Type material. Toxeuma fuscicornis Walker. In the BM(NH) collection there 

 is only one male in the British section, and this is clearly not an original specimen. 

 In the foreign section there is a series of 9 Walker specimens (which have been 

 remounted) standing as " Toxeuma ericae ". Since Walker later (1846 : 28) placed 

 fuscicornis as a "variety " of ericae, I conclude that the syntypes of both were com- 

 bined into one series which is represented by the 9 specimens mentioned above. 

 From the latter I designate the fourth specimen, a female, as LECTOTYPE of 

 fuscicornis. As regards ericae, only one female stands under that name in the British 

 section of the collection and it is not original material. I select as LECTOTYPE of 

 ericae the seventh specimen (a female) in the series of 9 previously mentioned. 



Gastrancistrus accia Walker. One female, designated LECTOTYPE ; it bears a 

 printed label [GASTRANCIS] " TRUS ACCIA ", also a Waterhouse label. The 

 species was placed in synonymy with Toxeuma fuscicorne Walker by Graham (1959 : 

 101). 



Miscogaster lugubris Walker (1833 : 462, <$) was placed in synonymy with Toxeuma 

 ericae by Walker himself (1846) : 28). There is now no separate label for Miscogaster 

 lugubris in Walker's collection ; probably, however, he would have placed the type 

 or types of lugubris with his series of ericae when he made the synonymy. His series 

 of ericae contains three males, which I thought might represent the missing lugubris, 

 since he described only the females of ericae and fuscicorne. Unfortunately none 

 of these three agrees well enough with the description of lugubris to be regarded as 

 its type. Possibly Walker's synonymy was wrong because the description of the 

 colour of the legs in lugubris suggests a species of Seladerma (=Telepsogos) and not a 

 Toxeuma.
