THE CANADIAN ENTOMOLOGIST. Ill 



specimens among Walker's types of M. speciosus. Finally I have seen 

 the types of Burmeister in the Halle Museum. The species is mentioned 

 by McLachlan in his review of AValker's paper ; as far as I know, it has 

 never been described. Fem., length of body, 50 m. m.; exp. al. 120 to 

 130 m.m. As I have no males before me, I give briefly the characters to 

 recognise the females : The front margin of prothorax notched in middle ; 

 with two transversal rolls, one before the front margin, the other before 

 the hind margin ; between them a flat, narrow, deepened saddle, perhaps 

 eight times broader than long ; a longitudinal black median band is only 

 a little enlarged on the saddle. P. spcciostcs has the front margin straight ; 

 the black median band fills the saddle on each side nearly to the side 

 margin ; the band is on the front roll triangularly dilated, but is wanting 

 on the hind roll. This character is very good to separate directly both 

 species. P. differ has the wings broader, more obtuse on tip, less spot- 

 ted ; front wings saffrony, with smaller ashy gray spots ; there are much 

 less numerous little spots around hind margin, and nearly none on the 

 disk ; ante-cubitals with black linear bands ; pterostigma straw color ; 

 hind wings paler, about hyaline, the brown bands less large, not connected, 

 the penultimate sometimes divided ; abdomen brown, darker below. 



The description of the appendages of the male is needed. 



1 have two females from Pniel Station, Damaraland, which I had 

 named P. sparsiis. As this name is now pre-occupied by a similar, per- 

 haps the same species, from Damara, by McLachlan, I refrain from giving 

 a description. It is intermediate between P. speciosus and P. Caffer, but 

 the black band of the prothorax is as on P. Caffer. 



8. Palpares pardalinus Burm. 



Burmeister, Vol. ii., p. 997, No. 20, describes the male from Orange 

 River, South Africa, collected by Dre'ge, In 1849 I bought the second 

 specimen from Ure'ge's collection, also a male, which I have compared 

 with Burmeister's type still present in the Halle Museum. Myrmelcon 

 pa?-daliniis Walk., p. 314, No. 26, a female from the Cape, is the same 

 species. This was doubted by McLachlan, Journ. Linn Soc, p. 275, and 

 for the species the name P. brachypterus proposed. Rambur's species is 

 different. In 1850, in Peters' Voyage, p. loi, I had placed P. pardalinus 

 together with the species of Pamexis. But I have corrected this in Stett, 

 Zeit., 1S60, p. 361, and 1866, p. 457.
