SKRHICORNIA. 107 



II. Tarsi 5-jointed, but with the first joint covered by tho second, 

 and only risible if viewed sideways, ami tho fourth joint some- 

 times vrry small CLEKINA. 



III. Turni apparently 4-jointed, the fourth joint being very smal 



and obsolete COBYMETINA. 



TILLINA. 



This tribe is not nearly as extensive as the Clerina, and two genera 

 alone, Denopa and Tillus, are found in Europe, of winch the latter only 

 is represented in Britain ; the tarsi are plainly 5-jointed, and the 

 antennae are serrate or pectinate ; the eyes are moie or less transverse 

 and emarginate in front, and the maxillary palpi have the last joint 

 cylindrical. 



TILLUS, Olivier. 



This genus contains upwards of thirty species, which are very widely 

 distributed, occurring in North and South America, Africa, Arabia, 

 India, the Philippine Islands, and the Australian region ; five species 

 only occur in Europe, of which two are found in Britain ; they are 

 found on old timber, and occasionally on flowers. 



I. Elytra entirely black . . . . T. ELONGAIUS, L. 



II. Elytra black, with base broadly red, and a white fascia 

 on each behind middle T. UUIFASCIATUS, F. 



T. elong-atus, L. (ambulans, F., c?). Elongate, black, shining, 

 female with the thorax, except anterior margin, bright red, pubescence 

 fine, pilose ; head large, finely punctured, antennae pectinate or strongly 

 serrate, black ; thorax longer than broad, cylindrical, very finely and 

 obsoletely punctured, and sometimes transversely rugose, with sides 

 somewhat uneven and a little narrowed behind ; elytra broader than 

 thorax, with shoulders well marked, considerably dilated behind in 

 female, parallel-sided in the male, punctured in rather fine rows, 

 interstices broad, finely pilose ; legs black. L. 7-8 mm. 



The male is a very different-looking insect to the female, as the thorax 

 is black and the elytra parallel-sided ; there is often a whitish spot at 

 shoulders and just behind middle of elytra; the antennae also are more 

 strongly serrate. 



In old timber ; occasionally on elder blossom ; not common ; Camberwell, 

 D.in-ntli, Mickleham, Dulwich, Sydenham, Groydon, Tollbridge, Coombe Wood ; 

 Devon ; Swansea ; Hertford j Windsor ; Hereford ; Repton, Burton-on-Trent (one 

 specimen taken by the late Mr. W. Ourneys on his window) ; Northumberland and 

 Durham district, somewhat doubtful ; it is possible that Mr. GHrneys' specimen may 

 have been bred from old wood that had come (rum some other locality, as it has iiot 

 been recorded from any other neighbouring district. 



T. unifasciatuB, F. Elongate, parallel-sided, clothed with rather 

 long and thick black pilose pubescence, black with the base of the elytra
