]\Ir. ]'2. J'-'lffnul'jrs' S^'7io/isis of 



JJ. furniirrforiun, 15 oil. 



Scarcely luilf" the size of llic preceding-; Lend, lliorax 

 and scutelliiin ])ltcliy brown: elytra dull ochreons, densely 

 pubescent, sllglilly darker towards the apex outwardly; 

 membrane clear milky white; legs and antenna3 pitchy 

 brown, the tibia? paler. 



Length § line. 



Scotland; in nests o^ Formica rufa. 



TRIPIILErS. 



1. All the tibirc pale. Antennae entirely pale, in $ not 



iiicrassated .. .. .. .. .. .. mhudvs. 



2. Posterior tihiaj more or less piccous, 5 often black. 



Antenna; not entire!}' pule, in $ incrassated .. nif/cr. 



1. minntus, Linn, Fig. Dougl. & Scott, Brit. Hem. 



pi. xvii. fig. 3. 



Head and thorax black, shining ; the latter Avith a 

 strongly marked central transverse impression, deeply 

 punctured and Avrinkled posteriorly ; scuteilum black ; 

 elytra pale ochrcous, punctured and finely hairy, some- 

 times with a dark cloud across the a})ex ; membrane 

 dusky, paler at the base ; antenna3 and legs testaceous, 

 posterior thighs sometimes darker. 



Length 1 line. 



Common by sweeping, &c. 



2. nirjcr, Wolff. Fig. Wolff, Ic. Cim. fig. IGl. 

 Var. ohscurus, D. & S. 



Smaller and more parallel-sided than minntus, -with a 

 thicker, rather denser pubescence on the elytra. $ with 

 the elytra more or less pale or ])iceous, the apex widely 

 black ; j sometimes coloured as the $ , sometimes entirely 

 black; legs: 1st pair pale, 3rd and 4th more or less pitchy, 

 sometimes black. Antenna? in S much thickened, some- 

 times with second and apical joints pale ; j with thinner 

 antenna?. 



Length | line. 



Common by sweeping, especially on heaths. 



T. ohscurus, 1). & S., is, I believe, only a large pale 

 variety of this very variable species. ]\Ir. Douglas has 

 kindly lent me specimens for examination; but I can see 

 no definite structural character in them to justify a distinct 

 species being retained.
