volvuli (fpomaea crassipes} but not actually seen in the flowers. 

 Makes its nest in the ground. 



*i75. An. convolvuli Ckll. Chiyaka, Dec. 20, 1906. On 

 Convolvulus. 



*i77. Crocisa wcllmani Ckll. Chiyaka, Dec. 20. 1906. On 

 Aeolanthus and also on Orthosiphon sp. {? violaccus) . I think 

 this species is parasitic on Anthophora convolvuli (No. 175), 

 but I have not yet definitely proven it. 



178. Cr. meripcs Vach. Chiyaka, Dec. 20, 1906. On Aeo- 

 lanthus. At Professor Cockerell's suggestion I have followed 

 up the habits of this species and find that it is parasitic in the 

 nests of Anthophora qnadrifasciata (No. 171). 



90. Xylocopa tarsata Sm. var. wellmani Ckll. Bailundu, 

 Angola, February and March, 1906. Middle of rainy season. 

 At Long. E. 16, Lat. S. 12 13' 30". Altitude 4761 ft. 

 Taken at various Malvaceae, principally Gossypium spp. 



89. Mcsotrichia mixta Rad. Chiyaka, July, 1906. Seen at 

 several flowers. The specimens sent were taken at a species 

 of Millettia, of which they are very fond. 



1 80. Note on a Mite Found Infesting Mcsotrichia mixta. 

 After receiving Professor Cockerell's notes on Mcsotrichia, I 

 dissected several specimens of mi.\ta and in each case found 

 a peculiar pouch, opening on the basal surface of the first ab- 

 dominal segment, full of mites. I sent the contents of one of 

 these pouches (16 mites) with the specimens of bees, and they 

 have been identified as Paragrcenia. 



SUPPLEMENTARY NOTE. The new species have been described in 

 Annals and Magazine of Natural History, 1907. The Trigona I have 

 failed to identify, but hesitate to describe as new. It is nearly 6 nun. 

 long, black, with light ferruginous hair on thorax above ; clypeus shining, 

 with an orange mark at each side ; basal half of scape largely red ; a 

 yellow stripe along inner orbits ; a yellow line or band circling thorax, on 

 upper edge of prothorax, and margins of mesothorax and scutellum ; 

 first two additional segments with a large cream colored spot on each 

 extreme side ; second abdominal segment extremely shiny. There are 

 two entire submarginal cells. Paragreeuia Ckll. n.n., is (lreenia Oude- 

 mans, 1900 (not K\rby) = Greeme//a Banks, 1904 (not Ckll. ). The mites, 

 which probably represent a new species, were sent to Mr. Banks. T. D.
