Pycnodyctia galinieri Reich et Fairm.? 
A single male specimen of a locust coming from Andranohinaly (SW. Madagascar) where it 
was collected during February, 1904, and preserved in alcohol, is referred with some doubt to this species. 
This specimen under consideration is somewhat smaller than the measurements given by Saussure 
in his Prodromus Oedipodiorum, while the pronotum has the median carina of the anterior lobe decidedly 
more elevated than that portion on the hind lobe from which it is separated by a profound sulcus. The 
superior and inferior carinae of the hind femora are quite strongly serrated, while the tegmina are rather 
evenly conspersed with fuscous markings that do not form definite transverse bands. The measurements 
of the present specimen are as follows. 
Length of body, 24 mm, of pronotum, 6,85 mm, of tegmina, 24 mm, of hind femora, 16 mm. 
Trilophidia cinnabarina Brancsik. 
The collection contains several specimens of Brancsik’s T. cinnabarina. They come from Tulear 
(SW. Madagascar) and from the Ile aux Prunes (E. Madagascar). Those from the latter locality are 
noticeably smaller than the others, but I do not consider them to be sufficiently distinet to be given even 
a varietal name. 
Trilophidia minor n. sp. 
Similar te T. anmulata (Thunb.) in general structure and color but decidedly smaller and with 
somewhat shorter tegmina and wings. 
General color fulvous varied with dark brown and black. Antennae faintly annulate with fuscous. 
Face, sides of pronotum, plura, abdomen above and femora irregularly conspersed with black or dark 
brown; the tegmina widely bifasciate with fuscous, the apical two-fifths evenly conspersed with dark brown. 
Disk and base of wings flavous. Hind tibiae widely fasciate with flavous and black, the spines large, 
robust, pallid with black tips. 
Length of body, 9, 17—18 mm, of pronotum, 3,6 mm, of tegmina, 17,5 mm, of hind femora, 
8,25 mm. 
Habitat: Chake-Chake, Isl. of Pemba, 1 ©, April 20, May. 1, 2 29, 1903, Prof. Voeltzkow 
collector. 
Possibly the difference in structure between this insect and typical 7. annulata (Thunb.) is not 
sufficient to form a distinct species. It will certainly be a well-marked variety. 
Acrotylus patruelis Sturm. 
Specimens of this widely disseminated species are present from a number of localities both in 
Madagascar and the adjoining islands. It varies but little either in size or color. 
Acrotylus sp. 
A single alcoholic specimen from the island of Manda (British East Africa) seems to differ from 
patruelis but cannot be determined.
