DESCRIPTION OF THE LARVA OF MONOLEUCA SEMIFASCIA 



WALKER. 



(Lepidoptera; Cochlidiidas.) 



BY THE LATE CHARLES VALENTINE RlLEY. 



Larva. Somewhat resembling Euclea delphinii Boisd. Length, 

 0.60 inch. General color vermilion-red. Four prominent longitudinal 

 ridged, vermilion bands, edged or margined with yellow, from each of 

 which on every segment springs a small rounded tubercle of the same 

 vermilion color, thickly covered with short, stiff whitish bristles. On 

 segment 2 these tubercles are more conical, larger, and the bristles 

 springing from them are tipped with black. On segment 4 the lateral 

 ones are replaced by spiracles, and on segment 11 there are but two 

 such tubercles, of the same appearance, but slightly longer, and di- 

 rected in opposite directions to the dorsal ones on segment 2. Above 

 the lateral rounded tubercle on segment 10 and above the conical 

 tubercle on segment 11 are two dark-brown fuzzy patches, showing 

 relationship to Sibine stimulea Clem. Between these rows of tubercles 

 are three striped bands one dorsal and two lateral consisting each 

 of three deep blue-black lines, the central one straight, the outer ones 

 undulating, the middle of each segment within this band being flesh- 

 colored and occupied by two paler somewhat elevated spots, each 

 with a central sunken spot. Below the lateral row of tubercles is a 

 band composed of but two blue-black lines, containing the stigmata, 

 except the second pair, which are, as in the other species, placed be- 

 tween the second and third lateral tubercles. Still below these two 

 lines is a pale strip with a carneous tint. Venter, head, and thoracic 

 legs like thin glue. 



Larva from Springfield, Missouri, Septembers, 1869 (J. F. Waters).
