HEMIPTERA-HETEROPTERA, 391 
ISCHNODEMUS (p. 195). 
Ischnodemus precultus (p. 196). 
To the locality given, add :—Panama, Caldera (Champion). 
In the specimens from the State of Panama the corium and membrane are more or 
less shaded with dark fuscous. The length of the third joint of the antenne is variable 
in specimens now before me. 
8. Ischnodemus cahabonensis, n. sp. (Tab. XXXIV. fig. 20.) 
Head, pronotum, and scutellum black; posterior margin of the pronotum, the corium, and membrane 
ochraceous ; abdomen above castaneous, greyishly pilose, its lateral margins ochraceous. Femora black ; 
their apices, the tibie, and the tarsi ochraceous, the apical joint of the tarsi black. Antennz black, the 
basal joint and the eyes castaneous. Pronotum constricted behind middle, the anterior lobe wide, sub- 
globose, and pilose, the constriction being broad and transversely striated. (In the specimen described the 
corium and membrane are in a rudimentary condition.) 
Long. 7 millim. 
Hab. GuatTEeMALA, Cahabon in Vera Paz (Champion). 
By the colour of the legs this species is allied to J. tibialis and I. nigro-stillatus, 
Stal, described from Rio Janeiro, but it differs from both by the bi-coloured pronotum. 
A single example is all we have received. 
4. Ischnodemus umbratus, n. sp. (Tab. XXXIV. fig. 21.) 
Head, pronotum, scutellum, clavus, legs, and antenne black; apices of the femora and tibie, and the tarsi, 
ochraceous. Corium ochraceous, with its inner area blackish; membrane fuscous, with the margins 
greyish. Abdomen above dark castaneous and greyishly pilose, its lateral margins obscure ochraceous. 
Long. 6 millim. 
Hab. GuateMata, San Gerénimo (Champion). 
Allied to the preceding species, L. cahabonensis, but with the pronotum concolorous 
and its anterior lobe shorter; it also differs by the colour of the legs, corium, membrane, 
&c. As in our solitary example of the preceding species, the corium and membrane 
are in a rudimentary condition. Mr. Champion sent us a single (carded) specimen. 
' TOONGLASA, gen. nov. (To follow the genus Jschnodemus, p. 196.) 
Lateral margins of the apical segment of the abdomen produced into a long curved spine on each side; legs 
short, the femora strongly incrassated ; anterior femora with a very strong spine near apex. Head about 
as broad as long, triangularly produced in front of the eyes, and strongly constricted and moderately 
-exserted behind them ; narrower than the anterior margin of the pronotum ; prominently spinous near the 
base of the antenne. Antenne with the basal joint short, globose, and about reaching the apex of the 
head, second joint a little longer than the third (remainder mutilated). Pronotum broad, with its lateral 
margins rounded anteriorly, the anterior margin concavely sinuate, and little more than half the breadth
