TACHYPORID.E. AUTALIA. 101 



Genus CCCCLXXXV.— Autalia, Leach MSS. 



Antennw sensibly thickening from the base to the apex, the basal joint largest, 

 the two following rather long and subclavate, the remainder turbinate- 

 tiansverse, with the apical one ovate. Palpi very short, 4-jointed, the 

 penultimate jomt large, somewhat obconic, the terminal one very slender, 

 setiform: labrum minute: head exserted, globose-orbiculate ; neck very 

 slender: thorax subglobose, a little narrowed in front, plicate behind: 

 scuiellum none : eli/tra plicate at the base, about two-thirds as long as the 

 abdomen; the latter linear, recurved: legs moderate ; femora lanceolate; 

 tibice villose, unarmed; tarsi subsetaceous, 5-jointed. 



The insects of this genus are evidently in close alliance with those 

 of the preceding family, from which they may be immediately recog- 

 nized by the dissimilarity in the length and structure of the maxillary 

 palpi, as weU as by their general habit, and by possessing 5-jointed 

 tarsi, with two claws at their apex. As in the Pselaphidae, the elytra 

 are impressed at the base, which gives that part the appearance of 

 being folded. The head is very distinct, and united to the thorax 

 by a strangulation ; the latter is more or less cordate, and has gene- 

 rally one or more impressed furrows upon it. The species are found 

 at the roots of grass and in boleti in damp places, during the winter 

 and spring.

St. impressus. Olivier. — Au. impressa. Steph. Catal. 259. No. 2575. 



Reddish, shining: head fuscous: thorax globose, very glovssy, with three abbre- 

 viated long\tudma\ furrows in the middle, one of them at the apex and two 

 at the base; adjoining the two last are two foveola; : elytra fuscous, with 

 four abbreviated furrows at the base : abdomen obtuse, rufous, with a 

 black belt towards the apex : legs rufo-testaceous : antennae reddish, with 

 the base paler. 



Found not uncommonly in the neighbourhood of London ; also in 

 Norfolk and Suffolk, and in Devonshire. " In decaying fungi, not 

 uncommon (near Swansea)." — L. W. Dillwyn^ Esq. 



Sp. 2. plicata. Rufa, capiie ahdominisque cingulo, nigris, thorace elytrisque 



antice plicatis. (Long. corp. 1^ lin.) 

 Al. plicata. Kirby MSS.— Am. plicata. Steph. Catal. 259. No. 2576. 



Rnfous, shining, fmelij pubescent: head suborbiculatc, larger than the thorax.
