GEOTRUPID.E. — TYPH(EUS. 179 



Gyllenhal states that the present insect is not found in Sweden, whereas the 

 last species is a native of that country. 



I believe all my specimens were taken in Norfolk. 



+ Sp. 3. quadridens. Ferrugineus, capitis cornu elevato simplici, thorace an- 



tice quadridentato. (Long. corp. 6 lin.) 

 Sc. quadridens. Fabricius. — Bo. quadridens. Steph. Catal. 106. No. 1103. 



Much larger than Bo. mobilicornis ; ferruginous ; male with a short immoveable 

 horn on the clypeus; thorax with four, nearly equidistant, obtuse teeth near 

 the anterior margin ; elytra punctate-striated. Female with a slightly ele- 

 vated line on the head, and another more obsolete near the anterior margin 

 of the thorax. 



The only recorded indigenous examples of this species were 

 taken during a flood on the marshes between Peterborough and 

 Wisbeach, in the summer of 1807, by Mr. W. Skrimshire, who 

 states, in the Entomological Transactions, p. 317, that lie captured 

 a pair, male and female. 



Genus CXCIV. — Typhceus, Leach. 



Antenna rather slender, the basal joint elongate and robust, slightly pilose; the 

 second short, globose; the three following of nearly equal length, slightly 

 elongate ; the three next short, transverse, the remainder abruptly forming 

 an ovate trilamellate club. Palpi maxillary with the terminal joint rather 

 longer than the third, slightly attenuated at each end: head triangular: 

 clypeus rhomboidal, incurved: thorax large, convex, produced anteriorly 

 into horns or tubercles : elytra oval, convex : body robust, ovate : legs stout : 

 femora simple : tibice curved, serrated externally : tarsi with the basal and 

 terminal joints of equal length, elongate. 



Typhoeus was established as a genus by Dr. Leach, in 1812, in 

 the Edinburgh Encyclopaedia, but within these few years Fischer 

 also proposed detaching it from Geotrupes, by the name Cerophyus, 

 which has been adopted by Latreille, in the new edition of the 

 Regne Animal, regardless of the priority of Dr. Leach's claim ; in 

 justness, however, to my friend, I shall retain his original appella- 

 tion : — the cornuted thorax, elongate fourth joint of the antennae, 

 and basal joint of the tarsi, will sufficiently enable any one to detect 

 the only indigenous species, which usually frequents sandy or 

 gravelly wastes and heaths
