Allied to H. elongatula, but smaller and more slender, 

 with broader head, and stouter antennae ; brighter 

 coloured, and with the thorax more narrowed behind, &c. 

 Antennas yellow, rather longer than the head and thorax, 

 a little thickened towards the apex ; joints one to three 

 moderately long, three scarcely so long as two, four to 

 ten each a little stouter than the preceding one, four and 

 five rather slender, six about as long as broad, seven to 

 ten each broader than long; eleventh joint rounded. 

 Mandibles and palpi yellow. Head rather short and 

 broad, but little narrower than the thorax, finely and in- 

 distinctly punctured. The thorax is scarcely narrower 

 than the elytra, gently but distinctly narrowed behind, 

 about one-fourth broader than long, finely and closely 

 punctured, with an indistinct longitudinal channel. Ely- 

 tra a third longer than the thorax, of a brownish or 

 yellowish colour, finely and pretty densely punctured. 

 The abdomen is black, with the extremity yellow ; seg- 

 ments two to four finely and moderately closely punc- 

 tured, fifth segment sparingly punctured, sixth almost 

 impunctate. Legs clear yellow. 



In the male, the ventral plate of the seventh segment 

 of the abdomen is produced considerably beyond the 

 upper plate ; its sides are parallel, so that it is not nar- 

 rowed towards the apex, which is truncate, with the 

 angles rounded. 



In marshy places in England and Scotland, but not 

 common. 



52. Homalota fallaciosa. 



Nigro-fusca, antennis ore anoque obscure testaceis, 

 pedibus testaceis, elytris fuscis ; capite thorace angustiore,
