86 INSECUTOR INSCITI^ MENSTRUUS 



sleeve, but they escaped capture. She was wielding the bottle 

 at the time and hesitated through surprise. She "could hardly 

 believe her eyes" as she said, for we were not expecting 

 diantaeus. 



Aedes intrudens Dyar. 



Throughout the forest in dark woods, but not quite so par- 

 ticular as to location as diantaeus. The hybrids between this 

 and lazarensis perhaps deserve detailed mention. In the male 

 hypopygium the apical lobe is strongly hairy outwardly as in 

 lazarensis, not weakly so inwardly as in intrudens. Apical 

 hair-tuft of intrudens wanting, though the inner margin of the 

 whole lobe is unusually hairy. Basal lobe with the two spines 

 on a pedicel of intrudens, but they are lengthened, flattened 

 and irregular. The spine on one side is large, but there is some 

 rugosity between these spines suggestive of the lazarensis lobe. 

 Claspette angled and with basal hairy part as in intrudens, but 

 the angulation is less sharp, there is no prominence or stout 

 seta. Filament broader than in lazarensis, longer than in 

 intrudens, with only a trace of the internal vacuolations of 

 intrudens. 



Aedes pullatus Coquillett. 



Rather rare, but occurring throughout the forest. Much 

 variation was noted, and it is supposed that some of the speci- 

 mens are hybrids with lazarensis and others with cataphylla, but 

 no males of these mixed forms were obtained. 



Aedes trichurus Dyar. 



This large and interesting species was a feature of the forest 

 on the west of the divide, but no specimens came through to 

 the east, even high in the range. I am inclined to think that this 

 is specifically distinct from the eastern cinereoboreaUs F. & Y., 

 but unfortunately the male remains unknown. 



Aedes cinereus Meigen. 



A male was taken near the town of Whitefish, and the 

 species doubtless exists sparingly throughout the forest.
