Semiotellus diversus (Walker) 



Semiotus clarus Walker, 1834 : 291, $ [nee <£]. 

 Semiotus tarsalis Walker, 1834 : 292, $ [nec^]. 

 Semiotus diversus Walker, 1834 : 294, <$ $. 



Type material. Semiotus diversus Walker. BM(NH), British section of the 

 collection, 1 $ which is probably not original material ; foreign section, 3 $ and 2 <$, 

 all bearing Waterhouse labels. From the latter series I designate a female as 

 LECTOTYPE. 



Walker's series of both clarus and tarsalis are mixed, the females being the same as 

 diversus, whilst the males belong to mundus. Their respective males on the whole 

 agree best with his descriptions, hence lectotypes of that sex have been selected. This 

 leaves diversus as the valid name for the present species. 



Britain (rather uncommon) ; Sweden. 



Biology. Unknown. Imagines chiefly in June (some records for Aug.-Sept.).

Semiotellus mundus (Walker) ; Peck et al., 1964 : 33. 



Type material. Semiotus mundus Walker. A female standing in the British 

 collection in the BM(NH) is clearly not the type. In the foreign section there is 

 a male which has been misplaced ; it is designated LECTOTYPE and is labelled 

 " Semiotus mundus Walk. Type $. G. J. Kerrich det. 1958 ". 



Semiotus clarus Walker. Five specimens (one a Eulophid !). LECTOTYPE, 

 the third, a male. 



Semiotus tarsalis Walker. One $ and 7^ (but two probably not original material). 

 LECTOTYPE, the fifth, a male. 



Semiotus scoticus Walker. One female, LECTOTYPE ; it bears a printed label 

 " Scoticus W.". 



Semiotus varians Walker. In the British section of the BM(NH) collection there 

 are 3 <$, two of which are not original material, whilst the third disagrees with the 

 description. In the foreign section of the collection there are 14 specimens which 

 I regard as syntypes (4 $, 10 <$). From these I select the first female as LECTO-
