fuscous longitudinal lines ; in others the lines arc not only 

 more distinct, but are connected here and there by cross 

 bands, and on the right hemelytron are joined before the 

 apex by a curved band. It is possible that more than one 

 species may be included, but as I have failed to find 

 structural differences, I have not ventured to separate any 

 but the following, and even it as only a more persistent 

 variety. 



23. S. socialis, var. sobrina. 



Exemplis typicis similis sed paullo major ac dilutior; 

 membrana sinistrorsa vix infiiscata ; femoribus posticis vix 

 fusco-notatis. 



Long. 3 mm. 



Hab. — Uru9aca, Rio Jurua (November, 1874). Many 

 specimens. 



24. S. seducta, n. sp. 



S. sociali, var. sobrince persimilis, sed statura paullo 

 majore, colore luteo-bruunea, et vertice paullo trans- 

 versiore videtur distincta. 



Long. 3 mm. 



Hab. — Kio Jurua (October and November, 1874). 

 Many specimens, " at light." 



It is with much hesitation that I have given this 

 specific rank. At first sight it looks quite different from 

 any form of socialis, but this is chiefly due to its yellow- 

 brown colour and rather larger size. Beyond these there 

 is no very tangible character by which to sej^arate it. It 

 is as variable as socialis in the markings of the hemelytra, 

 these being in some examples almost immarked, and in 

 others adorned with longitudinal and transverse fuscous 

 bands and lines of variable intensity. The head between 

 the eyes seems to be more decidedly transverse than in 

 socialis. 



25. S. simulans, n. sp. 



Fusco-brunnea, capite, pronoto, scutelloque disco dilu- 

 tioribus ; corpore subtus griseo-albido ; clavo marginibus 

 irregulariter, corio lineolis longitudinalis (in hemelytro 

 dextro prope apicem anastomosantibus) area marginal! 

 maculis 3, membrana ad apicem corii macnla 1 obscu- 

 rioribus ; membrana hemelytri sinistrorsi dilutissime 

 brunneo-fusca ; femoribus posticis subtus vitta longi-
