darker fuscous or fuscous red colour, upper surface very finely punctured, 

 rather dull; eyes black, very strongly enwrginate ; thorax longer than 

 broad, subcylindrical, slightly dilated at sides, rather uneven; elytra

 black or dark brown ; legs reddish-brown, with the femora strongly and 

 broadly clavate. L. 3|-5 mm. 



Male with the antennae plainly longer than the body, and the thorax 

 a third part longer than broad ; in the female the antennae are a very 

 little longer than the body, and the thorax not quite as long as in the 

 male. 



In dead twigs, in hedges, &c. ; often in old baskets and hamper* ; locally common ; 

 London district, not uncommon and widely distributed ; Dover ; Portsmouth district ; 

 Devon ; Hastings ; Bristol ; Cambridge ; Repton, Burton-on-Trent ; Suuderlaud 

 (two specimens, perhaps imported) ; not recorded from Scotland. 



OBB.ZUM, Latreille. 



Eighteen species have been described as belonging to this genus, 

 which will probably prove to be considerably more extensive; they are 

 very widely distributed, having been found in Africa, Japan, Ceylon, 

 North and South America, Tahiti, Sarawak, the Fiji Islands, Ac.; three 

 have occurred in Europe; they are rather slender and graceful insects, with 

 very large eyes and very long antennae; the thorax is considerably longer 

 than broad ; the anterior coxal cavities are closed behind, and all the 

 coxae are nearly contiguous ; the first segment of the abdomen is con- 

 siderably longer than the following ; the closed anterior coxal cavities 

 will separate our single species from all the other British members of the 

 tribe except Molorchus, from which it may be known by having the ab- 

 domen completely covered by the elytra ; the species is very rare as a 

 rule, but has been bred by Dr. Power in some numbers from aspen bark ; 

 for three years specimens came out of the same bark. 



O. cantharinum, L. (ferrugineum, F.). A very graceful and pretty 

 species ; elongate, finely pilose, with the head and thorax more shining 

 than the elytra, of a pale reddish-testaceous colour,, with the eyes black, 

 and the antennae and legs more or less blackish or brownish, the base of 

 the former, and the club of the femora of the latter being darker than 

 the remainder ; head with eyes broader than thorax, antennae very long, 

 considerably longer than the body; thorax longer than broal, dilated 

 and tuberculate at sides, almost smooth on disc, at all events in the male; 

 elytra rather depressed, irregularly and distinctly punctured; abdomen 

 with the first segment considerably longer than the second. L. 6-11 

 mm. 



Male with the first segment very long, and the second and third emar- 

 ginatc at apex and thickly pubescent. 



In anpena, apple tree*, Ac. ; very rare; Wanstead, bred in some numbers (Power) 

 , Lrytonstonr, Broxbouriie, and Brighton (Stephen*).
