UEMIPTERA— HETERUPTEIIA— LYG.EID.E. 397 



femora I should be inclined to place here two of the fossil species found at 

 Aix ill Provence (Oligocene) and heretofore referred to Pachynierus, viz, 

 P. fasciatus Heer and P. pulchellus Heer, which much resemble our first two 

 species. 



Table of the species of Liniitm. 



Membrane of the hemelytra distinctly marked with broad, arcuate, loiigitudiDal stripes. 



Thi)rax very rapidly narrowing iu the anteriiir fourth 1. L. Iwlinesii. 



Thorax narrowing only a little in the anterior fourth 2. L. putnami. 



Membrane of the hemelytra clear. 

 Corinm mostly obscure. 



Anterior outer angles of the thorax so rounded that the curve of the anterior half of the thorax 



is almost uniform 3. L. abolita. 



Anterior outer angles distinct though rounded 4. L. carcerata. 



Corium mostly clear. 



Cosral margin distinctly though rather narrowly testaceous ; rest of corium clear .5. L. evoluta. 



In addition to the thickening of the costal margin, testaceous blotches fringe the membranal 



suture and mark the outer tip of the corium 6. L. gravida. 



1. LlNN^A HOLMESII. 



PI. 23, Fig. 10. 



Head slightly broader than long, well rounded, the front entirely without 

 angulation. Thorax half as broad again as long, the sides strongly arcuate, 

 the anterior margin only about half as long as the posterior (in which point 

 it is wrongly represented ou the plate), which is slightly emarginate at the 

 base of the scutellum, tlie surface smooth. Hemelytra with the corium 

 very dark testaceous, de epening apically, with a pallid sutura clavi, and a 

 subcostal streak, besides a small triangular spot on the membranal suture 

 just without the sutura clavi ; membrane with four pale testaceons, equidis- 

 tant, slightly arcuate, longitudinal streaks, the outer occupying, respectively, 

 the costal and inner margins, originating at a little space beyond the mem- 

 branal suture and running to the outer margin, the interspaces perfectly 

 clear. 



Length of body, 3.35'"™; breadth, 1.1.5'"™; lengtli of antenufp., 1.4""". 



Named for Mr. W. H. Holmes, geologist, archeologist, and artjst of the 

 Hayden Survey. 



Florissant. One specimen. No. 2320. 



2. LiNN/EA HUTNAMI. 



PL 23, Fig. 4, 



This species closely resembles the preceding in general appearance, 

 but differs frttm it in important details in those pai'ts which can be com-
