HAUPALIDiE. BADISTER. LICINUS. 73 



palpi rufous, with terminal joints piceous ; antennae pale ochraceous, with th6 

 basal joint rufous, the following more or less pitchy. In some specimens the 

 pale spot on the posterior half of the elytra is nearly obliterated. 



A common insect throughout the metropolitan district, abounding 

 durina: the winter months beneath the bark of felled trees. 



Sp. 3. suturalis. Plate V. f. 1. — Niger, elytris antich rufis apice nigris, 

 scutello suturd thorace pedibusque rufis. (Long. corp. 2^ Un.) 



Ba. suturalis mihi. — Steph. Catal. No. 99. 



Allied to the last, but the head is smaller, and the thorax more attenuated be- 

 hind, as in Ba. cephalotes : the head is black, not so wide as the thorax ; 

 the latter and the basal half of the elytra, the scutellum, suture, a narrow 

 margin to the elytra, and the legs, rufous ; the tarsi pitchy : abdomen be- 

 neath and head black : antennse reddish, with the basal joint clear rufous, the 

 two following dusky. 



I have seen one specimen only of this insect, which I believe I 

 captured near Hertford. It differs from the last in having a rufous 

 scutellum, by the dissimilar form of thorax, the colouring of the elytra 

 and tarsi. It has very much the aspect of Stenolophus vapora- 

 riorum. 



Genus XXVII. — Licinus, Latreille. 



Pa/pi moderately long; the last joint strongly securiform*: labrum narrow, 

 transverse, deeply notched; mandibles short, rounded, very obtuse, and 

 interiorly emarginate at the tip : mentuni very deeply notched, without a 

 central tooth: head rounded, anteriorly depressed and emarginate: eyes 

 slightly projecting : antennae filiform : thorax more or less rounded, quadrate, 

 or heart-shaped, anteriorly emarginate : elytra sinuated at the apex : wings 

 two, or more : males with the two anterior tarsi alone dilated ; the basal 

 joint trapeziform, the following pblong-oval. 



Licinus agrees with Badister in the simplicity of the notch of the 

 mentum, but differs by having the terminal joint of the palpi securi- 

 form : in this last character it resembles Panagseus and Epomis, but 

 the former distinguishes it from those genera. From the very obtuse 

 mandibles it is probable that the Licini are less carnivorous than 

 the other Adephaga: the species are rare in Britain, and delight in 

 dry hilly situations. 



Sp. 1. depressus. Aptents, ater, subopacus, thorace rotundato, punctulato, elytris 

 subtilissime punctato-striatis, basi subretusis. (Long. corp. 5 Un.)
