824 REPORT OF THE HARVARD AFRICAN EXPEDITION 
The penis of this male agrees perfectly with Rothschild’s drawing of this 
organ in C. villosus, a species known thus far from Transvaal and Nyasaland. 
In the Transvaal Dr. H. Brauns found it on Eptesicus capensis (A. Smith). 
DERMAPTERA 
HEMIMERIDAE 
Hemimerus hanseni D. Sharp 
Hemimerus hanseni D. Sharp, 1895, ‘Cambridge Natural History,’ V, p. 217, figs. 114-116. Rehn, 
1924, Bull. Amer. Mus. Nat. Hist., XLIX, p. 352 (# 9). 
Breuc1an Conco. — Burunga, off Cricetomys gambianus Waterhouse, March 
23, 1927. 
This peculiar parasite is known from the Gold Coast, Cameroon, the Belgian 
Congo, Uganda, Kenya Colony, and Tanganyika Territory. A species of 
Hemimerus, taken in Liberia by O. F. Cook, has been referred to H. talpoides 
Walker (originally described from Sierra Leone) and this identification was 
possibly correct. 
ORTHOPTERA 
The following notes on an interesting wingless grasshopper of the Kivu 
voleanoes, have been contributed by Mr. J. A. G. Rehn, of the Academy of 
Natural Sciences, Philadelphia, who has kindly named the specimens obtained 
by the Harvard Expedition. 
ACRIDIIDAE 
SUBFAMILY PyROMORPHINAE 
Parasphena ruandensis Rehn 
Parasphena ruandensis Rehn, 1914, Wissensch. Ergebn. Deutschen Zent.-Afr.-Exped. 1907-1908, 
V, Zool., II, Lief. 1, p. 99 (# 9; Ninagongo, Virunga Volcanoes, north of Lake Kivu, 3,000 
meters elevation, type locality; JKarissimbi, Virunga Volcanoes, 2,900 meters elevation; 
southeast shore of Lake Kivu; Rugege Forest, southwest Ruanda, 1,800 meters elevation; 
Bugoie Forest, northwest Ruanda, 2,500 meters elevation. ) 
BELGIAN Congo. — Kabara in the saddle between Mt. Mikeno and Mt. 
Karissimbi, at an elevation of 10,500 feet, Virunga Volcanoes, March 16, 1927. 
Male and female, taken in copula. 
The Kabara specimens have been compared with a series of the original 
material of the species, including four male paratypes from Ninagongo, and no 
important or noteworthy differences are apparent. The species exhibits a dis- 
tinct amount of individual variation in the length and robustness of the antennae, 
regardless of sex or locality. However, this variation is in the thickness and 
length of the segments, the number of which is not increased or diminished. 
There is also some variation in the exact curvature of the lateral margins of the 
fastigium, which is equally individual in character. 
The genus Parasphena is restricted to Ethiopian Africa, ranging from Eritrea
