margins of furrow sometimes elevated into laminae. Sp. Physomertis dilati- 
cornis (Sign.), P. terminalis (Burm.), and Lygceus spinipes (Pal. B.). 
Homoiocerides, 
Plapigus (StSl). PenduUnus spinosus (Thunb.) is referred to this genus, 
and described from the type by StSl, Berl. ent. Zeits. 18GG, p. 169. 
Chondrocera foliaccata (Blanch.) is described as a species of Plapigus by 
Stal, Berl. ent. Zeits. 1866, p. 381. 
PenduUnus ater (Thunb.) = larva of Galcesus Jiasticomisy according to Stal, 
Hem. Afr. iv. p. 255. 
Diodes, g. n., StSl, Hem. Afr. ii. p. 68. Allied to Homceocerus ; joints 3 
& 4 of rostrum equal ; head immersed up to eyes in the thorax ; apical angle 
of coriuni slightly produced ; abdomen wider than hemelytra. Sp. D. dilutus, 
sp. n., SlSl, 1. c. p. 68, Caflraria. 
Tliponius, g. n., StSl, 1. c. p. 6. Allied to Homceocerus ; head callous behind 
eyes; joints 3 & 4 of rostrum of equal length. Sp. Chnex unipunctatus 
(Thunb.) and Gonocerus marginellus . Berl. ent. Zeits. 1866, p. 160. 
Anisoscelides. 
Theognis (St§,l) = Anisoscelis (Lat., Dali.). Of this genus, Ma}'r (Beise 
der Novara, ii. Hem. pp. 101-104) shortly characterizes all the species known 
to him.

Indies. 
Stenocephalides. 
Still adopts the Fabrician name Gerris in place of Leptocorisa (Latr.). 
Hem. Afr. ii. p. 87. (The type of the Fabrician genus, G. varicornis, un- 
doubtedly belongs here, but the expediency of the alteration is doubtful.)

Berl. ent. Zeits. 1866, p. 159.

long. Sp. D. trispinosa, sp. n., Stal, 1. c. p. 90, Caffraria.

Alydides. 
St§,l refers Alydus Jlavolinea, fahricii, and stalii (Sign.) and A. Jiavo- 
vittatus (St§l) to his genus Pydortus, changing the first to li.Jiavo-lineatus 
(StSl). Hem. Afr. ii. pp. 93-94.

shorter than head, slightly passing its apex ; posterior tibiae with 2 rows of 
spines. Sp. Ilypselopus dnctiventris (Germ.).
