34 ME. V. CAMERON ON ttte [May 7, 



the 1st recurrent nervure is not interstitial, but is received shortly 

 beyond the 2nd transverse cubital. Tegulffi rufous, black round 

 the inner edges. The hair on the legs is dense, long and bright 

 rufous : the tooth on the apex of the fore tibia? is short, blunt, and 

 hollowed on the outer side. The hair on the abdomen is similarly 

 coloured to that on the thorax : it is sparse on the back ; the ven- 

 tral segments are fringed with long hair; unless the segments are 

 distorted, the 4th is distinctly longer than the 3rd. 



A distinct species ; the rufous colour of the pubescence makes it 

 resemble rufegcens Smith ; but, apart from other differences, that 

 species is a Koptorthosoma, whereas the present species is a Xylocopa 

 s. str. It is a well-marked species, through its head being larger 

 and more particularly wider, compared with the thorax, than usual, 

 most of the species having the head very perceptibly narrower than 

 the mesothorax ; the ocelli too are larger and are placed in a 

 triangle, while with most of the species, e. g. rufescens, they are 

 placed in a curve ; they are also placed nearer to the eyes than in 

 the typical species of Xylocopa.']

The scape of the antennae rufous ; the flagellum black, brownish 

 beneath. Except on the clypeus the head is thickly covered with 

 bright fulvo-rufous hair ; the face is strongly punctured : the 

 clypeus is more closely rngosely punctured and is strongly keeled 

 on the upper two-thirds ; it is covered (but not so thickly as the 

 front) with longish dark rufous hair ; on its sides there is a patch 

 of thick fulvous hair, which is obliquely narrowed towards the 

 apex. The apical tooth of the mandibles is bluntly rounded ; the 

 subapical tooth is short, broad, bluntly rounded, and is furrowed 

 broadly, but not deeply, in the middle. The entire upper part of 

 the thorax is thickly covered with bright rufous hair, except in the 

 centre of the median segment. The pleura? are also thickly covered 

 with similar pubescence. Mesosternum closely rugosely punc- 

 tured aud covered with pale fulvous hair. Legs rufous ; the coxae 

 and the four anterior trochanters black ; the hair is thick, stiff, and 

 dark rufous; the tarsi are darker in colour, especially towards the 

 apex. Wings fulvo-hyaline, the apex slightly smoky ; the stigma
