220 Rev. T. A. Marshall's monograph of 



rufous or black ; 2 transverse, shorter than 3, broader than 1, with 

 two impressed oblique lines converging forwards and enclosing a 

 triangular space, smooth like the remaining segments. Terebra 

 I of the abdomen, valves somewhat incrassated, subdecurved. 

 Valvula ventralis large, a little surpassing the anus. J . Length, 

 1 ; wings, 2 J Im. 



Described from ten feraales. The form of the 1st 

 segment refers this species to the IVth Section, and dis- 

 tinguishes it from the few others that are abnormally 

 colom-ed. Typical specimens have segments 1 — 4 testa- 

 ceous, the 1st rather more rufous, and the rest black ; 

 the coxae are entirely pale. In two or three examples the 

 abdomen is dark above, and the hind or even the middle 

 coxae fuscous at the base. But several are so placed on 

 a card as to prevent their examination. 



Bred April 27th by Elisha from Lithocolletis lauteUa, 

 Zell. (five specimens) ; from L. lantancUa, Schr. (five 

 specimens) ; Jul}^ 17th, from Gracilarid semifascia, Haw. 

 (three specimens) ; and one dark coloured and in bad 

 condition, but apparently of this species, from Litho- 

 colletis carella, Zell.

Black ; palpi, sides of the abdomen, legs, squamulae, stigma, and 

 nervures, pale j-ellowish ; 4 posterior femora with a line above and 

 beneath, and tips of the hind tarsi, fiiscous; coxae also fuscous, 

 the hind pair pale at the apex. Wings hyaline. Mesothorax 

 smooth, sericeous, iridescent ; metathorax and abdomen smooth, 

 shining ; the latter compressed in the ? . Segment 1 twice as long 

 as broad, with sides parallel as far as the middle, afterwards 

 narrowed to the rounded apex ; 2 much broader than 1, with two 

 strongly impressed lines converging forwards and enclosing a sub- 

 triangular space. Terebra i abdomen, decurved; valves clavate. 

 Valvula ventralis large, triangular, but not surpassing the anus.

This species, one of the smallest of the genus, is 

 intermediate between Sections 11. and HI. ; the exserted 

 terebra refers it to the former, and the abdominal 

 structure to the latter. It most resembles hicolor, Nees. 



Taken by Haliday in autumn on the flowers of Angelica 

 sylrestris. Two females, bred by W. H. B. Fletcher, of 

 Worthing, from Lithocolletis spinicolclla, Kol., are the 

 only specimens I have seen.
