7. THOMISOIDES UTRIFORMIS, n.sp. (Plate XIII. figs. 4, 4°, 
4°, 4°.) ° 
Cephalothorax cordiform, truncate in front (the caput nearly 
straight at the sides), orange-tawny, pilose, with marginal and radi- 
ating lines of short black sets; eyes pale olive-hyaline, the central 
pair close together on the centre of the anterior margin of the caput, 
lateral pairs tolerably wide apart, placed on the lateral anterior 
margins of the caput, slightly obliquely ; abdomen trapezoidal, ex- 
cavated in front, transversely wrinkled and bisinuate behind, pilose, 
sordid ochraceous, clothed in front with coarse black sete, a series 
of depressions on each side; legs testaceous, banded with grey, 
with longitudinal series of short black setze; palpi testaceous, setose ; 
falces castaneous, setose ; maxillze and labrum castaneous ; pectoral 
plate testaceous, circular, slightly truncated in front and behind; 
abdomen below olive-brown, paler at base. Length 9 millims. ; re- 
lative length of legs 2, 1, 3, 4. 
One specimen, Charles Island. 
Most like T. rubripes of Nicolet. 
VII. Coxeorrera. By C. Warernovse. 
GEODEPHAGA. 
SELENOPHORUS GALAPAGOENSIS, G. R. Waterh. 
The type of this species, found by Mr. Darwin and described as 
** piceus,”’ is evidently immature, as the two specimens just received 
from Commander Cookson (unfortunately also both females) are 
almost black above, but very slightly neous when viewed obliquely. 
The larger specimen measures 44 lines. 
Hab. Charles Island (Darwin and Cookson). 
HyDRADEPHAGA. 
EUNECTES OCCIDENTALIS, Er. 
Six examples, which agree very well with the brief description of 
this species. 
Hab. Charles Island (Cookson). 
Actutius 1nctsus, Aubé, var. 
Three examples. The male agrees perfectly with that of A. in- 
cisus. The female differs in having the thorax more punctured, and 
in having the elongate punctures on the elytra much stronger and 
more close than in any examples of zncisus; and the punctures, 
although diminishing in strength and density, extend nearly to the 
apex. 
ve considerable difference is admitted to exist in this respect in 
A. circumscriptus, the specimens from Galapagos must, I think, be 
considered mere varieties of 4. incisus.
