BOMBYCTDM. 13 



Genus 4. CLISIOCAMPA. 



Antennae rather short, stoutly pectinated in the male, 

 slightly so in the female ; thorax broad, abdomen short and 

 not tufted, thick and pointed in the female ; wings rather 

 short, the hind very broad, all densely clothed with scales. 



The two species are very similar, but can at once be 

 distinguished by the form of the first transverse line — which 

 in G. neustria crosses the wing, but in C. castrcnsis curves in, 

 to the base. 



1. C. neustria, L. — Expanse of male 1^ to If inch, of 

 female 1^ to If. 



Dull red-brown or buff ; fore wings with a broad regular 

 central band. 



Antennae of the male rather short and somewhat recurved 

 beyond the middle, strongly pectinated with long curved teeth ; 

 shaft thick, but tapering to a point ; entirely brown ; head 

 tufted, red-brown. Thorax stout, abdomen tapering and 

 rather short, both densely clothed with long, loosely-disposed 

 scales. Fore wings short and broad, somewhat triangular, 

 with the costal margin nearly straight ; apex angulated • 

 hind margin very gently curved in a long sweep round the 

 anal angle and dorsal margin. Hind wiugs rounded behind 

 and with the anterior margin strongly arched near the base, 

 so that in repose it projects distinctly in front of the fore 

 wings. Head, thorax, abdomen and wings uniformly yellow- 

 buff, yellow-brown, umbreous, chocolate, or red-brown ; fore- 

 wings with both first and second lines rather curved and 

 sinuous, and more or less parallel, dark-brown or red-brown, 

 but in the darker specimens often edged outwardly with buff 

 so as to give the impression that the lines are of that colour • 

 cilia usually yellowish, irregularly spotted or blotched with 

 chocolate, but in the darkest forms wholly red-brown. Hind 

 wings often without markings, otherwise with a central 

 cloudy transverse brown line or shade coincident with the
