626 L. Bruner: 
Hedotettix burri Hancock. 
Seven specimens of the genus Hedotettix from varıous Madagascaren localities, Mauritius and 
Deutsch-Ostafrika are placed here. Part of them were preserved in spirits and make poor cabinet specimens. 
They were taken by Voeltzkow. 
Hedotettix pulchellus Bolivar. 
Six specimens of a second species of the genus Hedotettix are determined as Bolivars pulchellus. 
They are mostly from Madagascar and Pemba Isl. localities, and were taken by Dr. Voeltzkow. 
A single specimen is labeled Deutsch-Ostafrika. 
Family Eumastacidae. 
Penichrotes alatus n. sp. Fig. 4. 
Characterized by the presence of abbreviated tegmina and wings, the latter strongly infuscated. 
Antennae unicolorous, pallid, about equal to the anterior femora in length, the basal joint elongate, eylindrical, 
robust, the 2nd globular and of the same diameter as the 1st, remainder slenderer, the 5th to 9th gently 
flattened. Vertex as described for genus. Pronotum cylindrical, the median carina faint, anterior edge 
truncate, posterior edge excised at middle, paralleled by an elevated blunt ridge that follows across the 
disk and down the sides a short distance from the border, the intervening space finely and closely punctate. 
Hind femora moderately robust, the three upper carinae minutely toothed, the apex faintly infuscated; the 
hind tibiae 18-spined externally, 14-spined internally, the latter much the larger. Valves of ovipositor 
long and slender, infuscated below and internally; last ventral segment tricarinate, elongate cuneate. 
Color (alcoholie) uniformly pale testaceous with the exception of the eyes which are piceous, the 
spines and portions of ovipositor etc. as described above. 
Length of body, 9, 34 mm, of pronotum, 4,1 mm, of tegmina, 7 mm, of hind femora, 16,5 mm, of 
hind tibiae, 16 mm. 
Habitat: A single female taken at Sainte Marie (O. Madagaskar), during the month of August, 
1904, by Voeltzkow. 
Aside from the presence of tegmina and wings the present insect agrees exactly with the charac- 
terization of Penichrotes, hence it seems to be necessary to change the wording of the description of the 
genus so as to include winged as well as apterous forms. 
Penichrotes sp.? 
A single immature specimen of apparently a second species of Penichrotes comes from the same 
locality as the preceding. In this nymph there are traces of obscure markings on the hind femora, while 
in P. alatus the femora are uniformly pallid. 
Symbellia nigromaculata n. sp. Fig. 5. 
General color brunneous, the first abdominal segment testaceous marked basally with four 
conspicuous black spots on each side of the middle of the dorsum, second and third segments likewise 
maculate with several smaller and less conspicuous dusky blotches. Lower portion of front pallid, the 
antennae pale ferruginous; the valves of ovipositor long, slender, testaceo-ferruginous.
