2. Base of thorax not bordered ; elytra testaocou-:, with 



a patch at apical external angles only black . . . B. EXOLETUS, Br. 

 ii. Penultimate joints of aiiteniia< moderately transverse ; 

 size smaller ; dorsal series of elytra consisting of ualy 3-6 

 punctures B. pvgm.eds, F. 



B. lunulatus, L. {africainllus, F.). Elongate aiul fusiform, shill- 

 ing testaceous red, with the head and chest black, and the elytra and 

 sixth and seventh segments of the hind body also black except the apical 

 margin and a large lunulate basal spot on each of the former, and the 

 apical portion of the sixth segment of hind body, which are light testa- 

 ceous ; head long, black, with mouth parts testaceous ; antennae about as 

 long as head and thoi'ax united, black, with the first four joints and the 

 apical joint yellow testaceous, penultimate joints about as broad as long ; 

 thorax impunctate, shining, strongly narrowed in front ; elytra a little 

 longer than thorax, smooth, with three series of large punctures (6-8 in 

 each) ; hind body with long and sparse pubescence, rather strongly, but 

 very diffusely punctured, with the ba.sal segments almost smooth ; legs 

 clear testaceous, with intermediate and posterior coxse black, lighter at 

 apex. L. 5-5| mm. 



JNIale with the seventh ventral segment of hind body smooth in the 

 centre, rather thickly punctured at sides, female with the same segment 

 very sparingly and uniformly punctured. 



In fungi J common and generally distributed throughout the kingdom. 



B. trinotatus, Er. {irimamJatus, Lac). Testaceous, with the head, 

 breast, scutellary region of elytra and a patch at apical external angles 

 black, disc of thorax often more or less infuscate ; hind body reddish or 

 fuscous red, with the base of the fifth segment more or less broadly 

 darker ; head much shorter than in the preceding species, black with 

 mouth organs testaceous ; antennoe as long as head and thorax united, 

 brownish, or ferruginous with the four or iive basal joints lighter, penul- 

 timate joints plainly longer than broad ; thorax not so strongly narrowed 

 in front as in the preceding species, base finely bordered ; elytra consider- 

 ably longer than thorax, smooth, with three longitudinal series of large 

 setigerous punctures on each, consisting of 8-12 punctures ; hind body 

 short, strongly narrowed behind, rather strongly and very sparingly punc- 

 tured, basal segments nearly smooth ; legs testaceous. L. 4^-5 mm. 



Male with the seventh ventral segment of hind body broadly impressed 

 longitudinally, with a somewhat obsolete keel before impression. 



la fungi ; common and generally distributed throughout the kingdom. 



B. exoletus, Er. (anr/tiJaris, Steph.). Very like the preceding,* but 

 distinguished by its small size, narrower form, and rather shorter head, 

 and by the absence of the scutellary dark patch on elytra ; the colour 

 of the hind body is, as a rule, lighter, and the apex is rather sharply 

 darker ; the male has the sixth ventral segment of hind body depressed 

 and smoother towards apex, the apex being slightly emarginate ; the
