644 L. Bruner: Acridoidea from Madagascar, Comoro Islands and Eastern Africa. 
of narrow alternately pallid and brown lines which cross the eyes parallel to their anterior border. Frontal 
costa prominent, broad, smooth and faintly punctate near the edges, not at all sulcate. Pronotum but 
gently expanding on the hind lobe which is nearly as long as the anterior one, the transverse sulei faint, 
the hind one alone severing the median carina; the hind margin subangulate. Tegmina in the male some- 
what surpassing, in the female just about reaching the tip of the abdomen. Hind femora moderately robust 
on basal half, the apical half slender; hind tibiae with ten pale, black-tipped spines in both outer and 
inner rows. Prosternal spine somewhat robust, gently retrorse, the sides parallel and the apex bluntly rounded. 
Length of body, d, 22,5 mm, 9, 37 mm; of pronotum, d, 4,85 mm, 9, 6,1 mm; of tegmina, d, 19 mm, 
9, 25 mm; of hind femora, d, 14,5 mm, 9, 20 mm. 
Habitat: Sainte Marie (OÖ. Madagaskar) and the Comoren Archipelago. 
This species is readily recognized by the small number (10) of tibial spines and by the unicolorous 
hind tibiae. It is one of the species that evidently enjoys a rather wide distribution in East Africa and 
the adjoining islands. 
Euprepocnemis antennata Brunner. 
The collection contains several specimens of a beautiful large species of this genus that agree 
with two specimens in the present writer’s collection that bear the label EP. antennata. These latter were. 
received direct from Brunner von Wattenwyl, and were also taken in Madagascar. Henry de Saussure 
describes an insect under the name Horaeocerus nigricornis (Abhandl. d. Senckenb. naturf. Ges. Bd. XXI, 
1899, p. 6355—636, figs. 33—35) which is very similar to if not identical-with, Brunner’s specimens. 
The material at hand in the collection now being studied comes from central and southwestern 
Madagascaren localities and contains specimens with pellucid as well as others with strongly maculate 
tegmina. Those with the plain tegmina appear to have the enlarged antennae, while those with the macu- 
late tegmina have them rather slender, even in the males. There are no males at hand with the pellucid 
elytra. Otherwise the two insects are very similar in size and color, and seem to possess no other distingui- 
shing characters. Even the antennae vary as to their robustness in the pellucid tegmina form. If 
Brunner’s species was described his name may have priority, if not, Saussure’s should be given to 
these insects. 
Tylotropidius sp.? 
A single female specimen of this genus is represented among some material coming from Mombasa, 
East Africa, where it was taken on the 10th of February, 1903. Long preservation in alcohol has obliterated 
many of the determining characters. It evidently comes close to the 7. pendulus (Karsch) if it is not 
that insect. 
Cataloipus oberthuri Bolivar. 
Specimens of a Cataloipus coming from the Island of Pemba are determined as Bolivar’s ober- 
thuri. Both sexes are at hand, some of them dried and others preserved in spirits.
