
tip of scutellum acute. Hind tibiae unarmed. Tegmina with 
sides expanding distally for three-quarters of length, almost 
symmetrically rounded at apex; clavus not granulate; apex of 
clavus situated three-quarters from base of tegmen; costal cell 
wide, slightly expanding apically, Sc+R joined to near stigma, 
common stalk Sc+R+M half as long as basal cell; typically 
seven or eight apical cells, the first two (or three) with curved 
sides, followed by a smaller triangular cell; second cell of M 
long with lateral margins decurving distally; distal portion of M 
curving posteriorly; third cell of M curved, subtrapezoidal, first 
cubital triangular or even semilunate, posterior cell pentagonal; 
a subapical series of four cells, the anterior forming a quarter 
circle, second rectangular, third pentagonal, fourth quadrangu-
