Hab. S. AUSTRALIA, Adelaide, Mount Lofty Range, 1 ?

 themum, Aug. 28th, 1914 {E. B. Poulton). Reg. 41 and 43. 



Haplothrips melanoceratus", sp. n. 



This species agrees in almost every respect with H. ro- 

 bustus, sp. n., but may be sharply distinguished by the fact 

 that the antennal segments 1-8 are all entirely of a uniform

 is more than twice as broad as long. The unique example 

 appears to be slightly teneral, and, excepting for the antennas, 

 is noticeably lighter in colour.
