114 Sir S. S. Saunders on the habits and affinities 
In importing T'yphlopone into this discussion, Walker 
loses sight of the analogy suggested by Dr. Coquerel 
(loc. cit. p. 425) as regards this ‘‘ blind ant” described by 
Professor Westwood,* which Coquerel considers allied to 
his eyeless Apocrypta and Sycocrypta ; while in the latter 
(and not in T'yphlopone) he traces a partial resemblance 
to Scleroderma with ample eyes, his Sycocrypta having 
8-jointed antenne and no palpi, with ventricose basal 
segments to the abdomen, and being also of a different 
sex as aforesaid, both being equally irreconcilable with 
Typhlopone and Dichthadia. 
When, however, among the repudiated Proctotrupide, 
already more or less corresponding with Scleroderma in 
structural details and economy, a large array of genera 
and species, including several with apterous females, 
coincides therewith in having 13-jointed antennz in both 
sexes, as described by Professor Westwood, and figured 
in three elaborate folio plates of his ‘ Thesaurus’ (xxix., 
Xxx., and xxxi.), the natural affinities of this genus with 
the aforesaid group, thus constituting the subfamily 
Epyridest proper, would seem to be incontestably 
established by these several connecting links. 
I append a description of the species which has given 
rise to these remarks, together with that of two others 
taken by me in Epirus; and of a third in the British 
Museum, recently transmitted by the Rev. Thomas Black- 
burn from the Hawauan Islands. 
Scleroderma ephippium, n. 8.

parvulo. Oculi compositi magni nigri. Ocelli obsoleti. 
Antenne flavee, capite dimidio longiores; scapo elongato 
recurvo, apice sensim largiore; articulo 2° breviore

+ The genus Bethylus, Latr. (Omalus, Jur.), has been restricted 
by Professor Westwood ‘ to the flat-headed species which have the 
hind basal cell of the fore wings shorter than the front one, and 
which have 12-jointed antennie ” (loc. cit. p. 156).
