Forest ; York ; Duuham Park, Manchester ; uot recorded from the extreme northern 

 counties of Enghmd or from Scothiud. 



TXXIXISXAS, Stephens (Ctesias, Steph. 111.). 



Tliis crenus contains one European species, which is distinguished from 

 Meqatama by the broader mesosternum, the more widely separated in- 

 termediate coxaj, the longer first joint of the tarsi, and the serrate club 

 of the antennae in male. 



The lirva of T ^erra is very peculiar ; it is figured by Westwood (Classific. p. 156, 

 fio- 14 18) and by Chapuis et Candcze (Larves des Coleopteres, PI. ni. fig. 2) ; it is 

 feVrucriuous and do'thed willi lo>ig brown hairs, and is broad in frontand narrowed behind, 

 and terminated by a long tail of hairs as m AUagenu, ; the clnet peculiarity hes 

 however, in the tufts of liairs tliat are arranged closely on the hist four seginents of 

 the abdomen, which the larva has the power of raiding at will ; these give the apex 

 of the body a fan-like appearance, with the long tuft of hairs at apex pr..jccting in the 

 middle • the larva of Megatoyna appears to resemble that of Tiresias, and the larvse ot 

 the Anthreni are also furnished with the same tufts of hairs at sides. 



The larva of Tiresias is found much more commonly than the perfect insect in 

 localities where the latter occurs ; it lives under bark of elm, willow, oak, &c., and 

 may easily be reared. 



T serra, F. Subovate, rather broad, moderately convex, but with the 

 elytra somewhat depressed on disc, black, shining, immature specimens 

 beiiKr pitchy-brown; head much narrower than thorax, eyes prominent, an- 

 tennle reddish ; thorax transverse, slightly reddish at sides, much narrowed 

 in front, strongly sinuate and produced in middle at base, with disc very 

 finely and diffusely punctured, the punctuation being more evident at 

 sides • elvtra closely and finely, although distinctly and somewhat 

 asperatel/, punctured ; legs lighter or darker reddish-testaceous with the 



femora fuscous. L. 3|-5| mm. , p , -.i, 



Male with the clab of antennae very large, plainly serrate, female with 

 the club smaller, not very strongly marked, cylindrical. 



Under loose dry bark of elm, oak, willow, &c ; local and not common ; Forest 

 Hill, Putney, Coydou, Norwood, Richmond Park, Cla.ygate Enfiehl, Sheerness, 

 Greenwich, &c. ; New Forest; Devon; Norfolk; Evesham; Montgomery; Kipon; 

 Dunham Park, Manchester; not recorded from the extreme northern counties of 

 England, or from Scotland or Ireland, but it probably occurs in the latter country. 



ANTHRENUS, Geoffroy. 



This genus contains between thirty and forty species, which are 

 verv widely distributed, some being almost cosmopolitan, as they 

 are exceedingly destructive to all zoological collections, and are therefore 

 carried from one part of the world to the other in the specimens and 

 boxes • the four IS'orth American species, for instance, are all represented 

 in Britain: the Anthreni are small round or broadly ovate insects, of a 

 dark colour, but covered with more or less variegnted scales ; the head
