264 THE entomologist's record. 



gure : l5-a-17mm. Ailes superieures d'un brun-noiratre, avec la cote 

 ocracee par places. La base est tres visiblement liinitee exterieure- 

 ment par une grande tache noire qui se fond ensuite dans la couleur 

 generale. La tache ocracee se dirige vers la cote, s'etendant en 

 point jusqu'au milieu de I'aile. A la base sur la cote, existe un 

 point noir ; au tiers de I'aile sont places obliquement deux autres 

 points noirs et en ligae avec le second plus eloigne de la base, il y a 

 quelquefois des traces d'un petit point blanc cercle de noir. Aux deux 

 tiers de I'aile, on voit a peine la trace d'une ligne foncee partant de la 

 cote et formant un angle tres aigu avant d'arriver au bord interne. 

 Le bord externa est clair et entrecoupe de points noirs. La frange, 

 en dessus et en dessous, est d'un gris obscur. Les ailes inferieures 

 sont luisantes, d'un gris fuligineux plus clair vers la base, avec la 

 frange d'un gris noiratre." Then follows the description of the body 

 and limbs, which it seems unnecessary to quote. Besides the speci- 

 men, already mentioned, from Golfe Juan, there is another very 

 typical specimen in the British Museum coll., bearing the number, 

 "698," and laltelled " S. France, Staudinger, 7.1.90." 



d. Forewings uniform pale brownish-ochreous, the inner margin at the base, 

 the last third of the costa and the hind margin dark grey. Hind marginal spots 

 black. The stigmata are normal, and there are a few minute dark scales on the 

 disc of the wing, which is otherwise entirely of the pale ground colour = ab. esterella. 

 Mill. 



One specimen in British Museum coll. labelled " South France. 

 Staudniger, 7/1/90." There is also a specimen somewhat approaching 

 this form from Constant, labelled " Golfe Juan, 8.82." This is 

 evidently the variety which Nolcken mentions {Ent. Zeit. Stettin, 1882, 

 p. 190). He says that Milliere wrote (1880) that he was about to 

 describe his peucedanella, and an aberration in which the forewings, 

 thorax, and abdomen, were " leather-yellow," instead of brown. The 

 description, given by Milliere of ab. esterella, runs as follows 

 with regard to the wings : " Ailes superieures de couleur plus ou moins 

 ocracee, saupoudrees d'ecailles noires et legerement ombrees de brunjitre 

 au dessous de la cote. L'espace basilaire de la couleur du fond est 

 limite par quelques ecailles noires. Un point a la base sur la cote, 

 deux autres obliquement au tiers de I'aile, et un point blanc cercle de 

 noir sur le disque. La frange concolore est precedee d'une serie de 

 tres petits points noirs. Les ailes inferieures sont d'un gris chaad, 

 avec la frange d'un gris obscur." Milliere states that this aberration is 

 nearly as abundant as the form described as peucedanella. 



Allieo species. — D. putridella is a very distinct species, unlike 

 any other European species that I have seen. Its rounded forewings, 

 with the veins darkly marked, and the conspicuous white discoidal 

 spot, together with the dark grey hindwings, mark it off from the 

 other species. It may, however, be useful to compare this species with 

 D. umbellana, which has the veins darkly marked, and also with Z). 

 yeatiana, which sometimes has the veins dark, and has also the white 

 discoidal spot. 



Comparison of D. putridella, Schiff., with D. umbellana, Stphs. — 

 D. umbellana is a much larger insect, with narrower forewmgs on which 

 the markings are worked out in streaks, while in the neater IK putri- 

 della, the pattern is carried out in lines and clouds. The former 

 insect measures from 20mm. -22mm. in expanse, whilst the latter 

 seldom exceeds 17mm. In D. umbellana the first discal spot of the 

 forewings is conspicuous, and the second discal small, both black.
