10. Hemelytra entirely or nearly entirely opaque or sericeous-opaque; 



both veins of corium obsolete; embolium discolored; interior 



areole reaching apex of membrane Micracanthia, p. 415 



Hemelytra greasy-shining, with sericeous black spots ; corium with 

 exterior vein distinct and the interior ones also distinct at base; 



interior areole set distinctly above apex of the second areole 



[Teloleuca] 



11. Pronotimi (brachypterous form) with posterior sulcus to callus 



placed far behind the middle ; entire hemelytra very shining, in 

 the brachypterous form entirely coriaceous ; convex, membrane 

 scarcely differentiated. Ocelli scarcely separated from each 



other Lampracanthia, p. 415 



Pronotum (in brachypterous forms also) with the posterior sulcus 

 to callus placed slightly or but little behind the middle (apical 

 stricture not_ included). Hemelytra flat, sericeous-opaque, 

 embolium polished, white-marked. Ocelli contiguous, set in a 

 distinct elevation [Chartoscirta] 



Pentacora Reuter. 



This genus corresponds with the division Uhler made in his 

 1877 monograph of the family to contain the species having five 

 areoles or cells in the v^^ing membrane, and in connection with 

 other less obvious characters sufficiently fixes the family. The 

 cells are elongate, fairly narrow, and complete. At times there 

 is a cross vein dividing the long cell into two parts, more or less 

 unequal, but this is not even a specific character, being found j.mly 

 in a specimen here and there. The species of the genus seem to 

 be found on saline beaches by preference. The table following 

 separates our five species. While there seem to be no Connecticut 

 records of some of them, this must be because of absence of col- 

 lecting rather than from lack of the species. All are found on the 

 Sound shores of Long Island and New York on the mainland. 



Nothing seems to be known of their life histories. 



Key to Species. 



1. Species glabrous, polished, covered on the upper part of the body 



with long erect dark hairs 2 



Species with upper part dull, pubescent, with or without dark, 

 erect or recumbent hairs 3 



2. Antennal j oint four much longer than one hirta 



Antennal joint four slightly longer than one pellita 



3. Margins of the prothorax and corium without spines 4 



Margins of the prothorax and corium with a single row of short, 



stout spine-like bristles .^ signoretii 



4. Prothorax four times as wide as long; explanate margin narrowly 



luteous with a black reflexed edge; hemelytra with short, erect 



hairs ligata 



Prothorax three times as wide as long ; margins concolorous, with 

 a wider black reflexed edge ; hemelytra with very short recum- 

 bent, almost bristle-like hairs sphacelata
