Aleyrodes rubicola (Douglas).—Certainly not rare, but local 
near Birtley.

A PUZZLE IN THE NOMENCLATURE OF THE HYMEN- 
OPTEROUS FAMILY STEPHANIDA, Leacu. 
By E. A. Exuiorr, F.E.S., F.Z:8. 
I sHaut be glad of a solution of the following puzzle. 
The genus Fanatopus was erected by Smith (‘Journ. Proc. Lin. 
Soc.’ v, p. 58, 1861), and a species, ruficeps, described. In 1887, 
Cameron (‘ Biol. Cent. Amer.’ Hym. i, p. 420) described Megischus 
ruficeps, and finally, in 1904, Saussure (‘ Mission Pavie,’ iii, 
p- 201) describes another Megischus ruficeps. Megischus is an 
acknowledged synonym of Stephanus. 
In 1889, Schletterer in his Monograph on the genus Stephanus 
(‘ Berl. Ent. Zeit.’ xxxiii) states that, since the genus F'ewnatopus 
was withdrawn as synonymous with Stephanus, the name ruficeps 
is preoccupied by Smith, and he renames Cameron’s species, 
capitatus. In the same monograph he makes Smith’s ruficeps 
synonymous with Stephanus indicus, Westw. (1841). Further, 
W. A. Schulz (‘ Berl. Ent. Zeit.’ li, p. 322) renames Saussure’s 
ruficeps, on the ground of the name being preoccupied by 
Cameron! He calls it Sausswrei. 
The genus Stephanus has since been subdivided. Fanatopus 
has been rightly revived, but F’. ruficeps, Smith, falls, being a 
synonym of Fenat. indicus, Westw. 
Meg. ruficeps, Cam. = capitatus, Schlett, appears to be a 
Parastephanellus or Hemistephanus, while Meg. ruficeps Sauss. = 
Saussurei Schulz, is a genuine Stephanus. 
What are the correct names of the two latter species ?

touching the above matter. I have no doubt Sir Edward Coke
