HAUPALIDiE. OMASEUS. 115 



gitudinal stria : elytra slightly convex, striated, the striae obsoletely punctate, 

 with three discoidal impressions, and a series on the margin: legs and 

 antennae black. 

 Var. IS. With the striae of the elytra confluent. I have here noticed this variety, 

 from Panzer having figured it, for the purpose of remarking that similar 

 variations frequently occur amongst the Harpalidae, and, consequently, that 

 they are not characteristic of specific differences. 



Very common beneath stones and moss, throughout Britain.

Very glossy black : head very smooth, impunctate, with an impression on each 

 side of the forehead: thorax very glossy, smooth, subcordate, impunctate 

 behind, with two longitudinal striae, the inner longest : elytra rather deeply 

 striated, the striae obsoletely punctate, with three impressed dots on the disc, 

 and a marginal series: body beneath black: antennae, legs, and palpi pitchy 

 rust-colour. 



This appears to be the Ca. IobvicoIUs of Duftschmid's Fauna; but as the specific 

 character alone is in Latin (the rest of the description being in German), it 

 is difficult to determine, amongst such closely approximating species, which is 

 the one intended ; in size it agrees : it resembles an Argutor, but may be 

 known from the species of that genus by the elongation of the striae near the 

 scuteUum. 



Few specimens only have occurred ; they were captured near 

 London. 



t Sp. 7. rufifemoratus. Ater, nitidus, femorihus rufis. (Long. corp. } lin.) 

 Om. rufifemoratus mihi. — Steph. Catal. p. 24. No. 192. 



Very like Om. Nigrita, but with the thighs rufous. 



I regret being unable to say more of this insect, which is said, 

 by Mr. Haliday, in the Zoological Journal, No. 11, to occur not 

 uncommonly confined to one spot in the neighbourhood of Belfast, 

 in Ireland : it may, probably, be synonymous with some of the 

 continental species with rufous femora. 



b- With rudiments of wings only.

Glossy black : head with an irregular impressed line between the eyes on each 

 side : thorax obsoletely wrinkled transversely, the base impunctate, with a 

 deep rugose fovea at each angle, having two longitudinal stria;, of which 

 the inner is longest: elytra deeply striated, the striae punctate, with three
