genus. The palpi are concealed in the oral opening, a character 

 which, according to the descriptions^ belongs rather to Anaba- 

 rhynchus. 



Thereva lateralis (Esch.) Wied. Auss. Zw. I, 231 (Manilla). 

 One 9; Ternate, 1875 (Beccari). 

 I saw this species named in the same way in Leiden. 



GYRTIDAE. 



There is a single specimen in the collection (Kapaor, N. Gui- 

 nea, April 1872; L. M. D'Alberlis). It has the venation of 

 Panops (comp. Macquart, Dipt. Exot. I, 2, Tab. 14, f, 2, Me- 

 sophysa^ which, as Erichson has shown, is the same as Panops), 

 as well as the general coloring of most of the species of that 

 genus, dark metalHc green body, with a fulvous pubescence on 

 the anterior part of the thorax, yellow legs, etc. It differs from 

 P. flavipes Latr. and Lamarckianus Westw. in the absence of 

 the minute supplemental cell at the end of the discal ; from 

 P. Baudini in the coloring of the body and legs. — The proboscis 

 of the specimen is broken off, as in a Panops it ought to reach 

 beyond the pectus. 



EMPIDAE. 



Hybos bicolor Walker, J. P. Lin. Soc. Ill, 91 (Aru). 

 Two d^, Islds. Aru, Wokan, 1873 {Beccavi). 

 The description agrees quite well. 



Hybos deficiens Walker, J. Pr. Lin. Soc. Ill, 129 (Key Isl.''^). 

 One specimen, Hatam, N. Guinea, June 1875 {Beccari). 

 The description agrees, but the pale hind tarsi are not men- 

 tioned in it. 



Hybos sp. One specimen, Hatam, N. Guin., 1875 {Beccavi). 

 Hybos sp. One specimen, Fly River, {L, M. D'Alhertis).
