Coloration in general m in A insignia, in the type the proximal articlei 

 antennae but lit t It* darker than the oth< i 



Antennae shorter; the fifth article shorter in comparison with the third 

 The first tergite differs from thai of I he two other species in having s oai 



rim in front beneath I he free border and toward its caudal edge, I bis i im fitting 

 with its lower edge against the head and expanding laterally into the usual end 

 In the type it also differs in having twelve border lobes instead of 

 only ten, the end lobes being subdivided; but in the young paratypical speci- 

 mens the end lobes arc large but aol subdivided; whether always subdivided 

 in adults it is impossible at present to say. The lobes of the keels in number 

 and arrangement as in the other species. The marginal teeth more rounded 

 than in A. insignia. Upper surface of tergites Btrongly densely tuberculate, 

 the large tubercles of the four longitudinal rows prominent A Bpecial eleva- 

 tion or tubercle on base of caudolateral lobe of each porigerous keel; on the 

 other keek a very prominent elevation proximad of the middle lobe. Differ- 

 ing in that the caudolateral angles of the sixteenth keels are not or BCarcely 

 produced caudad beyond caudal margin, the seventeenth but little so, and 

 the processes of eighteenth and nineteenth proportionately shorter. Dorsal 

 cones of anal tergite large, not fully reaching end of cauda proper. 

 Length, 9.5 mm.; width, 1.6 mm.

Distinguished from A. atopus and insignia in the structure of the 

 gonopods. These are in general very similar. But they are shorter, 

 reaching only to the anterior end of the prozonite, and are more 

 strongly bowed mesad; the dorsal curve and the constriction at distal 

 end less pronounced; the distal divisions are shorter and the mesal 

 one on each side extends at first nearly horizontally mesad and then 

 runs cephalad, the latter portion shorter than the former, crossing 

 the one from the opposite gonopod, widely separated from the outer 

 lobe and not extending distad beyond it or scarcely so. The apical 

 division or blade with total length but two and a half times the great- 

 est longitudinal diameter of the coxa as against three and a half times 

 in A. atopus. 



Coloration similar to that of A. atopus excepting that the back- 

 ground of the metazonites above is h 1 avoirs with the dark brown or 

 dusky color mostly confined to the coarser tubercles; first tergite 

 entirely dark; ventral longitudinal fulvous band of keels more sharply 

 limited than in atopus.
