Hymenopterous Parasites of Coleoptera. 459 
white maggots, and another had already changed into 
a chrysalis from which he could see that it was a 
hymenopterous insect (Proctotrypes, in footnote). He 
quotes Bierkander (Communic. Bd. of Agric., vol. iv. 
p. 414), who says that six of thirty wireworms he had 
under observation were parasitised, and that “from one 
of these worms, with the loss of life of the host, six, ten, 
thirteen, to twenty guests have come out. Which 
ichneumon this is, I have not yet discovered.” 
36a. AGRIOTES LINEATUS, Linn. 
Curtis also figures (Farm Insects, pl. G, fig. 46) a larva, 
believed by him (/.¢., 198) to be that of this beetle, 
infested by Proctotrypes larvae, one of which pupated 
and protruded, accidentally he erroneously considers 
(cf. Creophilus mazillosus, ante), through the host’s skin. 
It was sent him in August, 1841, from Surrey. 
368. MALTHODES LACINIATUS, Kiesw.* 
Nees suggests (Mon. Hym., i, 243) some association 
between Telephora laciniata and his Braconid Alysia 
manducator on Hieracewm ; but the latter is now known 
to attack Diptera. 
40a, THANASIMUS. 
From an undetermined species of this genus, Ashmead 
has described a parasite under the name Tetrastichus 
thanasimt (Trans. Amer. Ent. Soc., 1894, p. 343). 
43a. PTINUS. 
Giard has given (Bull. Soc. Fr., 1898, p. 50; cf Kief., 
Proct., 1. 451 e¢ 455) an interesting account “Sur les 
Cephalonomia parasites des larves de Ptinides,” in which 
he describes a new species, C. Xambeui, whose larvae he 
found preyed gregariously to the number of fifteen or 
twenty in Ptini-cocoons. 
438. PTINUS FUR, Linn. 
For the account of parasitism of some Proctotrypid, 
which Kieffer (Proct., i, 225) supposes to belong to the
