A female specimen from Gorontalo (Forstenj. 



18. Hermetia batjanensis, v. d. Wulp, 



H. batjanetisis , v. d. Wulp, Tijdschr. v. Ent. XXIII. 

 161. 8; — H. cerioides, Ost. Sack. Ann. Mus. Gen. XVI.

Three female specimens, one from South-Halmaheira 

 (Bernstein) , another from Morotai (Bernstein) and the third 

 from Andai (von Rosenberg). 



Two of these specimens differ from those which I des- 

 cribed in the » Tijdschrift", in having the four yellow spots 

 on the second abdominal segment confluent, so as to form 

 a pair of large lateral spots , which are a little contracted 

 in the middle. The underside of the antennae is partly 

 brownish-red and the tibiae are for the greater part of the 

 same color. 



It strikes me that Walker's description of Massicyta ce- 

 rioides (Proc. Linn. Soc. III. 78. 8) quite agrees with my 

 Hermetia batjanensis , if I do not mind to the generic cha- 

 racter: »abdomen obclavatum, subpetiolatum" (Proc. Linn. 

 Soc. I. 8), which very obviously is indicated in Prof. 



^otes from the Leyden museum, "Vol. "VII.
