 I have taken males and winged females in the nests in July and 



Antenn.e of M. scabkinodis.

August, and at large in September and October. I"- have often found 

 workers in nests of Formica mwininea. Angus'"' records specimens 

 found in the stomach of a green Woodpecker {Picua ririilis) shot in 

 January in N. Wales. DoUman picked up a dead ergatandromorph at 

 Ditchling, which he kindly presented to me. !'•* have recorded it, but 

 as it has never been described, I have now drawn up a description : — 



Approximately lateral ergatandromorph, right half of body almost entirely 

 that of a 5 , the left being that of a normal <? (the left half being blackish and 

 the right reddish-yellow). Eight half of head rugousiy striate, larger than left, eye 

 smaller ; right antenna yellow, club three-jointed ; scape with strong lateral tooth 

 at the bend ; right half of thorax yellow ; epinotum with a strong spine ; right 

 half of petiole and post-petiole yellow, rugose and punctured ; right half of gaster 

 light fuscous-yellow ; legs on right side yellow, typical 5 . Left side of head 

 blackish, punctured, not rugousiy striate; eye larger; median and left ocelli 

 present; antenna fuscous with four-jointed club; left half of thorax blackish; 

 epinotum not armed with a spine ; petiole and post-petiole fuscous-black, smooth ; 

 the greater part of the left half of the gaster has been eaten away, but what 

 remains is of a darker fuscous colour than the right. Legs on left side fuscous, 

 typical cT ; wings typical d . 



In this specimen the scape of the left antenna ( J ) is longer than 

 in typical scabrinodis ^ , and the tooth on the right antenna ( ^ ), is 

 large. It is therefore near to the var. sahnletl, Meinert. 



Wasmann''^ describes an ergatandromorph in which the left half is 

 ^ and the right 3 .
