A NEW GALL-MAKING THRIPS. 

 By G. II. Hardy. 



(Received 4th October, 1915. Read loth November. 

 Issued separately 31st December, 1915.) 



Kladothrips Rodwagi, Sp.n. 



Imago. Winged ; body shining black ; antennae gener- 

 ally very pale yellow, sometimes black ; anterior tibiae 

 yellow or reddish yellow ; anterior femora suffused with 

 reddish, or entirely black ; the two small apical joints of 

 the intermediate and posterior legs whitish. Length 3 

 mm. 



Larva. Although I searched numerous galls, I failed to 

 find anything I could consider a nymphal or pronymphal 

 condition. The larvae are variable in colour and mark- 

 ings, starting from very pale yellow or white when young, 

 reaching a condition that is well marked with black. An 

 advanced form of larva has all extremities (namely the legs, 

 antennae and eyes, and the last segment of the abdomen) 

 shiny black, and also two large black spots on the pro- 

 thorax. Down the abdomen there is sometimes a pair of 

 dark thin stripes, increasing in intensity and converging 

 towards a point, often ending in a ring near the ar>ex, but 

 not reaching the apical segment. 



Galls. Similar to those made by Kladothrips rugonu 

 (Frog.), as illustrated by fig. 5b. in Mr. Froggatt's article 

 in the "Agricultural Gazette" of N.S.W., 1906. Larvae 

 and imagos inhabit the same gall, and generally the smaller 

 the gall and the more shrivelled the leaf, the bigger the 

 percentage of imagos to be found in them. 



Habitat. Ilobart, May, 1915; in galls on Acacia melon- 

 oxylon (Blackwood). 



Mr. Froggatt in his above-mentioned article, pg. 1,011, 

 gives a description of his Kladothrips rugonu; a technical 

 description has not yet boon published for the genus. A 

 rodwayi is very near A', rugonis, and differs from the de- 

 scription chiefly in having the thorax and the first segment 

 of tho abdomen black.
