156 THE ENTOMOLOGIST. 
CREMNODES, Poerst. 
Stramineous, head aud apex of antenne black, apex of abdomen 
fuscous, lst segment linear (female). 1. atricapillus, 3—4 line. 
This distinct species is not uncommon in Britain. 
STIBEUTES, [oerst. 
A. Prothorax and mesothorax more or less red, legs and base of antenne 
red (females). 
a. Apex of lst segment and 2nd entirely red; aculeus rather more than 
one-fourth of abdomen. - - 1. gravenhorstii, 1% lines. 
b. 2nd and 3rd segments reddish yellow, the latter with a brown band ; 
aculeus scarcely shorter than the lst segment. 
2. bonellii, 14 line. 
B. Thorax black, abdomen chestnut-brown, lighter or darker; aculeus 
as long as the Ist segment (female). —- heinemanni, 14 line. 
The species of this genus are generally rare, and nothing is 
known of their economy. Dr. Capron has taken S. heinemanni 
at Shere (Hntom. xu. 15); only S. bonellii was included in 
Marshall’s 1870 ‘ Catalogus.’ 
AGROTHEREUTES, Loerst. 
A. Thorax red; legs nearly entirely red (females). 2. hopei, 2—3 lines. 
B. Thorax black, or almost entirely so; legs red (females). 
a. Seutellum red. - - - - 1. abbreviator, 24—24 
b. Scutellum black. - - - - : - batavus, 24

lines. 
These are probably varieties of one species; all, together with 
another doubtful species (4. destitutus, Voll.), are well figured in 
*Pinacographia’ (pl. 37, figs. 1-4); they are probably subapterous 
females of various known winged male Crypti. Marshall records 
a full-winged specimen of A. abbreviator from Corsica (Ent. Mo. 
Mag. vill. 162). Thomson says that A. abbreviator is the female 
of Cryptus pygoleucus, uniting them under the name Spilocryptus 
dispar (Opuse. Ent., p. 505); but whether he had any further 
proof than Marshall’s strong inclination is not stated (cf. Ent. 
Mo. Mag., viii. 119). Brischke says the male is Hemimachus 
albipennis, Ratz., which was bred by Siebold from a Psyche case 
(Schrift. nat. Gesell. Danzig., iv. i. 2; Iv. ili. 201). Kriech- 
baumer bred the female from Psyche fusca (calvella). A. hopei is 
the common form in Britain; it is admirably figured by Curtis 
(B. E., pl. 536). Brischke bred it from Psyche viciella,* and
