the european and north-american species. The fourth posterior 

 and the anal cells are closed at a greater distance from the 

 margin of the wing than in the european S. marginata; and the 

 tip of the fourth p. c. is 7iot connected by a vein with the 

 margin ; the second vein, issuing from the discal cell is inter- 

 rupted before reaching the margin , the same as in S. margi- 

 nata. I have not noticed in the Brit. Mus. the Solva hybotoides 

 Wk. 1. c. VI, 5. (Gilolo). 



Suhula Jlavipes DoL, 3^" Bijdr. 13, I would have taken for the 

 same as S. inamoena , if the antennae ''were not said to be 

 hrown. 



Rhachicerus zonatus n. sp. 9 • Antennae and legs rufous, ab- 

 domen black, with an obscure reddish crossband at the base of 

 the second segment. Long. corp. 12-13 mm. (without the ovi- 

 positor). 



Palpi and antennae rufous, as well as the part of the front 

 immediately above the root of the antennae ; antennae with 

 30-31 joints ; the joints of the llagellum , except the last, are 

 provided on the underside with branches, forming a dense comb ; 

 front and vertex black, shining ; occiput dark reddish. Thoracic 

 dorsum brownish-yellow ; humeral callosities paler yeUow ; behind 

 each, an interrupted black stripe, not reaching the root of the 

 wing ; two ill-defined black, parallel stripes , almost coalescent 

 on their inner side, occupy the middle of the dorsum and 

 nearly reach the scutellum ; the latter yellowish-red. Pleurae : 

 the portion between root of wings and front coxae black, shi- 

 ning ; the rest reddish-brown ; metathorax yellowish-brown , 

 brownish in the middle. Halteres : stem yellowish-brown ; knob 

 brown. Abdomen black, shining ; at the base of the second seg-

 root of hind coxae brown ; extreme tip of hind tibiae and two 

 or three last joints of tarsi, brownish. Wings subhyaline, with a 

 brownish cloud between the costa and the proximal end of the 

 discal cell ; the latter half of the wings , beyond the central 

 crossveins is sHghtly tinged with grayish.
