GEOGRAPHICAL DISTRIBUTION OF THE SPECIES AND SUBSPECIES. 



Lasiopyga is strictly an African genus and its members are dis- 

 persed over the entire continent, save the extreme northern part lying 

 along the Mediterranean Sea. They are also found on the large island 

 of Fernando Po, but not on Madagascar. Of the known species about 

 thirty-nine are East African, thirty-four West African, two South 

 African, both ranging northward on the east and west coasts, and the 

 dispersion of six remaining species is quite unknown. It will thus be 

 perceived that there are something like eighty species and races at 

 present recognized and doubtless many more are yet to be discovered, 

 as the interior of Africa is better known. Beginning in the north- 

 eastern portion of the continent, we have in the region of the White 

 Nile, L. NEGLECTUS Schlegel, its range unknown, probably somewhat 

 restricted as the type is still unique although the species was described 

 over thirty years ago. On the Upper Nile in Sennaar, Kordofan and 

 Abyssinia, L. griseoviridis ranges ; while from Southern Abyssinia to 

 Lake Rudolph. L. boutourlini has its home. In the same kingdom 

 in the dark forests through which the Omo and Sobat rivers flow, L. 

 MATSCHiE was discovcrcd, and in the forest of Djamdjam east of 

 Lake Abaya, L. djamdjamensis was procured. In the Galla country 

 west of Somaliland at the head waters of the Webbi Schebeli, L. hil- 

 gerti was met with. On the Juba River, along the boundary of British 

 East Africa, and extending southward to the west shore of Victoria 

 Nyanza, and thence into Ankole at 5,000 feet elevation, also on the 

 islands of Dakota and Sesse, L. centralis is found ; and in the Great 

 Rift Valley on the south side of Lake Naivasha, L. callida was taken. 

 North and west of Lake Albert, and also southward to Lake Kivu, on 

 Kividjvi Island in the lake, L. stuhlmanni is found, and at the 

 south end, L. aurora was discovered : while west and south of Lake 

 Albert L. princeps was procured ; and between the lakes Albert 

 Edward and Victoria Nyanza, L. budgetti was met with, and L. 

 Doggetti in Southwest Ankole, and to the west of the same lake, 

 at Bembara, L. griseisticta was taken. On Mt. Ruwenzori, at 

 an elevation of 10,000 feet, on the eastern side, L. carruthersi was
