British Species of Homalota, 173 



thorax, punctured closely and finely, but more distinctly 

 than the thorax. Abdomen with segments two to four 

 finely but distinctly and moderately closely punctured, 

 five and six very sparingly punctured, apex indistinctly 

 paler. Legs fusco-testaceous. 



In the male, the channel on the head is longer and 

 more distinct than in the female, and the abdomen has 

 the seventh segment underneath more produced and 

 narrower than in the female. 



This species appears to be not common ; I have found 

 it only at Hammersmith Marshes, and in a marshy place 

 near Thornhill. 



Ohs. — Compared with typical H. analis, H. gemina is 

 larger and darker coloured, with longer and stouter an- 

 tennae, differently shaped head, and more sparingly punc- 

 tured abdomen. Two specimens of H. gemina sent by 

 Kraatz to the British Museum agree with my British ones. 



67. Homalota curtipennis. 



Nigro-fusca, antennis elytrisque fuscis, illarum basi 

 pedibusque obscure testaceis ; capite thorace evidenter 

 angustiore, antice angustato ; thorace transverse, basi 

 plus minusve impresso ; elytris hoc nonnihil longioribus ; 

 abdomine segmentis 2-4 sat crebre punctatis, 5° par- 

 cius punctate, 6° fere laevigato. Long. 1 lin. 



Mas ; fronte plana, capite subtiliter canaliculate, ab- 

 domine segmento 7° ventrali paulo elongato. 



Fern. ; fronte convexiuscula. 



Atheta hreviceps, Th. Sk. Col. ix. 273 (forte) . 



Allied to H. gemina, but with shorter antennse and 

 elytra. The antennae are quite as long as the head and 

 thorax, obscure testaceous, paler at the base, moderately 

 stout, distinctly thickened towards the apex ; joint three 

 not quite so long as two, four to ten differing but little 

 in length, but each a little broader than its predecessor, 

 four to six each about as long as broad, seven to ten 

 broader than long; eleventh joint moderately long, nearly 

 twice as long as its predecessor. Head distinctly nar- 

 rower than the thorax, considerably broader behind the 

 eyes, and narrow in front, finely and indistinctly punc- 

 tured, flat above and indistinctly channelled in the male,
