ADDITIONS AND CORRECTIONS. 



I. To the list of Authorities add : — 



Costa, Achille. — lu Aunuario del Museo Zoo). Uuiv. di Napoli, II, p, 

 151, 18(J4. 



N. sp. Systropus Sallei and S. funereus, both without indication of 

 locality, but both evidently Mexican ; the first, a species very frequently 

 met with in collections (also iu the M. C. Z.); the second, a synonym of 

 S. foenoidea, Westra. 



I discovered these descriptions accidentally, in looking over Mr. Bigot's 

 library. The diagnosis of *S. Sallei, which I reproduce, will be fully 

 sufficient for its recognition. 



Systropus Sallei. — Niger, autennis, peristomate, thoracis vitta 

 utrinque antice T-fornii maculisque duabus ad sciitelli angulos baseos, 

 pedibus anterioribus basi excepta, et posticorum apice feuiorum et tibia- 

 rum tarsorunique articuloprimo flavis ; metatuorace flavo, maculis quatuor 

 rectangulis nigris ; abdominis segmeiitis 1 — 4 infra pallidis ; alis cinereo- 

 hyalinis, venis fuscis. — Long. mill. 22. 



II. Dates of tlie first pii1)lication of genera.— In prepar- 

 ing this Catalogue for the press I did not have Latreille's works at hand, 

 1 had to rely on Schiner, but have discovered the following errors since : — 



Phora was published in Latreille, Precis, etc., 1796. 



Sunulium, Beris, Pipiincuhts, Scenopinux, Ochthera, Onnthomyia, Melo- 

 phagus, Ni/ctpribia appeared in Latreille, Hist. N. des Crust, et des Ins. 

 Vol. Ill, 1802 (and not Vol. XIV, 1804, as Dr. Schiner has it). 



Afti/ndulum, Rhiiphn.^, Ilennetia, Psnzus, Parac/us, Mllesia, Erislalh, Ploax, 

 Oci/ptera, Phasia, Oscinis, Sppedon, Tfphritix, Lmtrrniia appeared in the 

 Dictionn. d'Hist. Natnr., Deterville, Vol. XXIV, 1804, and also in Hist. 

 Nat. des Crust, et des Ins., Vol. XIV, in the same years 1804. The pub- 

 lication in the Dictionnaire is generally quoted as the earlier one ; it would 

 be better, perhaps, to quote both.
