Tenehrioides.] clavicornia. 2G9 



tributod l>y commerce over a great poiiion of the world; it has usually 

 been referred to Trof/osita, 01., but as the type of Olivier's genus appears 

 to be Teninochila ccerulea, the latter insect is now referred to Trogosita, 

 and the name Tenehrioides is substituted for the old genus Trognsita. 



Tlie larva of T. maiiritanicus is fully described by Ericbson (Naturgosiclite dcr 

 Ins. Deutsch. iii., p. 243), and is also described and figured by Westwood, Classif. 

 i. l-i7 ; it is rather loug and cylindrical, narrowed towards the head, and furnished 

 with long setas at sides; the head is small, jiitcliy, with short antenna?; the pro- 

 thorax has a rather broad dark scutum (which appears sometimes at all events to be 

 divided), and the meso- and nietathorax are both furnished with two small jiitchy 

 scuta, one on each side ; the last abdominal segment is pitchy, and bears two rather 

 strong conical spines ; the general colour is dirty white. 



This larva feeds upon stored grain, and sometimes does a very serious 

 amount of damage in granaries ; it also attacks bread, nuts, and almonds, 

 and sometimes is found in dead trees ; according to Curtis it is very 

 destructive in the South of France (where it is called " Caddie "), as it 

 eats the outside of the grain, and passing from one to another injures 

 more than it consumes. 



T. mauritanicus, L. (carahoides, F.). Black or pitchy-black, 

 sometimes pitchy-red, oblong, depressed ; head narrower than thorax, 

 rather sjxaringly and strongly punctured ; antennoB with a 3-joiiited, 

 but not very strongly marked, club ; thorax transverse, narrowed behind, 

 strongly margined, anterior angles considerably projecting, posterior 

 angles right angles forming a tooth, disc more sparingly, sides rather 

 more thickly, punctured ; scutellum impunctate ; elytra with sides slightly 

 rounded, with distinct striaj, which are rather obsoletely punctured, 

 interstices finely punctured and irregularly striated transversely ; legs 

 ferruginous. L. 6-10 mm. 



In warehouses, bakers' shops, granaries, &c. ; not uncommon and generally dis- 

 tributed throughout the kingdom ; au imported species. 



PELTINA. 



The insects belonging to this tribe are oval or round and very 

 convex, with a flattened margin ; in our single genus Thynndus and also 

 in Pelt is the anterior coxal cavities are open behind; 2\ Hmbati/s 

 closely resembles a Cassida in general appearance, and at first siglit 

 appears to be as different from Nemosoma as any insect could well be. 



TK-STMAXiUS, Latreille. 



This genus contains one species from North America, and one which 

 is somewhat widely distributed in Europe. 



The larva of T. ?««tfl/«.s is described and figured by Chapuis and Candcze (Les 

 Larves des Coleopteres, p. 77, pi. ii., fig. 6) ; it is rather broad aud stout, D-IO niui.
