180 THE ENTOMOLOGIST. 



was, in both its sexes, Erythromma naias (Hansem.). Indeed, 

 when describing melanotum, De Selys perceived the danger of that 

 form being confused with immature E. naias (female), and drew 

 particular attention to the characters by which the two females 

 were to be distinguished. 



Stephens's confusion was perpetuated by Evans, and the figure 

 of Erythromma chlorkUon (female) given in 'British Libellulinse ' 

 (pi. 5, fig. 6), and stated to have been taken from a specimen in 

 Stephens's Cabinet, may be regarded as representing, though 

 very inadequately, the particular insect still in the collection. 



It appears, therefore, that the synonymy of the variety stands 

 thus : —

 Lincolnshire must now be added to the other known English 

 localities, viz. Dorset and the New Forest. Extra-British locali- 

 ties which have been given are Madrid and the Sierra Albarracin, 

 in Spain, and Corfu.

DESCKIPTIONS OF FOUR NEW SPECIES OF 

 POMPILIDA^ FROM SARAWAK, BORNEO. 



By p. Cameron. 



Pompilus lissonotus, sp. nov. 

 Black, very smooth and shining, primrose ; the antennal scape, 

 basal half of the flagellum and the under side of the fore femora dark 

 rufo-testaceous, the palpi, more than the basal third of the hind tibiae 

 behind, and the spurs, white ; wings hyaline, smoky from the base 

 of the radius to the apex ; the nervures black ; the second cubital 

 cellule oblique, of equal width ; the first abscissa of the radius is 

 almost double the length of the second, which is about one-fourth 

 longer than the third ; the first recurrent nervure is received near 

 the base, the second at the base of the apical third of the cellule. 

 The accessory nervure in the hind wings is received considerably in 

 front of the cubitus. Calcaria white, the long spur of the hinder 

 reaching close to the apex of the metatarsus. <? . Length, 4 mm. 



Kuching, Borneo, January (John Hewitt, B.A.). 

 Antennae short and thick, covered with a short pile ; the pedicel 

 longer than wide, the third joint a little shorter than the following.
