5. MUCIDUS LANIGER (Wied). 



C. Lanigcr, Wied. (" D. E." p. 9). 

 Wings limpid, the veins with alternate fuscous and white 

 scales ; their inner margin alternately banded fuscous and white ; 

 tarsal joints banded, and some joints wholly white ; tomentum 

 woolly ; thorax with a median white line ; abdomen white, with 

 a fuscous apical band on each segment. 



Although no specimens referable to the above have come to hand, 

 there can be little doubt that the species to which it refers belongs to the 

 genus Mucidus. The following is the original description. 



Entirely covered with woolly hairs, variegated with white and 

 fuscous. Length 4 lines (German). J. — Proboscis yellow, with a white 

 band at the apex ; palpi two-thirds the length of the proboscis, the 

 middle joint longer than the apical, the third shortest ; all covered with a 

 white and intermixed fuscous lanugo ; the bases of the antennaj yellow, 

 the flagella whitish ; head covered with fuscous lanugo, with a white 

 middle line ; thorax covered with fuscous lanugo, with a median stripe, 

 and two continuous stripes on the pleurae, white ; abdomen white, with a 

 fuscous^ band on the apex of each segment. Wings hnipid, the veins 

 witli fuscous and white scales, the internal margin ciliated alternately 

 fuscous and white ; haltcres whitish. The ground colour of the legs is 

 vellow but is, like tlie trunk, covered with white and fuscous lanugo ; 

 there is no white on tlie anterior tarsi, but in the hinder then- apices 

 are white ; the tibiae of the front legs are white alike at theii- bases and 

 apices, while those of the middle and hinder, are banded wliite ; the 

 femora of the front legs have three, and of the hinder and middle four 

 white bands. 



Genus IX. PANOPLITES, Theobald (Monog. I, p. 276). 



This genus is one of the best defined and most easily dis- 

 tinguished of the new genera. Once seen, there is no mistaking 

 the wing with its large regularly placed bracket-shaped scales ; 

 and the circumstance that in all the species these are disposed in
