8 (9) Basal abdominal segment excessively densely scixlptwred right up to 



the actual apical margin, so as to be qiiite diill apically ; mesonotal 

 puncturation closer. 



8a (8b) Most or many of the flagellar joints of the antennae notably red 

 beneath alfkenella. 



8b (8a) Flagellar joints all dark, or at most with one or two apical ones more 

 or less reddish beneath moricella. 



9 (8) Basal abdominal segment along the apical margin less densely 



rugulose, so that in some aspects its apical portion appears shining ; 



mesonotal punctui-es more remote .falsifica n.n. 



(^ moricella $ , p. 75). 



The (^ oi A. fahifica in superficial appearance is extraordinarily 

 like those of A. ■minnhdoides, saunder sella, and alfkenella. This is 

 partly due to the pure white pubescence of the clypeus, while the hairs 

 of the upper part of the face and of the thorax are also very pale 

 or faintly yellowish. 



The very short 4th antennal joint distinguishes it structurally 

 from saundersella, and the rugulose surface of the two basal abdominal 

 segments from alfkenella, so that in my table it would be included 

 under the same heading as minutulasind minutuloides. Fresh examples 

 of the former are easily distinguished, superficially by the moi-e 

 bi-ownish -haired face, and structurally by the closer mesonotal punc- 

 turation. In falsifica the basal abdominal segment always bears 

 copious fine punctures amidst the rugulosity, and the following 

 segments are notably punctured. 



From minutuloides the duller surface of the mesonotum, which is 

 never at all polished, with its less conspicuous puncturation, will dis- 

 tinguish it ; the scutellum is t-ugulose and often dull all over, and 

 never has a highly polished area as in minuhfloides, while the clypeus 

 on its anterior portion is nuich duller from the rugulosity of the surface 

 between the punctures. 



It would appear that the tubercle of the labrum is of different 

 form from that which is normal in ininutuloidefi and minutula, but the 

 character is difiicult to see and may be subject to variation. 



I have examined a very fine freshly emerged series of about 40 

 examples of A. falsifica. Nearly all of these occurred in the same 

 spot and the only other of the group that was found with them was a 

 single J of the very distinct species, A. suhopaca Nyl.
