NOCTUlD/i:. — NONAGRIA. Tl 



on Verbascum thapsus, Scrophularia aquatica, and Sambucus nigra, according 

 to Ochsenheimer :— the imago is found about the middle of September.* 



Not uncommon in places where the burdock abounds ; its pre- 

 sence may be detected by the appearance of the plants, which when 

 attacked by the larvae droop and look sickly. " A\der\ey:'—Rev.

Genus CXXXVL— Nonagria, Ochsenheimer. 



Palpi nearly vertical, very thickly clothed with elongate scales on the two basal 

 joints, the terminal one exposed, with the scales rather elongated beneath ; 

 basal joint reniform, nearly horizontal, stouter than the foUowing, and above 

 half its length; the second rather elongate, straight, acuminate: the terminal 

 very short, ovate : maxillce moderate. Antenncv rather short, stout, subserrated, 

 sometimes slightly pectinated in the males, pubescent beneath : head small, 

 subtriangular, with a dense tuft of scales on the forehead : eyes large, globose, 

 naked: thorax rather stout, sHghtly crested anteriorly: abdomen elongated, 

 not very robust, with a large tuft at the apex, especially in the males : wings 

 deflexed during repose ; anterior elongate, narrow, slightly crenated on the 

 hinder margin; posterior somewhat triangular, faintly denticulate. Larva 

 fleshy, internal : pupa internal. 



The larvae of the Nonagrise, like those of the preceding genus, 

 reside within the stems of plants, and subsist upon their internal 

 substance ; but the imago differs materially from that of Gortyna, 

 especially in the form of the anterior wings, which are strongly 

 nervose, and slightly crenated; by which character they diflfer con- 

 siderably from the insects of the following genus, in which that 

 part is entire; the antennae, especially in the males, are much stouter 

 and more pilose, and the thorax is much less crested.

Head and thorax pale fuscous, sometimes with a reddish tinge; anterior wmgs 

 dull reddish-brown, with the nervures distinct and pale towards the hinder 

 margin, the discoidal one dilated and margined with deeper fuscous; at the 

 base of the wing is a deep fuscous spot, and on the disc are some irregularly 

 disposed smaller ones, with a distinct row of sHghtly elongate lineolse towards 

 the hinder margin, which latter has a series of fuscous lunular marks, m-
