Aptenopcdes robusta new species 



(PI. XVI, figs. 6 and 7; pi. XVII, fig. 5.) 



This insect may well be considered the most anomalous of the 

 genus. The penis is of entirely different type from that of any 

 other species. It is the most robust species of Aptenopedes but 

 agrees with the slenderest and most widely separated species, 

 sphenarioides Scudder, in having very small but extremely 

 narrow tegmina which reach to (female) or across (male) the 

 large tympanum. The rich pink tibiae in both sexes afford 

 another striking character. 



Undoubtedly another restricted type, the insect should be 

 sought in xeric sand areas along the east coast of Florida in the 

 Indian River region opposite Lake Okeechobee. 



Type. — $ ; Likely, Palm Beach County, Florida. July 24, 

 1934. (J. D. Beamer). [Hebard Collection, Type No. 1298]. 



Size moderately large and form very robust for the genus, the general 

 form showing greatest similarity to that of nigropicta here described. 

 Head in dorsal aspect similarly very blunt, but eyes much deeper and 

 general contour of head and pronotum otherwise more as in aptera coquinae 

 here described. Pronotum with definition between dorsum and lateral lobes 

 very feeble though suggested, sulci not conspicuous. Tegmina represented 

 by very narrow pads which expand feebly to their rounded apices, the latter 

 slightly surpassing the large tympana but the latter wider than their 

 vertical width. Furcula represented by two moderately stout, irregular, very 

 faintly divergent fingers, deeply inset due to the sudden and decided 

 emargination mesad of the tergite from which they spring, each twice as 

 long as broad beyond its basal weakly thickened portion. Supra-anal plate 

 rather narrowly shield-shaped, proximad medio-longitudinally concave and 

 weakly so laterad, a very small blunt tooth on each lateral margin opposite 

 cereal bases. Cerci narrowing strongly proximad, with remaining portion 

 very slender to the acute apex, directed dorso-caudad and failing to reach 

 as far caudad as the apex of the supra-anal plate. Paraprocts simple. 

 Penis remarkably distinctive; dorsal lobes produced, adjacent along their 

 inner margins, erect, curving caudad narrowly at apices where the distal 

 margin is broadly concave on each side, widened also distad so that a sort 

 of partial hood is formed; dorsal pair of parameres broad but not as 

 broad as the dorsal lobes, similarly produced dorsad and distad curving 

 caudad to project caudad narrowly beyond them with distal margin convex 

 on each side (thus this margin of each dorsal lobe is concave and of each 

 dorsal paramere convex), so that with the dorsal lobes they form a hood 

 above the broad, attingent, erect ventral pair of parameres, the latter
