Lo. pallidiis. Kiug.—Steph. Catal. 327. A'o. 3775. 



Male ovate-depressed, black, with the abdomen red beneath; legs pale; 

 antennae shorter than the thorax, lanceolate, with 18 rays on each side. 

 Female pale yellowish; thorax with about 3 dorsal bbick spots; abdomen 

 with brownish fascise; antennae with 18 joints, the basal ones lutescent. 

 Taken in the larva state by Dr. Leach near Oban, in Scotland, 



and reared in June : also found by A. Cooper, Esq. near Cobham, in 



Surrey. 



§ 4. AnleniicB 9-jointed, moderate or elongated ; anterior wings with 1 marginal 

 and 3 — 4 submarginal areolets ; liody short. 



Genus X.— CLADIUS, Leach. 



Antennas with the 2 basal joints straight and short, the rest obliquely inserted, 

 pilose in the males, and occasionally furnished with an elongate process on 

 one side, giving a branched appearance ; in the females simple and slightly 

 pilose: mandibles unidentate : head transverse: ocelli 3: wings ample; 

 anterior with 1 large marginal areolet, and 3 distinct submarginal ones, the 

 2nd short, and receiving a recurrent nervure in the middle, the 1st in some 

 species obscurely subdivided by a very indistinct nervure, producing the 

 appearance of 4 areolets : legs simple : tibia all with only a pair of spurs at 

 the apex. Larva with 18 prolegs. 



Altliough some of the species of this genus closely approximate to 

 those of the 2 following genera, the difference in the structure of the 

 antennae, which, however, vary slightly in the species, and conse- 

 quently require a division in the genus, exclusively of the variation 

 in the neuration of the anterior wings, will sufficiently enable the 

 reader to distinguish them, the antennae being pilose in both sexes, 

 and in all the males the 3rd joint is more or less eccentric ; in the 

 typical species that and the 3 following being all so constructed.

 Te. Juniperi. Linne.—Turton {l)—Steph. Catal. 328. No. 3776, note. 

 Shining black, with the tibiae and tarsi pale; antennae 16-jointed in the female, 



and testaceous ; in the male with a series of pectinations, the apex simple, 



obtuse. 

 Turton indicates this as British, but I presume without authority, as I hare 



never seen an indigenous specimen.
