swelling of the notum concave in the middle and expanded laterally 
into strong spines. Mesosternum granulose and laterally spinose. 
Metathorax transverse, rectangular. Median segment about 0.8 
times the length of metanotum. 
Abdominal segments transverse, segments II-VII laterally expanded 
into spinose lobes, VIII-X narrower than the preceding. Supraanal 
plate small, triangular. Cerci short, slightly curved. Sternite VII 
with a postero-median praeopercular organ ; subgenital plate elongate, 
extending beyond the apex of the abdomen, acuminate apically. 
Legs elongate and slender. Anterior femora straight basally. Four 
posterior tibiae anareolate. First tarsomere slightly longer than the 
next two together. Tegmina and wings absent. 
Male: Unknown. 
Type species: Taraxippus pciliurus Moxey, new species. 
Distribution : This genus is known only from the type locality 
in the northwestern part of Haiti. 
Derivation of name: Taraxippus, the horse-scarer, was the name 
given to the ghost of Glaucus. 
The state of the suprageneric classification of the phasmatids is 
in such chaos that it is extremely difficult to place this remarkable 
genus in the present scheme. At first glance, it would appear to 
belong to the pygirhynchine genus Mirophasma Redtenbacher 
(1906), but it can readily be excluded from this group on the basis 
of its anareolate tibiae and the relatively large median segment. It 
would thus seem to belong to the Phibalosomatinae, being somewhat 
related to Lamponius Stal (1875), from which it may be distin- 
guished by its basally straight anterior femora and the elongate first 
tarsomere. It is unfortunate that the male of Taraxippus is not 
known, for it would help to resolve its relationships; I have some 
reservations about describing it at all from a single specimen, but 
it is so interesting, that I feel more is to be gained by placing a 
name in print than bv not. 
Tbe females of Taraxippus f>aliurus n.sp. (Figures 2 and 5), 
Tamponius restrictus (Redtenbacher, 1908) 1 (Figures 3 and 6), and 
1 Originally described in the genus Pericentrus Redtenbacher (1908), this 
species was placed in Antillophilus Carl (1913) by Rehn & Hebard (1938). 
My recent collecting in Puerto Rico convinces me that Antillophilus (type 
species: A. brevitarsus Carl), is a junior synonym of Lamponius Stal (type 
species: P\girhynchus guerini Saussure, 1868). Thus, the species of 
Lamponius are: L. guerini (Saussure), L. portoricensis Rehn (1903), L. 
kfugi Redtenbacher (1908), L. bocki Redtenbacher (1908), L. restrictus 
(Redtenbacher, 1908), new combination, L. brevitarsus (Carl), n. comb., 
and L. dominicae Rehn & Hebard (1938).
