KNOWLEDGE OF THE NEOTROPICAL THYSANOPTERA. 375 



DiCAiOTHRiPS FOVEicoLLis {Bagnall). (PL 51. figs. 1 & 2 ; PL 52. 

 figs. 1 & 2.) 



Idolothrips foveicoIUs, Bagnall, Traus. Nat. Hist. Soc. of Northumberland, Durham, and 

 Newcastle-upon-Tyne, n. s. iii. p. 214, pi. 7. fig. 12 (1908). 



I have already stated that this is a compound species as regards the male, 

 the second species being herein separated under the name of Championi. 



S . The true foveicoUis has the eighth abdominal segment distinctlj^ shorter 

 than the seventh, and the tube, which is slenderer than in Championi, is con- 

 siderably longer than either the seventh or eighth segment. The post-ocular 

 spines are apparently absent. This species bears a somewhat strong re- 

 semblance to D. Icericollis, but is at once recognized by the characters given 

 in the table. 



Tjipe. Male and females in coll. Godman and Salvin. 



Habitat. One male and three females collected by Mr. Champion at Cerro 

 Zunil, 4000-5000 feet ; and a single female, Teapa, Tabasco (March, //. H. 

 SmitJi). 



DiCAioTHRiPS Championi, sp. nov. (PL 51. fig. 3 ; PL 52. fig. 3.) 



D. foveicoUis in part. 



cJ . Length 105 mm., breadth of mesothorax 0*8 mm. 



Closely allied to D. foveicoUis, slightly larger, with the abdomen longer but 

 less slender, the prothorax less strongly foveolate, and the fore-legs slightly 

 stronger. Post-ocular bristles (absent in the male of fuveicoUis) present. 

 The seventh and eighth abdominal segments are considerably longer than in 

 foveicoUis and practically subequal, the eighth being but slightly shorter than 

 the seventh, whilst the tube is the same length as the seventh body-segment. 



T^pe. One male in coll. Grodman and Salvin. 



Habitat. Cerro Zunil^ 4000-5000 feet (^Cliampioi). 



DiCAIOTHRIPS L^VICOLLIS, sp. nov. (PL 51. figs. 5 & t) ; PL 52. figs. 

 5, a, h, & 6.) 



J . Length 7*5 mm., breadth of mesothorax 0'7 mm. 



Colour dark chestnut-brown ; fore-tibiae and all tarsi yellowish brown ; 

 third and fourth antennal segments yellow, tipped with brown, basal half of 

 fifth and base of sixth also yellow. 



Head cylindrical, almost three times as long as wide near base, narrowed 

 behind eyes and very slightly widened before constriction at base ; vertex 

 produced beyond eyes for about one-ninth the total length of head. Cheeks 

 set somewhat closely with short spines. Eyes bulging, moderately large and 

 finely facetted ; post-ocular spines absent ; ante-ocular spines (protecting 

 anterior ocellus) very long. Ocelli rather large, placed as in J) . foveicoUis 

 (Bagnall), but the space between the eyes, and consequently between the
