Black : mouth yellow ; antennae slender, porrect, dusky-black, paler at the 

 base, with the l^th and 13th joints white above ; thorax with a white dot 

 on each side beneath the wings> and another at the base before them ; 

 abdomen rather slender, acute at the apex, with the margins of all the 

 segments chestnut; legs including coxae and trochanters, pale red, the 

 posterior tarsi with the base of the joints paler ; wings hyaline, costa and 

 stigma black, scales yellow. 

 Taken near London, in July, but rarely ; also, I believe, near 



Andover. 



Sp. 29. annulator. Niger, femoribus tibiisque rujis, his extra albis, annulo 

 antennarum albo, abdominefusco, aut rufo aut badio. (Long. corp. 2 — 4^ lin. ; 

 Exp. Alar. 5— 7^ lin.)

Black : labrum and middle of the mandibles, and often the clypeus, ferru- 

 ginous ; palpi fuscous, paler at the tip ; apex of the scutellum and a dot 

 beneath the wings frequently chestnut ; abdomen variable, orate, brown- 

 black, with the extreme margins of the segments sometimes chestnut, or the 

 entire surface chestnut, or bright red, with all intermediate shades ; legs 

 rather short, red, with black coxae and trochanters, sometimes red or 

 chestnut beneath; posterior femora with the apex occasionally dusky; 

 4 anterior tibiae with a white dot in the middle ; posterior ferruginous 

 beneath, with the apex blackish, the middle portion white without, tarsi 

 fuscescent ; antennae filiform, involuted, 1st joint black, sometimes red 

 beneath, the following fuscous, with the 8th to 14th more or less white, with 

 a fuscous dot beneath; wings subhyaline, stigma and costa generally dull 

 ferruginous, scales fuscous, or yellowish.

Of this variable insect, all the variations of which are females, I suspect Ic. 

 fabricator (which is almost equally variable, and of which only the males 

 are known) to be the opposite sex. 



Extremely abundant, in gardens, woods, &c. throughout the 

 metropolitan district, in June: frequent also in Salop, the New- 

 Forest, Norfolk, &c. 



Sp. 30. tibiator. Niger, femoribus anticis pro parte riifis, tibiis anticis ruJiSy 

 posterioribus extra albis. (Long. corp. 2\ lin.; Exp. Alar. 4^ lin.)
