Or 
SCHUMANNTA. 1&: 
SCHU MANNIA, n. gen. 
Head subcylindrical, produced anteriorly beneath the points of insertion of the antenna, the gene each armed. 
with a short porrect spine; the upper ante-ocular portion of about the same length as the post-ocular 
portion, the sides of the latter a little rounded and armed with a row of four laterally projecting stout 
setiferous spines ; frontal spines (jug) moderately long, porrect, divergent ; antenniferous tubercles each 
armed externally with a short spine; eyes rounded, very prominent; ocelli moderately prominent ; 
antennee very short, with joint 1 about as long as the entire anterior portion of the head ; rostrum short, 
joint 1 slightly longer than 2 and 3 united, the latter equal inlength. Prothorax elongate ; the propleura 
dilated anteriorly and extending forwards to beyond the base of the head; the prosternal spines very 
short and scarcely distinguishable from the setiferous spines on the anterior portion of the pleura; the 
anterior angles of the pronotum unarmed. Scutellum with a prominent erect tubercle at the apex, the 
post-scutellum also with a tubercle in front. Elytra ample, nearly reaching the apex of the abdomen, 
with the inner margin strongly sinuate before the apex, the latter pointed. Abdomen (<¢) elongate, 
widening to the middle, with narrow connexivum, the outer apical angles of the terminal segments more 
» or less angularly dilated. Anterior coxe inserted very far forwards. Anterior trochanters spinose and 
with one longer spine at the apex beneath. Anterior femora strongly incrassate, armed beneath. with 
rows of very short spines and with two or three longer spines at the base. Anterior tibim as long as 
the femora, and with a short spongy fossa at the apex beneath. Anterior tarsi with joints 2 and 3 fused 
into one, the other tarsi distinctly 3-jointed. Posterior femora not reaching the apex of the abdomen. 
Mesosternum greatly produced anteriorly, rounded in front. Body very elongate, narrow. 
A single species from Mexico is referred to this genus. It cannot be included in 
Ctenotrachelus, Stal, which has a short head and a very narrow, parallel body,.or in 
Sastrapada *, Amyot et Serv. (=Harpagoehares, Stal, and Ctenocnemis, Fieb.), the 
latter not having a spongy fossa at the apex of the anterior tibie beneath, &. 
1. Schumannia mexicana, n. sp. (Tab. XI. figg. 18, 184, 3.) 
&. Greyish-ochreous, mottled with fuscous; the head with a broad blackish: median vitta, separating into two 
narrow lines in front: the pronotum with a blackish median line, the anterior lobe in great part fuscous ; 
the scutellum black; the elytra with a pale greyish streak extending along the outer cell of the membrane 
to the apex, an interrupted, oblique fuscous streak, commencing along the inner margin and extending to 
near the apex, and a row of very small fuscous spots on the outer cell of the membrane ; the connexivum 
spotted with black; the legs and antenne ochraceous, the femora slightly speckled with fuscous, the 
anterior and intermediate tibize with the apex and some spots near the middle nigro-fuscous, the longer 
spines on the anterior trochanters and femora black, the tarsi fuscous; beneath ochraceous, mottled with 
fuscous ; the body sparsely pubescent, the pronotal margins, the propleura in front, and the ante-ocular 
pertion of the head. beneath, armed with short setiferous spines; the antenne and rostrum clothed 
throughout with long projecting hairs; the legs hairy, the anterior femora with two rows of short 
setiferous spines behind, as well as two rows of short spines beneath. Antenne with joint 1 much 
stouter than 2, 2 slender, nearly twice as long as 1, 3 very slender, short (4 broken off). Prothorax at 
the sides nearly twice as long as broad, narrowing from the base to the middle, and then becoming 
subcylindrical ; the pronotum with the posterior lobe much shorter than the anterior lobe, the latter 
canaliculate down the middle, and with a deep fovea in the centre and a sinuous groove on each side 
behind, the anterior margin thickened, and the hind angles obtuse and a little swollen. Abdomen 
gradually widening to. about the middle, with the outer apical angles of the segments becoming more 
and more dilated, that of the fifth segment strongly so; the fifth segment parallel; the sixth segment 
* §. longicollis, Walk., from the Amazons, is a C'tenotrachelus, allied to C. macilentus, Stal; S. filiformis, 
Walk., from the Amazons, is a Pnirontis.
