500 MR. R. S. BAGNALL ON A COLLECTION OF 



Abdominal segments 7 and 8 practically subequaL Tube stout, 0"7 as long 

 as head, twice as long as 9tli segment, and but slightly longer than either 

 7 and 8 ; about 3 times as long as broad at base and twice as broad at base 

 as at apex. Terminal hairs about as long as tube, those on 9 a little longer. 



This species fits well into Section II.ii.B o£ my table on Neotropical 

 Dicaiothrips, wherein these two species were described, but is readily 

 separated from both kevicoUis and foveicollis by the short third antennal 

 joint and stout tube. 



Family E u P a t h i T H R i p i d ^, mihi. 



Head at least twice as long as wide ; dorsum compressed and subcarinate. 

 Eyes finely and closely facetted, prominent, contiguous, or nearly touching 

 anteriorly, almost completely surrounding ocelli ; ventrally well separated. 

 Cheeks with or without prominent spiniferous tubercles. Mouth-cone long 

 and pointed, reaching to beyond the base of the presternum. Antenna3 set 

 below vertex, on ventral surface : intermediate joints long and slender, 

 segments 3 to 5 (or 6) clavate, distally abruptly narrowed ; sense-cones very 

 long and slender. 



Cheeks •with prominent spiniferous tubercles. Anteuuge set higher on the ventral 

 surface, sense-cones longer, third joint shorter than or at most hue little 

 longer than 4. Fore-feunir in both sexes with a tooth uear apex within. 



Genus Eupathithrips, Bagn. 



Cheeks Avithout tubercles. Antennae set lower on the ventral surface ; sense- 

 cones shorter; third joint much longer than 4; anterior margin of pro- 

 thorax strongly emarginate. Fore-femur simple. . . . Genus Sedulothrips, nov. 



Genus Eupathithrips, Bagnall.

[Eupathithrips dentipes, Bagn. 1908. (PI. 48. fig. 10 ; PI. 49. fig. 5.) 

 This species is easily separated from silvestrii and affinis by its larger head, 

 the larger fore-legs, the distinctive shape of fore-femora (as in MJicehothrips, 

 Karny) which are without the minute spiniferous tubercles on the inner 

 margin, and the strong double series of teetii-like protuberances along the 

 inside margin of tibia. The abdomen is broader, and the segments 4-7 at 

 least have a white patch at each anterior angle. 



The prothorax is not so triangular in shape as shown in my original 

 figure, but I find it difficult to describe from the single dried specimen.]
