Physothrips brunneicorm's, sp. n. 



? . — Length 1'4 to 1*5 mm. 



Colour brown, the antenna?, head, prothorax, intermediate 

 and hind femora and tibia?, and apical abdominal segments 

 inclined to be darker. Antennae unicolorous, fore-tibijB 

 yellow, shaded with greyish brown along margins ; all tarsi 

 yellow. Fore-wings faintly clouded with light grey-brown 

 near base ; basal third or thereabouts clear, thence smoky- 

 brown to tip excepting for an ill-defined clear patch at about 

 the commencement of the distal fifth ; setee and cilia dark. 



Head about 0*7 as long as broad and not quite as long as 

 the prothorax ; a defined area of the dorsal surface behind 

 transversely striated. Eyes coarsely facetted, minutely 

 pilose ; cheeks not arched, tending to widen posteriorly ; 

 ocelli large, posterior pair above a line drawn across hind 

 margins of eyes ; interocellar bristles long and strong, placed 

 between the anterior ocellus and the posterior pair. Antennae 

 seated below vertex, about 2'5 times as long as the head ; 

 relative lengths of joints 3 to 8 as follows : — 22 : 22 : 14 : 

 20 : 5 : 6. Joints 5 and 6 somewhat broadly united and 

 distinctly more slender than the preceding ; forked trichomes 

 on 3 and 4 long and stout. 



Prothorax much as in P. usitatus. 



Fore-wing and arrangement of setse as in P. usitatu<i. 



Abdomen about 1*15 times as broad as the pterothorax, 

 segments 9 and 10 obconical ; apical bristles long and stout ; 

 9 with a rather short dorsal pair widely separated. 



This species very closely approaches P. usitatus, Bagn., 

 but is at once separated from it (as well as from sjostedti, 

 Trybom, and variabilis, Bagn.) by the unicolorous antenna. 

 The antennal joints 3 and 4 would appear to be stouter and 6 

 shorter than in usitatus, whilst the fore-femora are concolorous 

 with the prothorax.
