was, in both its sexes, Hrythromma naias (Hansem.). Indeed, 
when describing melanotum, De Selys perceived the danger of that 
form being confused with immature H. 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 Hrythromma chloridion (female) given in ‘British Libelluline’ 
(pl. 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 :—

no. 3418 (1829). 
Erythromma chloridion, Evans, Brit. Lib. p. 16, pl. 5, fig. 6 
(1845).

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.

DESCRIPTIONS OF FOUR NEW SPECIES OF 
POMPILID4Ai 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 tibiz 
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. g. Length, 4 mm. 
Kuching, Borneo, January (John Hewitt, B.A.). 
Antenne short and thick, covered with a short pile; the pedicel
