Idolothripidse. 



Genus Mecynothrips, Bagnall. 



Mecynothrips simplex, sp. n. 



Length about 9*0 mm. 



Superficially this form closely resembles M, wallacet, 

 Bagn., and is similar in its type of coloration. The antennpn 

 are slightly stronger and have not tlie prominent long hair at 

 the outer apical margin of each of the intermediate segments. 

 The lateral cephalic setae spring from very minute warts and 

 are not conspicuous. 



The prothorax is simple, with a moderately long forwardly 

 directed seta set on a slight protuberance at each anterior 

 angle. 1'he fore femur is more strongly crassate and appa- 

 rently has not the strong tooth near the apical third within 

 seen in il7. wallacei, but it appears to have a minute tooth at 

 the apex within. The hind and intermediate legs are rela- 

 tively shorter and stouter. Tiie wings reach to the fifth 

 abdominal segment. 



The tube is longer than in ivallacei, not quite three times 

 as long as the penultimate segment and nearly as long as the 

 eighth and ninth segments together.
