234 NOTES. 



and never described any insects from Cuba. In the Diptera of the 

 Novara Expedition, however, Schiner quotes "Wiedemann's and Mac- 

 quart's descriptions as synonymical. I follow Loew, in lift, and call 

 the Cuban species M. Macquartii. Jaennicke has the same remark 

 about the distinctness of the two species (Neue Ex. Dipt. p. 54). 



121. There is another Trupanea (Promachus) apivora Walk., Trans. 

 Ent. Soc. N. S. V, p. 276, from Burmah, which has the same propens- 

 ity for destroying bees. Mr. Walker's name having the priority, I have 

 named Dr. Fitch's species P. Fitchii in the M. C Z. collection. 



122. Promachus quadratus. Observe the misprint in Wiedemann's 

 diagnosis: (J for ; correctly given in his Dipt. exot. 



123. Promachus fuscipennis. The identity of Macquart's and Bellardi's 

 species seems doubtful. 



124. Promaclius quadratus Bell. If this species does not turn out 

 to be a synonym of some other, the name will have to be changed, on 

 account of P. guadratus Wied. 



125. Erax aestuans. I have seen Wiedemann's type in the Win- 

 them collection ; it is the Erax aestuans of the Mus. Coinp. Zool. Schi- 

 ner's statements (Verb. Zool. Bot Ges. 1866, p. 686) are based upon a 

 misapprehension of the true type of Wiedemann, a misapprehension the. 

 source of which has been explained by me in the preface to this volume. 

 But although the question of Asilus aestnans Wiedemann is thus settled, 

 the identity of this species with As Hits aestuans of Linne and Fabricius 

 may still be called in doubt, as the descriptions of both authors speak 

 of three white segments on the abdomen of the male, while A. nest nans 

 Wied. has only two. Harris's Ins. Inj. to Veget. 3<i edit., Tab. I, f. 4, 

 shows only t/co stripes. Compare also the note 128. 



126. Erax ambiguus, interruptus, argyrogaster, maculatus. Macquarf s 

 types of these species, which I have seen in the Museum in Lille and 

 in Mr. Bigot's collection, look very much alike. However, I did not 

 compare them with the descriptions ; the latter, which I have read since, 

 show that arr/yrogaster has a large male hypopygium, amliguns a re- 

 markably small one for an Erax. E. macidattts, judging from the figure, 

 has likewise a large hypopygium. For the species which I have seen 

 from Texas I preferred the name of am l>i<jn us, as the most certain; the 

 hypopygium of the male, in this species, is remarkably small for an Erax. 

 I admit at the same time that the female of this species looks exactly 

 like the figure of the female of E. maculatus in Macq. D. Exot. I, 2 ; 

 Tab. IX, f, 6. Schiner (Verb. Zool. Bot. Ges. 1867, p. 393) compares 

 E. maculatus to its next relative, E striola, the specimens of both being 

 from Brazil. 



127. Asilus apicalis. Wiedemann's type, a female, was in his 

 collection, but is no more in it. See Schiner, 1. c. -- Walker, List, etc. 

 VII, p. 619, puts this species in the genus Erax, where indeed it 

 may belong. 



128. Erax lascivus. All that Schiner (Verb. Zool. Bot. Ges. ISfifi, 

 p. 686, Nr. 63) says about this species, results from the misapprehension 

 under which he was laboring. See my note 125.
