British Species of Homalota. 99 



broad, 6-8 about as long as broad, 9 and 10 a little trans- 

 verse, lltli ovate, acuminate, about twice as long as the 

 tenth. Palpi testaceous. Head a little narrower than 

 the thorax, thickly and finely punctured, with an obsolete 

 fovea in front. Thorax narrower than the elytra, its 

 length abovit equal to its breadth, the sides a little rounded 

 in front, then slightly narrowed towards the base, densely 

 and finely punctured, with a not very distinct channel. 

 Elytra fuscous, scarcely longer than the thorax, not so 

 long as broad, finely and tolerably densely punctured, 

 the punctuation not so dense as on the thorax. Abdomen 

 Avith segments 2-5 thickly and finely punctured, 6th 

 nearly impunctate. Legs yellow. 



The male has an elongate raised tubercle on the upper 

 side of the sixth abdominal segment, which reaches nearly 

 to the apex, and the hind margin of the seventh segment 

 is armed with four indistinct teeth. 



Not common. Nithsdale, Rannoch, Edinburgh, Brigh- 

 ton. The male is much rarer than the female. 



I have a small variety found in Nithsdale, in which the 

 elytra are not quite so long as the thorax. 



Ohs. — In the Brit. Mas. are four specimens of H. pa- 

 vens sent by Dr. Kraatz ; these agree with the examples 

 just described. It is, I believe, the H. sulcifrons of Mr. 

 Waterhouse's Catalogue, but I cannot say with certainty 

 whether it is Stephens^ Aleochara sulcifrons. His name 

 would appear to point rather to H. insecta.
