Type. — At least a part of Sichel's type specimens are in 

 the collection of the k. k. Hofmuseum at Vienna, as is also 

 Dalla Torre's type of corsiais. Smith's bellicosus is, in all 

 probability, thoracicus. The type of bellicosus is in the collec- 

 tion of the British Museum. 



Malar space rather short. Females with dorsum of thorax varying 

 from light yelloiv to ferruginous, ivith no black interalar band ; pleura 

 dark ; dorsum of abdomen black, zvith the three apical segments ferru- 

 ginous ; legs black. Males with short malar space ; third and fourth 

 antennal segments subequal ; coloration as in females, but with more 

 or less yellow on pleura, abdomen variable atid legs with considerable 

 yellow pile. 



Queen. Head. — Mostly black, sometimes with a slight sprinkling of 

 yellow hairs among the black on the occiput or about the bases of the 

 antennae. Malar space a trifle shorter than its width at apex, not over 

 one-fifth as long as eye. Clypeus coarsely punctate, but rather sparsely 

 so on the front portion of its disc. Third antennal segment longer than 

 fifth and fifth longer than fourth. 



Thorax. — Dorsum clothed entirely with pile of a color var>'ing from 

 pale yellow to deep yellow and even to ferruginous-red, with no black 

 interalar band. Pleura black from level of bases of wings to bases of 

 legs. 



Abdomen. — Dorsum : three basal segments entirely black (some 

 specimens, however, with a considerable sprinkling of yellow pile on 

 the basal middle of the second segment); three apical segments en- 

 tirely covered with ferruginous-red pile. Venter for most part black, 

 but with apical margins of apical segments fringed with yellowish fer- 

 ruginous hairs. Hypopygium without median carina. 



Wings. — Very dark, with slight violaceous reflections. 



Legs. — Coxae, trochanters, femora and tibiae, including corbicular 

 fringes, all black. 



Worker. — Much like queen ; but pile on dorsum of thorax tending to 

 be paler and the ferruginous pile on the apical abdominal segments 

 somewhat lighter, as a rule, than in that caste ; wings somewhat 

 lighter. 



Male. Head. — Malar space considerably shorter than its width at
