T have reared a considerable number of specimens of both sexes of this interesting little insect from pieces 
of deal timber flooring infested with the larve of Anobium striatum. In June and July, 1834, I also took 
several specimens crawling about papers upon an old table much worm-eaten. 
Genus—CEROCEPHALA. 
(Westw. in Guérin, Mag. de Zool. r°* Livraison, pl. IV (1832); Walker, Ent. Mag. vol. ii. p. 148 (pars) ; Hpimacrus, 
Tbid. vol. i. p. 369.) 
This genus is closely allied to Theocolax, having, like it, a tridentate head and large triangular collar; but 
it is fully winged, and the antennz of the males are 10-jointed (pl. XXV, fig. 12). The type C. cornigera, Westw. 
(Op. cit. and Stephen’s Illustr. Brit. Ent. Mand. pl. XLV, fig. 1; Epimacrus rufus, Walker, Ent. Mag. i. p. 
149), was taken by Mr. R. Lewis on trunks of trees in St. James’s Park, London, in the Spring of 1882. iL 
also took it on palings on Wandsworth Common in July, 1835. Mr. Stephens took it near Ripley, and 
Mr. Doubleday near Epping. 
The males vary in their size as well as in the amount of development of the frontal horns. 
Sus-Fammy—PERILAMPIDES. 
Grnus—PHILOMIDES. 
(Haliday, Annales Soc. Ent. France, 4th Ser. Tom. ii. (1862), p. 115) ; Hucoptes, Westw. MS. olim.) 
‘Tarsorum unguiculi subtus dilatati, arolium inconspicuum : caput antice profunde excavatum pro receptione 
antennarum ; epistoma transversum ; gene breves subintegre ; prothorax immarginatus ; scuti mesothoraci parap- 
sides subparallele ; scutelli parasides conniventes; alarum anticarum ven normalis segmentum costale, citra 
yamum radialem ; hoe parum longius; abdomen segmento primo brevissimo annulari.’ 
The head (fig. 1 @) has a deep oval impression between the eyes in which the antenn are received when at 
rest, the large club falling upon the basal scape (pl. XX VI, fig. 14). The mandibles are acute and sickle-shaped, 
with a tooth on the inner margin towards the middle. The maxillz are terminated by an elongated lobe armed 
with strong bristles on its outer edge (fig. 1¢); the maxillary palpi are very short and apparently 4-jointed, the 
basal joint very short, the second the largest, angulated in the middle of the inner margin and bristly ; the two 
terminal joints minute. The labium is ovate, with two short 2-jointed palpi, strongly setose (fig. 1 d@). The 
tarsal ungues are denticulated on their inner edge (fig. 1 e). 
The specimen of this species now in the Museum of the Jardin des Plantes, Paris (Coll. Sichel), has the 
club of the antenne more slender, and the yellow lateral spots of the scutellum are united by a pale band across 
its base.
