44 HETEROMERA. 



is brownish-black or brownish, but varies, and is sometimes testaceous 

 brown ; a patch near apex and a common band before middle are 

 obscurely testaceous and lighter than the rest of the elytra, but are often 

 more or less obsolete ; legs brownish or reddish-testaceous with the 

 i'emora darker. L. 2-2f mm. 



Under bark of decayed trees; rare; it has hitherto only been found in Scotland 

 in the Dee and Moiay districts ; Mr. Champion has taken it in some numbers at 

 Aviemore. 



A. flexuosa, Payk. Elongate, less parallel than the preceding 

 species, dull, very finely and subrugosely punctured, clothed with fine 

 silky pubescence, of a bright reddish-yellow colour with a broader or 

 narrower band across disc of thorax, and two common waved bands across 

 elytra (of which the front one is the narrower) black; head black, 

 antennae rather long and moderately stout, dark, with base and apex 

 yellow ; thorax slightly transverse, narrowed in front, with a slight 

 central channel and a small fovea on each side at base ; elytra about as 

 broad at base as base of thorax, with sides slightly rounded; legs yellow, 

 or reddish-yellow. L. 3-3^ mm. 



In boleti, especially on alders and sometimes willows ; very local and, as a rule, 

 rare; Cambridge and Peterborough (Stephens) ; Hampshire (Mouerieff) ; Scar- 

 borough (Lawson) ; Tet-sdale (Blatch) ; North muberliUid and Durham district, " In 

 Polyporus radiatus growing on alder, near VVoolur," Mr. T. Hardy ; Scotland, in 

 P. radiatus on alder, rare, Sol way, Tay, and Moray districts ; it occasionally occurs in 

 numbers when found. 



PHXiCEOTRYA, Stephens. (Dirc&a, F., sec. auct.) 



Three species are contained in this genus, two of which occur in 

 Europe,* and one has been desmibed from Brazil; our single British 

 species is a long and rather a large insect, although it varies considerably 

 in size ; the maxillary palpi are somewhat serrate, with the last joint 

 elongate-securiform ; the aiitennre are filiform, with the third joint quite 

 twice as long as the second, which is short ; the prosternum is very short 

 before the anterior coxae ; the thorax is longer than broad, with the 

 front produced and rounded, and the elytra are elongate ; the inter- 

 mediate coxae are not contiguous ; the legs are slender with small, but 

 distinct, tibial spurs, and the penultimate joint of the tarsi is bilobed. 



The larva of P. rufipes is described by Westwood (Classification, i. p. 307) ; it is 

 whitish, elongate, and scaly, convex and thickest at the middle and tail ; the head is 

 semiglobose, with short 3-joiuted autennfe ; anterior legs large, posterior pairs much 

 smaller ; last segment furnished with two sharp horny appendages, curved upwards ; 

 this larva bores into the solid wood of old oak, in which the perfect insect is also 

 found. 



P. rufipes, Gyll. (Stephensi, Duv.; tenuis, Hampe ; Dirccea 



* The second European species, P. Vatiduueri, Mu!s., appears to be considered by 

 porno authors as synonymous with P. rujijjes.
