324 [April 



Head larger, more prominent than in the allied species, whitish be- 

 tween the eyes; maxillre well developed; palpi long, erect, applied 

 against the front, third article long, entirely visible above the head ; 

 antennae long; thorax stout, pale brownish, sides of tegular and meta- 

 thorax whitish ; abdomen very slender, exceeding the posterior wings, 

 very pale brownish, whitish beneath, slightly crested on second basal 

 segment. S . Exp. 1.20 inch.

Dy far the most prominently marked species of the genus. Differs 

 strongly from its congeners by the long erect palpi, the distended hu- 

 meral spot which crowds the transverse lines towards the external mar- 

 gin and the large punctate sub-metallic space on internal margin ; the 

 undersurface shows no sub-apical demi-line as in L. Doubledayi G-uenee, 

 which L.formosa resembles in the straight costal margin. This spe- 

 cies of Guenee's appears to vary from brown to blackish in the darker 

 shades of the anterior wings. 



GORTYNA. Ochsenheiiner. 



Guenee, speaking of his Gortyna rutila, says : " (''est probablement 

 cette espece que Duponchel dit si voisine de la Flavago dans son sup- 

 plement," Noct. 1, p. 123. Harris, in describing his Gortyna leucos- 

 tigma, says, ''The moth closely resembles the Gortyna flavago of Eu- 

 rope, but is sufficiently distinct from it." 



The coincidence of the above remarks, I not having seen the Euro- 

 pean species, together with Dr. Harris' short description and his ex- 

 pression " white spot," in referring to certain spots on the anterior wings, 

 made me believe (Proc. Ent. Soc. Philad.. Vol. 2, p. 432) that the de- 

 scriptions referred to the same species which I have frequently met 

 with and which is very recognisably figured by Guenee. Since seeing 

 a European specimen of G. flavago W-V., which I have unfortunately 

 not been able to retain for comparison, I find that Dr. Harris undoubt- 

 edly intended G. cataphracta Grote. or a species nearly allied to it. 

 since the latter species resembles the European G. flavago very closely, 

 though it is I think distinct. Since I find that Dr. Herrich-Sch;effer 

 records a Eui'opean Gortyna leucostigma, referred by Gueuee and 

 Walker also to the genera Hydrozciq and Apamea, the name proposed 

 by Dr. Harris cannot fail to cause confusion, and in the additional un- 

 certainty of the species intended had better give way to the subsequent 

 name proposed by myself. There is a second undescribed species allied 

 to G. cataphracta m. and differing chiefly in the straight transverse 

 posterior line.
