104- MANDIBULATA. COLEOPTEKA. 



Sp. 3. impressus. Elongatus, olivaceo-fuscus, villosus, subtilissims punctatus, 

 thoracis disco bifoveolato. (Long. corp. 2—2^ lin.) 



Pa. impressus. Curtis, ii. pi. 80. — Steph. Catal. p. 54. No. 546. 



" Olivaceous-brown, minutely punctured, villose : thorax with a fovea on each 

 side, near the base, equidistant from the margin and each other : elytra with 

 seven or eight obscure punctured striae on each : serrated mass of antennae, 

 thighs at the base, apex of tibiae, tarsi, and claws, ferruginous : beneath fer- 

 ruginous-olive, with ochraceous pubescence." — Curtis, 1. c. 



This also appears to be a variety of Pa. prolefericornis, as I have several speci- 

 mens of that insect in which the thoracic foveae are more or less evident. 



Taken near London ; in Battersea-fields : and I believe in 

 Norfolk. 



Sp. 4. auriculatus. Ovatus, niger, hirtus, crebre punctatus, pedihus rufo-piceis. 



(Long. corp. 2 — 2^ lin.) 

 Dr. auriculatus. Olivier. — Pa. auriculatus. Steph. Catal. p. 54. No. 547. 



Ovate, black, hairy : head and thorax rather deeply punctured, a little glossed 

 with fulvescent, the margins of the latter very narrow anteriorly ; scutellum 

 fulvescent : elytra rather shining, deeply punctured, and clothed with rather 

 distant, erect, fuscous bair : body pitchy-black beneath, with fulvescent pu- 

 bescence : legs rufo-piceous, the tibiae dusky. 



Less abundant than Pa. prolefericornis ; and seldom taken near 

 London. <e Wandsworth-common." — Mr. Westwood. 



f Sp. 5. bicolor. Niger, subtilissime punctatus, elytris, pedihus antennisque fer- 



rugineis. (Long. corp. 2 lin.) 

 Pa. bicolor. Curtis, fo. 80.— Steph. Catal. p. 54. No. 548. 



" Minutely punctured, with coarse, imperfect striae at the base of the elytra : 

 head and thorax black ; elytra, legs, and antennae, ferruginous." — Curtis, 1. c. 

 Probably an immature state of one of the preceding species. 



Taken, I believe, in Norfolk. 



Family XII.— LIMNIIDiE. 



Antenna? rather long, nine or eleven-jointed, subfiliform, the last joints rather 

 larger, and forming a club : palpi short : body ovate, or subglobose, convex 

 above : head inflexed, deeply inserted in the thorax, which is more or less 

 quadrate and margined : legs elongate, alike ; tibia slender, not spinose : tarsi 

 elongate, four or five-jointed. 



Without professing to be an adept in the doctrine of affinity and 

 analogy, I consider that the insects of this family are far more 

 closely allied to the other Philhydrida, notwithstanding their dis- 

 crepancy of structure, than to the Byrrhidse or Histeridse, with
