GEOMETRID.E. — TIMANDRA. 317 



B, Posterior tibiw of both sexes with a pair of spurs at the apex, and another 



in the middle. 

 Sp. 4. putataria. Alis dilute viridibus, strigis duabus obsoletis communibus 



albicantibus, liturdque obsoletissimd interjecto. (Exp. alar. 10 — 11 lin.) 

 Ph. Ge. putataria. Linne.—Vi. putataria. Staph. Catal. part ii. p. 153. No. 



6732. 



Wings pale green, with two common obsolete whitish strigae, the space between 

 slightly darker; the anterior incurved, the posterior a little undulated and 

 oblique; on the disc between the strigse is an obscure dark green streak: 

 cilia greenish. 



Old specimens become nearly of a clear white, with the strigae less distinct. 



Caterpillar green, with small red spots : it feeds on the birch, hornbeam, &c. : — 

 the imago is produced towards the end of May, and frequents woody places. 



Abundant near London : I have found specimens in my own 

 garden. " Scarborough." — W. Bean, Esq. " Epping." — Mr.

Genus CCXXXIX. — Timandra, Duponchel. 



Falpi moderate, porrected beyond the head, slightly squamous; the terminal 

 joint very slender and acuminated, triarticulate ; the twobasal joints of nearly 

 equal length, both slightly curved, terminal minute, ovate : maxillcE rather 

 long. Anteunw rather short, shghtly pectinated to the apex in the males, 

 simple in the females : head short, broad : eyes globose : thorax slender : 

 wings entire, slightly expanded during repose ; anterior with the apex very 

 acute, the hinder margins shghtly produced, and of the posterior projecting 

 to an acute angle ; all traversed by a diagonal fascia, arising near the apex of 

 the costa of one wing and extending to the same part of that on the opposite 

 side: body rather long and slender, tufted and obtuse in the males, acute in 

 the females: posterior tibia; in the males incrassated, compressed, and spurless ; 

 in the females slender and furnished with four spurs. Larva not tubercu- 

 lated, clavate anteriorly : pupa angular, placed in a sHght web. 



As Bradyepetes amataria evidently associates better with a pre- 

 ceding group of the Geometridse than with this genus, with which 

 it is placed by Duponchel, it became necessary to employ a 

 new term for the one that was detached ; and as I had used the 

 above for the insect already described, in allusion to its habits, 

 I have here employed the one proposed by Duponchel for the 

 entire genus, in preference to the more correct method of giving
