98 Mids G. Elcardo on the Genus Ilaetnatopota 



One female from Glen Avon^ S. Banffsliire {fV. R. O.- 

 Grant), 93. 95. 



The male of this spceies may easily be distinguishctl by 

 the wholly black eolour of the antennae and by tlie very thick 

 first joint. 



The female is less easily distin^jnishcd from that of 

 H. phwialis, but Strobl, in'Mittheil. Ver. Steierm. 1892, 

 xviii, (1893), recognizes it by the extraoi'dinarily thick 

 first joint, which is short, stout, and not constricted near the 

 tip ; only at its base is it obscured by grey tomentum ; the 

 shining black band above the antennae is narrower and not 

 ])roduced above in the centre ; the third joint of the antennae 

 is only red at the base. In H.pluvialis the first joint is much 

 slenderer, covered Avith grey tomentum to the middle and 

 strongly constricted before the tip ; the red colour on the 

 third joint is more extended, the black band broader, 

 produced in the centre as a triangle. 



The four males collected by me form part of a scries of 

 two dozen or so caught in one Aveck, resting on the highest 

 and sunniest parts of a stone wall round an unoccupied 

 farmyard ; no females were to be seen. I was not successful 

 in discovering their breeding-place. 



Nearctic Reyion. 



There are only two species known in N. America, both 

 said to be fairly common. There was a specimen in the 

 British Museum Collection labelled " N. America" and 

 ])laeed under H. pvnctidata ; it is apparently a specimen of 

 //. varieyata, and certainly does not agree with the description 

 of either of the N. -American species ; the locality-label is 

 probably incorrect.
