rows of punctures, the rows separated only at the base of the elytra 

 by an obscure costa. 



The female differs from the male in having the antennae a little 

 less strongly dentate. 



It is difficult to decide whether Lycns rujipennis, F., should be 

 considered identical with P. erythropterum, Kr., or with P. sale- 

 brosum, \V. 1 have here adopted Erichson's view, by which the 

 latter becomes synonymous with the Fabric! an species. 



Metriorrhynchus hsemorrhoidalis. 



Porrostoma hsemorrhoidale, JFaterh., Trans. Ent. Soc, 1877, p. 79, 

 pi. ii. figs. 61o-64a. 



Elongatus, parallelus, niger ; elytrorum apice rufo ; elytris qua- 

 dricostatis, interstitiis biseriatim cancellato-punctatis. d , ? .

Dull black. Eostrum shorter than broad. Thorax small, divided 

 above into seven areolets. Elytra with the four costae distinct ; the 

 interstices with two rows of large irregular punctures, the rows not 

 divided by a distinct costa ; the apices are red. 



This species resembles M. scalaris, but is much longer and nar- 

 rower, and the rows of punctures on the interstices of the elytra 

 are much more regular. 



Lycus atratus, Fabr. (Syst. El., ii. p. 113) may perhaps be a black 

 variety of this species, and both are possibly varieties of rufi- 

 pennis, F. 



Metriorrhynchus plagiatus.

Porrostoma plagiatum, Waterh., T?-am. Ent. Soc, 1877, p. 80, pi. ii.

Ater ; elytris marginibus apiceque rubris ; rostro latitudine 

 breviori, utrinque impresso ; antennis bene dentatis. cf .

Rostrum very short, shorter than broad, compressed in front, 

 with a deep impression in front of the eye. Elytra deep red, with 

 a black patch extending from the scutellum to the posterior two 

 thirds, somewhat in the form of an A; quadricostate ; the inter- 

 stices with two rows of punctures, not separated distinctly by a 

 carina. 



Possibly this is a variety of the foregoing species.
