2 28 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 



Philaronia Ball. 



Vertex, disc convex, sloping in line with pronotum, length on 

 middle twice that against eye, surface roughened, anterior margin 

 almost rectangulate, between eyes and tylus deeply sulcate and 

 somewhat refiexed ; tylus rounded anteriorly, lateral margins 

 slightly elevated, depressions lateral to weak median carina ; ocelli 

 placed close to posterior margin of vertex ; front inflated, slightly 

 anteriorly produced, acutely angled with vertex, disc convex, 

 coarsely ribbed lateral to median line; rostrum short and stout, 

 two-jointed, reaching middle coxae ; pronotum, disc convex, 

 sloping, anterior margin broadly rounded, lateral margins short, 

 divergent, equal to less than distance between ocelli, weakly cari- 

 nate, posterior margin emarginate; elytra coriaceous, parallel- 

 margined or convex, twice longer than wide, costal margins 

 sinuate, refiexed before middle, "venation irregular, ramose, the 

 two veins on the corium forking to form discoid cells, which are 

 broken up posteriorly to form an irregular network, which occupies 

 the entire apical portion of the elytra" ; dorsal surface closely and 

 finely punctate, sutural lines and venation usually obscured by 

 short, dense, yellow pubescence ; genitalia curved dorsally to 

 approximate elytral suture at apex. 



This genus, of but two species, was described by Dr. Ball when 

 he founded it, as composed of "stout, heavy-set, somewhat globose 

 forms of moderate size, having the form and dense hairy covering 

 of a Lepyronia together with the sulcate vertex of a Philaenus and 

 a ramose venation, which is quite distinct from the type of either 

 genus."

General form as mentioned in the key to species ; width across 

 costal margins of elytra one-third greater than at eyes; color 

 reddish brown, vertex and pronotum lighter. Length 5.5 mm. ; 

 width 2.5-3 mm - 



Vertex, length slightly greater than one-half width and almost 

 equal to length of pronotum behind it; tylus broadly rounded 

 before, length equal to width and greater than length of vertex 

 behind it; ocelli equidistant from eyes and each other; front 

 inflation and angle with vertex greater than in bilineata; prono- 

 tum, disc strongly convex, depressed in median line, entire anterior 

 third more or less depressed by a transverse row of pits, posterior 

 margin narrowly emarginate; elytra broadly convex, costal 

 margins strongly curved ; pubescence coarse.
