210 THE CANADIAN ENTOMOLOGIST. 



base of the hind wings of the male is a small white free knob, homologous 

 to the larger and darker knob of Palpares and Acanthaclisis. The larva 

 of one species is known ; it differs from all others and was described by 

 me as perhaps belonging to Acanthaclisis congener. 



Mr. McLachlan has described the female of a species from Turkestan 

 as a new genus, Maracanda atnoena, which has the same characters as 

 the N. American species, with one series of areoles in the costal space of 

 the front wings. The only exception is that the apical joint of the labial 

 palpi are said to be very much dilated, what is not to be found in the N. 

 American species. I do not know M. amoena, but I should think that its 

 difference from M. imbecillus Stein., from Greece, should be proved. M. 

 conspurcatus Kolenati, from the same locality with M. amoena., can not 

 belong to Creagris plumbeus, where it is quoted by Brauer and McLach- 

 lan, as its size is by far too small and only very little larger than amoena. 

 I can not compare the two Australian species, said to have no spurs. 



I possess a couple of M. imbecillus Stein (Berl. Ent. Zeit., vii., p. 

 421) from Montenegro, Europe, which agrees entirely with il/. amoena, 

 and can not be identified with any other described species. The legs have 

 no spurs,* contrary to Stein's description, but bristles, yellowish-brown, 

 straight, half shorter than the basal joint. After this rather long preamble, 

 I come to the question if perhaps some Myrmeleon, just as among Phry- 

 ganids some Limnophilids have spurs which can be wanting or 

 aborted, at least on the fore legs. 



There are a number of N. American Myrmeleon, M. longicatidns, M. 

 ferus, M. nebulosics and others, which nobody would separate from M. 

 coHspersus, except by the presence of spurs. Some have two series of 

 areoles in the costal space, and some only one series, as in Maracanda. 

 Nevertheless none of the seventeen Af. conspersa before me has a spur, 

 and none of the six Af. longicatidus and the six 7I/. contaminatus lacks 

 spurs. Therefore I have the species without spurs described as belonging 

 to Afaracanda, and propose provisionally for the other a new genus, 

 Brachynemurus. 



Afaracanda, McLachlan. 



This new genus is described in A. Fedtschenko's Voyage in Turkestan, 

 vol. ii., 5, Moscow, 1875. The largest part is in the Russian language. 

 As the N. American species without spurs at the tips of. the tibiae must 



* Mr. H. J. Kolbe, A.ssi.stant of the Berlin Museum, has kindly conqiared Stein's 

 type and confirms my statement.
