NOTES. 235 



129. Eristicus is preoccupied by Wesmael, in the Iclineumonidae, 

 1845. 



130. Proctacantlius fulviventris Macquart. The length is said to 

 be four lines, an evident misprint for foiuieen, as appears from the 

 comparison to rKjivoitris (Loew /)( litt.K 



131. Asilus agrion. I have seen the original specimen in the 

 Senckenberg Miiscnm in Frankfort. It is nearly eaten up by Anthrcina^, 

 the abdomen being entirely gone, but it seems to be Pmctacaiitlm:^ Mil- 

 haiii; compare however the description with the specimens of the latter. 



132. Asilus is understood here in the wider sense, in order to in- 

 clude the species of former euthors which I could not place anywhere else. 



132. Asilus apicalis Bellardi. There is another Asilus apicalis 

 Wied.; see Erax. 



134. Both names, Mochtherus and Itamus are preoccupied by 

 Schmidt- Goebel in the Carabida, in 1846. (See Marschall's Nomenclator.) 



135. Asilus gracilis Wied. Very peculiar species, the type of which 

 still exists in Vienna. Schiner (Verb. Zool. Bot. Ges. 1866, p. 686), is 

 01 opinion, that it may provisionally be placed in the genus Mochtherus. 



135 a. Ommati'js. Mr. Bigot has an article about this genus, with 

 the list of all the described species, in the Annales Soc. Entom. 1875, 

 p. 237—248. 



136. Ommatius marginellus. Compare also Schiner, Verb. Zool. 

 Bot. Ges. 18B6, p. 682: „Very like 0. tihialis but differs in the bristles 

 of the mystax l)eing black (and not snow-white as in 0. tibialis) and 

 those on the hind femora being of the same color ;,and not altogether 

 or prevailingly yellow, as in 0. tibialis).''' 



137. Midaidae. Compare the essay on this family by Gcrstaecker 

 in the Stett. Entom. Zeitschr. 1868, p. 65 — 103 (with a plate): Syste- 

 matische Uebersicht der bis jetzt bekannt gewordenen Mydaiden. Earlier 

 monographs where given by Wiedemann and Westwood. 



138. About Mydas and Midas see in Gerstaecker, 1. c. With Wiede- 

 mann and others I prefer Midas. 



139. Midas audax. 0. Sacken, Bull. Buif. Soc. N. 11. 1874, p. 186. 

 ^. — Black, second abdominal segment red on the dorsal, as icell as on 

 the ventral side; head, thorax and first abdominal segment with whitish 

 hairs. Lcnrfth: 23 mm. Wiiif/: 18 mm. 



Very like 31. clacatus in its coloring, but easily distinguished by 

 its smaller size, comparatively broader head, more cylindrical shape cf 

 the abdomen, by the red color of the second segment, which does not 

 encroach anteriorly, on both sides, upon the first segment (as it does 

 in M. clavatus), which exists on the ventral as well as on the dorsal 

 side of the segment, and wMch is }iot interrupted on the dorsal side 

 by a more or less distinct black spot; finally, by the whitish pube- 

 scence on the bead, the thorax and the first abdominal segment. Head 

 black, broader than the thorax, clothed with soft, white hairs, mixed 

 with black ones; the wliite hair is especially apparent on the vertex 

 and the sides of the front, also as a small tuft on each side under the 

 antennae, near the orbit of the eye, and as a border round the clypeus.
