MYRMICA. 127 



Mas : nigro-fuscus nitidus sparse tenuiter flavido-pilosulus, mandibularum 

 apicibus et tarsis testaceo-pallescentibus, antennis fusco-rufescentibus ; 

 scapo longitudine quintae partis totius antennae ; pedibus longe pilosis. 



cJ. Long. 2J lin. Similis niari M. laevinodis, antennis vero longitudine 

 tantum flagelli in eadeni specie, scapo quiiitam solum efficiente partem 

 totius antennae, pedibus longe flavido-pilosis. Mandibulae apice sordide 

 pallidae. Antennae obscure rufescentes, longius tenuiusque pilosae quam 

 feniinae et operariae ; scapus subcylindricus, longitudine tantum trium articu- 

 lorum insequentium, crassitudinem articuli ultimi superans ; pedicellus suborbi- 

 culatus crassior quam ullus septem articulorum sequentium, qui sunt longe 

 verticillatim pilosi ; 9, 10 et 11 suborbiculati crassiores ; ultimus subconicus 

 longitudine fere 10 et 11 (simul sumtorum), sed ejusdem ad basin crassitudinis. 

 Est igitur flagellum ut in feminis fere hujus Generis formatum, at articulis 

 12. Alae minus albescentes quam in $. Pedes longe undique pilosi, pilis 

 his cinerascentibus in tarsis fere longioribus. Anus obsolete pallescens." 



Habitat. 



Myrmica scabrinodis is found in North and Central Europe, 

 Siberia, and Turkestan, and varieties 31 occur in the North and 

 North-eastern States of America, in Alaska and British Columbia. 



It is widely distributed in the British Isles, having been recorded 

 as far north as South Aberdeen and Westerness in Scotland, whence 

 I have records from Dumfries, Ayr, Renfrew, Haddington, Edin- 

 burgh, Linlithgow, Fife, Kinross, Stirling, South and Mid Perth, 

 Dumbarton, and the Mid Ebudes ; and in Ireland from Antrim, 

 Down, Armagh, Tyrone, Donegal, Dublin, Wicklow, Wexford, 

 Carlow, Westmeath, West Mayo, East Galway, Waterford, South 

 Cork, and Kerry. I have no records in England from South Wilts, 

 Cambridge, Bedford, Hunts, East Gloucester, Monmouth, Salop, 

 South-east, South-west and North-west Yorks ; and in Wales from 

 Brecon, Cardigan, Montgomery, Merioneth and Flint. 



Myrmica scabrinodis nests under stones, on heaths and banks ; it 

 does not readily dwell near houses, and on the whole prefers dry 

 sandy places. Indeed Forel 9 states it does not occur in woods nor 

 damp places, and never nests in tree trunks, but is to be found on 

 the plains at the edges of woods and roads in dry places, exposed 

 to the south, Andre 12 says it is uniformly established in dry places, 

 Wasmann 17 gives dry sandy soil on the borders of pine woods, etc., 

 and Escherich 25 dry places. 



On the other hand Bouskell sent me several colonies from 

 Kerry which he had found in the bogs, being all but covered with 

 water 34 , and I found a colony under a stone in a marsh at Studland 

 and several others in clumps of very damp sphagnum in the bogs 

 in the New Forest. 



It is stated not to extend to as high an altitude as lobicornis 12 , 

 nor to reach the region of the pines 9 . Hull has sent me scabrinodis 

 from West Allendale taken at a height of 1000 ft., and though this
