NEW GENEEA .IKD species OF AUSTRALIAN XaTSANOPTEMA—HOOD. 147 



Genotype : Phaulolhrips vuillcti sp. iiov. 



Suggestive in many ways of Dice.ralolhrips, from which it may be known by the 

 •Jonger head and the broad, deeply emarginate prothorax. The thickening of the 

 anterior margin of the pronotum is an interesting character which occurs also in the 

 Neotropical genus DichceloUiri ns. 



PHAULOTHRIPS VOTLLETI si), nov. 



3Iule. {tmKropteroiis). — Length about 3-3 mm. Colour dark blackish brown or 

 black, with third antcnnal segment, fore tarsi, and apex of fore tiljise, j'ellowish. 



Head slightly more than twice as long as wide, sides perfectly straight and 

 parallel ; dorsal and lateral surfaces faintl_y reticulate with anastomosing lines, especially 

 at base ; vertex not produced, front broadly emarginate, overhanging insertion 

 of antenna; and with a pair of long, strong, forwardly directed bristles each side of 

 emargination and a pair of minute bristles between and below these ; postociilar 

 bristles much longer than eyes, pointed ; cheeks with a pair of lateral bristles (half 

 the length of postoculars) behind eyes. Eyes about one-fifth as long as head and 

 above about as wide as their interval ; beneath, half as wide as their interval and with 

 the inner posterior angle acute. Ocelli nearly equidi.stant, the anterior ocellus directed 

 forward and upward. Antenna? slender, 1-72 times as long as head, intermediate 

 segments elongate, sense-cones verj^ short, stout ; formula : 3, 1-1 ; 4, 1-1 ; 5, 1-1 + ^ ; 

 6, 1-0 + 1 ; 7 with one on dorsum near ajiex ; segments 1, 2, and 4-8 dark blackish 

 brown, the apex of 2 yellowish ; 3 yellow, infuscate at apex. Mouth-cone not as 

 long as width at base, semicircular at apex, about attaining middle of presternum. 



Prothorax along median dorsal line about 0-43 as long as head and (inclusive of 

 coxa;) about 2-7 times as wide as long ; pronotum smooth, with heavy median thicken- 

 ing, and with the deeply emarginate anterior margin somewhat thickened ; the two 

 pairs of bristles at posterior angles long, iJointed, equal in length to postoculars, 

 other bristles minute. Pterothorax rectangular about equal in width to prothorax. 

 Wings long, broad, not narrowed at middle, hghtly washed with brownish. Fore 

 femora enlarged, about as long as head and 0-7 as broad ; fore tarsi with a long, 

 stout tooth. 



Abdomen broad and heavy. Tube 0-68 as long as head and 2-5 times as long as 

 width at base, which is about 2-4 times the apical. Sides sinuate, the apex constricted. 

 All bristles long and pointed, yellow, those at apex of segment 9 longer than tube ; 

 terminal bristles half as long as tube. 



Measurements of holotype : — Length 3-29 mm. ; head, length 0-588 mm., width 

 0-284 mm. ; prothorax, length along median dorsal line 0-252 mm., width (inclusive 

 of coxiB) 0-678 mm. ; pterothorax, width 0-672 mm. ; abdomen, width 0-732 mm. ; 

 tube, length 0-400 mm., width at base 0-160 mm., at apex 0-068 mm.
