margins, a broad central macular fascia and lateral margins (gradually widening from base) to corium, 
and disk of cuneus, either dark brown or blackish. Antenne black, the base of first joint and the apex 
of the second ochraceous, the second obscurely annulated with castaneous near base. Legs pale ochra- 
ceous, anterior femora longitudinally streaked above and the intermediate and posterior femora somewhat 
obscurely annulated with fuscous near apices; tibie with basal, central, and apical fuscous annulations ; 
tarsi fuscous, the claws ochraceous. Membrane pale fuscous, the cellular areas and a subapical spot and 
apical margins dark fuscous. Body beneath apparently (carded specimen) ochraceous with some brownish 
markings.

VALDASUS. 
Valdasus, Stal, Rio Jan. Hem. i. p. 56 (1858) ; Walk. Cat. Het. vi. p. 47 (1873). 
This peculiar and well-marked genus is easily recognized by the vertically deflexed 
head in front of the eyes, which are very prominent, obliquely suberect, and contiguous 
to the anterior margin of the pronotum. 
Valdasus appears to be quite confined to the Neotropical Region. Only two species 
have hitherto been described, one from South Brazil and the other from Mexico. Of 
these the last is found in our tauna, and seven other new species are here described. 
There is therefore every probability that this will eventually be found to be a most 
extensive genus. 
These insects were found by Mr. Champion on black fungi (to which they assimilated 
in colour) attached to fallen trees. ‘They were of particularly active habits, both flying 
and running, thus making their capture somewhat difficult. 
1. Valdasus famularis. (Tab. XXIV. fig. 7.) 
Valdasus famularis, Stal, Stett. ent. Zeit. xxiii. p. 321. 251°. 
Hab. Mexico!. 
The type in the collection of Dr. Signoret is here figured. 
2. Valdasus stellatus, n. sp. | 
Closely allied to V. famularis, but differing by its darker colour above; pronotum with three linear, longi- 
tudinal, pale ochraceous lines, one central and two submarginal; femora much darker than in Stal’s 
species, and not doubly annulated, but with a single upper ochraceous spot. It structurally differs by 
having the lateral pronotal angles distinctly subnodulose, and narrowly ochraceous at their apices. 
Long. 6—7 millim. 
Hab. Guatemata, San Juan in Vera Paz and Cubilguitz (Champion). 
Two specimens, one from each of the above localities, were collected by Mr. Cham- 
pion, and these vary in size as above described. : 
3. Valdasus marginicollis, n. sp. 
Body above black ; lateral margins of the pronotum, two central spots near base of scutellum and apex of 
a narrow linear fascia commencing at basal margin of corium extending through about half its
