NOTES. 229 



from Mexico. They look t xccedingly like cof^talia. Of T. cof!talis, the 

 types in Wiedemann's collection are very poor specimens, and for this 

 reason, probably, his description is unrecognizable. 



89. Tabanus fulvescens Walker. I have seen Walker's type in the 

 Brit. Mus.; it is T. hicolor Wied. What I dv^scribed as T. fiilre.<<ccns 

 is very probably only a variety of* T. hicolor, with gray, instead of 

 yellowish pleurae. A similar variety occurs in T. fulruhis. 



90. Tabanus Craverii. May possibly be an Atyhtus. The typical 

 specimens, females, loolved very much that way. 



91. ]Mr. Loew (/» liii.) proposes to divide in the Leptidae two sections: 

 I. Psammorycterina, without facial swelling and with a strong 



spur on the front tibiae; genera; 1. Flicncus, as the typical 

 genus, closely allied to: 2, Vsammorycter (Syn. Vermileo); 

 3. Triptotn'cha. 

 II. Leptina, with a facial swelling, but without spur on the front 

 tibiae; all the other genera. 

 About Leptidae compare also Fraacnfdd, Verb. Zool. Bot. Ges. 

 1867, p. 495. 



92. Leptis Servillei Guerin. I suspect this is nothing but Chr. 

 on?«fa Say. But the femora are said to be brown? The figure however 

 does not show it. 



93. Atherix filia Walker; is either punciipennis Say, or phimhca Say. 



94. Leptis cinerea Bell according to the description, cannot well 

 belong to Leptis; compare antennae, shape of anal cell etc. [Loew, in 

 litt.]. The type in Mr. Bellardi's collection is, unfortunately, nearly 

 destroyed only the thorax and wings are left. 



95. Spania edtta; the specimen in the Brit. Mus. seems to be a 

 real Spania, that is a Leptid with a stout, styliform arista. 



96. G-lutops. I am uncertain about the position of this extra- 

 ordinary genus, but prefer this place to any other. 



97. H. Loew's Monograph: Ueber die Europaischen Raubfliegen 

 (Diptera Asilica), in the Linn. Ent Vol. II, 111, IV: Suppl. in Vol. V, 

 1847 — 1851, laid the foundation to the systematic distribution ot this 

 family. This work was supplemented by him in numerous later publi- 

 cations, especially in the: Bemerkungen iiber die Familie der Asiliden, 

 Berlin 1851, and Die Diptern-Fauna Siidafrica's, Berlin 1860. About 

 the exotic Asilidae, the following important papers by Dr. E,. Schiner 

 may be consulted : 



1. Die WiedLmannn'schen Asiliden (in the Verb. Zool. Bot. Ges. 

 1866, p. 649—722; Nachtrag, p. 845—848). The usefulness of 

 this paper is somewhat impaired in consequence of the misappre- 

 hension under which it was written, about the distribution of 

 Wiedemaim tj^ies between the so-called Wiedemann's and the 

 Winthem's collections, now both in the Vienna Museum. I have 

 explained the whole matter in the preface to this volume. Some 

 curious mistakes have arisen in consequence, as for instance, in 

 the case oi Lrax aestuanft (see my note 125). But Dr. Schiner's 

 paper is nevertheless rendered invaluable by a survey of all the
