194 THE ENTOMOLOGIST. 



Allied to T. canifrons, Sm., which is a larger species, and 

 has the oral region, mandibles, and tarsi black. 



Trigona fulvopilosella, sp. nov. 



Black ; the extreme base of antennal scape, the coxse, trochanters, 

 the greater part of the four anterior femora, the base of the posterior, 

 tegulaB, and the abdomen, brownish red ; the apical abdominal seg- 

 ments more or less black ; the thorax densely covered with fulvous 

 pubescence ; wings hyaline, distinctly tinged with fulvous, the ner- 

 vures and stigma pale fulvous, the posterior nervures paler than the 

 anterior. ? . Length, 7 mm. 



Kuching, May and October (John Hewitt). 



The centre of the mesonotum and metanotum are bare of pube- 

 scence, probably, however, through the hair having been rubbed off. 

 The hair on the legs is black and stiff. The head has a white sericeous 

 pile. The stump of the transverse cubital nervure is placed shortly 

 Ijelow the middle of the first abscissa of the culiitus ; the recurrent 

 nervure is reaping-hook-shaped, t. e. the anterior half is roundly 

 curved towards the apex of the wing, the posterior part being straight 

 and oblique. The base of the hind tibiae is distinctly narrowed, the 

 latter not becoming gradually widened from the base towards the 

 apex ; the apical joint of the tarsi and the claws are rufo-testaceous. 



This species comes nearest to T. erijthrog aster, Cam. ; the 

 latter may be known from it by the thorax not being covered 

 with fulvous pubescence, by the hind tibise becoming gradually 

 narrowed from the base to the apex, the base not being distinctly 

 narrowed, by the stump of the recurrent nervure being received 

 above the middle of the basal abscissa of the cubitus, and by 

 the recurrent nervure not being hook-shaped but straight. 



Trigona fusco-balteata, sp. nov. 



Black, smooth, shining ; the antennal scape, apex of clypeus, 

 labrum, mandibles, except at base, and more or less of the coxae and 

 trochanters, rufo-testaceous ; the under side of fiagellum of a darker 

 rufous colour ; abdomen pallid testaceous, the base of the segments 

 broadly banded with fuscous ; wings hyaline, the nervures and stigma 

 dark testaceous ; the basal abscissa of cubitus straight, oblique, un- 

 broken. The head anteriorly from the lower half of the front densely 

 covered with depressed white pubescence ; the thorax with longer 

 white pubescence, which is longer and denser on the pleurae and 

 sternum, especially on the latter ; the sides and apex of the scutellum 

 are fringed above with long pale hair. ^ . Length, 3 mm. 



Medang, Sarawak (Hewitt). 



The knees and apex of tibiae may be testaceous, as may be also 

 the base of the legs. The pubescence on the mesonotum is thicker 

 round the edges, and it may appear as longitudinal stripes down the 

 centre. The fuscous bands on the back of the abdomen are more dis- 

 tinct — darker — in some specimens than in others.
