Length of body, d, 13 mm, 9, 17,5 mm; of pronotum, d, 3 mm, 9, 4 mm, of tegmina, d, 2 mm, 
9, 2,5 mm; of hind femora, d, 7,5 mm, 9, 11,5 mm. 
Habitat: Three males and two females collected by Dr. Voeltzkow during May, 1904 at 
Fianarantsoa (SE. Madagascar). 
While Catantops is the most important African genus of the family in point of the number of 
species belonging to it, only five of them are contained in Voeltzkow’s collection. Two of these have 
recently been described by H. Karny in his revision of the genus (Sitz. k. k. Akad. Wiss. Wien, math.- 
nat. Klasse, CXVI, Abt. 1, February, 1907, p. 309—352). 
Catantops decoratus Gerstäcker. 
A pair of this species are at hand. They were collected at Chake-Chake on the Isl. of Pemba 
(British East Africa), April 14, 1903. 
Catantops melanostictus Schaum. 
This species is represented by three males and two females. They were taken, according to the 
labels they bear, in the Mafia Archipelago (German East Africa) and Lamu (British East Africa). 
Catantops sacalava Brancsik. 
Catantops sacalava Brancs., is represented by several specimens of both sexes which come from 
Madagascaren localities and the Comoro Islands. 
Catantops malagassus Karny? 
Three specimens of a medium sized Catantops from central and East Madagascar are referred 
doubtfully to Karnys malagassıs. Two of them were collected during September, 1904. The third does 
not bear a date record. 
Catantops brunneri Karny. 
By far the largest series of a species of this genus belong to the €. brunneri Karny. There are 
more than 100 specimens coming from different islands in the Comoro Archipelago, Mombassa and 
adjoining regions. This is a very striking insect in appearance, and undoubtedly is sufficiently numerous 
to be destructive if it is a general feeder. 
Caloptenus mossambicus Brancsik. 
The collection contains three specimens, two males and one female, of ©. mossambicus Brancs. 
They were collected at Chake-Chake on the Island of Pemba (British East Africa), April 14, 1903. It 
is readily recognized by having the longer inner spur of the hind tibiae provided with a hairy prolongation 
at the base of the strongly carved claw.
