638 L. Bruner: 
Lentula minor n. sp. Fig. 14. 
Entirely apterous, dull brunneo-testaceous, possibly olivaceous in life, with the meso- and metasternum, 
the apex of hind femora internally, the lunules externally, the base of hind tibiae internally, and beneath 
black, the latter, together with the first tarsal joint, also infuscated apically internally. Size much smaller 
than L. obtusifrons Stäl, of which it is a diminutive. 
Body somewhat compressed, viewed laterally evenly arcuate, the altitude greatest at hind margin 
of the insertion of the middle pair of legs. Head large, a little wider than high, and with rounded heavy 
cheeks and short stout anteriorly projecting mouth-parts giving the insect a bulldog appearance; eyes large, 
prominent, elongate elliptical, more than twice the length of the cheeks below them, separated above by a 
space little more than one-half the distance between the bases of antennae, deeply sulecate, the fastigium 
very short, wide and greatly depressed, separated from the frontal costa by a faint transverse carina; the 
frontal costa very indefinite in outline, much widest above the ocellus, continued to the clypeus. Antennae 
filiform (incomplete), in the specimen being described. Pronotum short, its height two and one-half times 
the length, the median carina inconspicuous as are also the transverse sulci; anterior and posterior edges 
truncate. Abdomen and meso- and metanotum carinate with a very fine suleus extending along its middle 
throughout. Hind femora of moderate length, fusiform, compressed, the pennae of outer face arcuate and 
continuous across the disk; hind tibiae moderately robust, lengthly and profusely hirsute, five-spined 
externally and eight-spined internally. Hind tarsi quite long, hirsute, the three joints about equal in length. 
Apex of abdomen acuminate, the valves of the ovipositor small and quite strongly curved at the tips, the 
supra-anal plate moderately large and plainly divided into two nearly equal parts by a profound transverse 
sulcus, the basal half broadly sulcate at middle. Prosternal spine short, heavy, obtuse. Anterior and 
middle legs short, the femora robust and gently arcuate. 
Length of body, 9, 18 mm, of pronotum, 2,85 mm, of hind femora, 10 mm, of hind tibiae, 9 mm. 
Habitat: The only specimen at hand, a female, was collected on Patta Island (British East Africa), 
November, 16, 1903, by Professor Voeltzkow. 
This insect is very similar to the various representatives of the American genus Bhicnoderma, 
but is generically distinet on account of the much narrower vertex, the rougher or more strongly punctate 
head and thorax, ete. Still the two genera seem to have had a common ancestry. It no doubt is arboreal 
in habits and should be searched for among the undergrowth near the edges of forests. 
Oxyrrhepes procerus Burmeister. 
There are a number of both sexes of this locust in the collection coming from the Comoro Archi- 
pelago where they were taken during July, 1903. Some of the specimens were preserved dry, while 
others were placed in spirits and formalin. 
Oraistes luridus Karsch. 
A single pair of this species was taken at Chake-Chake on the Island of Pemba. They were 
collected in April and May, 1903. 
Ischnacrida hova Karsch. 
The only representative of the genus Ischnacrida at hand is I. hova, a female specimen of which 
was taken during February, 1904. It bears the label Andranohinaly (SW. Madagascar), Waldgebiet.
