II. Antenna; with a distinct and abrupt short club ; last 

 joint of maxillary palpi a little broader than the pre- 

 ceding, of labial palpi securiform (TmCHODEB, Herlst.) 



OPZXiO, Latreille. 



The species belonging to this genus are about forty in number, and 

 are very widely distributed, especially in the tropics ; four are found in 

 uroj>e, of which one only occurs in Britain ; its larva has been fully 

 described and figured by Waterhouse (Trans. Ent. Soc. Lond., No. 1, 

 pi. 5, fig. 1), and is also figured by Westwood (Classification, i. p. 262, 

 fig. 29, 12) ; it is of a pink colour above and pale beneath, and about 

 half an inch long, slightly narrowed in front and widened behind, 

 with the abdomen terminating in two corneous prominences ; the body 

 is covered with rufescent hairs ; according to Chapuis and Candeze the 

 meso- and metathorax and the six first abdominal segments bear four 

 spots of a bright red colour on each ; these larvae, according to West- 

 wood, are found in rotten white-thorn wood, and also in dry and decaying 

 willows, where they feed on the larvae of Anobium and other insects ; 

 the perfect insects are found under the bark; Latreille states that the 

 larvae are also met with in houses in old wood. 



O. znolliB, L. Elongate, rather depressed, with the elytra slightly 

 widened behind in the male and more plainly in the female, clothed 

 with long pale pilose hairs ; colour fuscous with an oblique spot at 

 shoulders of elytra (which is often divided, forming a spot at shoulder 

 and a longitudinal spot near suture between base and middle), a fascia 

 on each behind middle not reaching suture, and the apex, yellow ; the 

 head and thorax are testaceous in front, and are closely and coarsely 

 sculptured; head large, with eyes strongly granulated, antennae long, 

 testaceous ; thorax longer than broad, contracted behind, with a tubercle 

 on each side in front ; elytra long, with rows of strong punctures, 

 interstices with rows of distinct but small punctures ; legs testaceous, 

 with femora broadly ringed with a more or less pronounced pitchy 

 colour, apex and base light. L. 7^-10 mm. 



In rotten wood and by beating dead hedges ; occasionally at sugar ; very local, 

 and, as a rule, rare ; Kew, Richmond Park, Putney, Coombe Wood, Forest Hill 

 Darenth Wood, Chatham, Sheemess, Whitstable, Leytonstone, Brockley, Croydon, 

 Beckenham, Loughton, Barnes, Esher, Tonbridge ; Wi ndeor ; Hastings ; Llan- 

 gollen ; it appears to be chiefly confined to the London district, in which it is gene- 

 rally distributed, and sometimes not uncommon ; it is so conspicuous an insect that 

 it can hardly have been passed over in other localities. 



TARSOSTENUS, Spinola. 



In the Munich catalogue only three species are referred to as 

 belonging to this genus, but the number has since been largely added 

 to, and Mr. Gorham informs me that it is of almost universal distribu-
