ADDITIONS AND CORRECTIONS. 



I. To the list of Authorities add : 



COSTA, Achille. lu Auuuario del Museo Zool. Uuiv. di Napoli, II, p. 

 151, 1864. 



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

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

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

 S. foenoides, Westm. 



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, antennis, peristomate, thoracis vitta 

 utrinque antice T-fortni maculisqne duabus ad scutelli angulos baseos, 

 pedihus anterioribus basi excepta, et posticorurn apice feiiiorum et tibia- 

 rum tarsoruinque articulo primo flavis ; metatuorace flavo, maculis quatuor 

 rectangulis nigris ; abdominis segmentis 1 4 infra pallidis ; alis ciuereo- 

 hyalinis, veuis fuscis. Long. mill. 22. 



II. Dates of the first publication of genera. In prepar- 

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

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



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



Simulium, Beris, Pipunculus, Scenopinus, Ochthera, Onrithomyia, Afelo- 

 pkngus, Nycteribia appeared in Latreille, Hist. N. des Crust, et des Ins. 

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



Asynduliun, Rhi/phus, Hermetia, Psazus, Paragns, Milesia, Erislalis, Ploas, 

 Ocyptera, Phasiti, Osciiiis, Sepedon, Ttphritis. Lau.rania appeared in the 

 Dictionn. d'Hist. Natur., 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.
