THE LARVA OF XANTHOPASTIS TIMAIS CRAMER 



AGAIN 



(Lepidoptera, Noctuidce) 



By HARRISON G. DYAR 



I have shown that the larva of this species varies locally to 

 a marked degree (Itis. Ins. Menstr., i, 20, 49, 1913), and I in- 

 dicated four forms from the Antilles, Dutch Guiana, Mexico, 

 and Florida, respectively. Larvae from Panama are now be- 

 fore me. A different form from any described is shown and 

 this may not be surprising ; but it is distinctly unexpected that 

 it &hould be of the Antillean insular type with large tubercles 

 and not of the continental smooth form. Such, however, is 

 the case. 



Xanthopastis timais Cramer, molinoi, new larval form. 



Head orange-red with a large black spot on each lobe at 

 seta ii ; another spot over ocelli ; bases of antennae and labrum 

 whitish. Body tubercles large and black with coarse setae ; 

 color blackish or dark gray ; cervical shield orange with large 

 black spots, one on each side of the dorsal line being especially 

 large ; anal shield almost wholly black, having only an orange 

 spot in front and slender subdorsal line on each side; body 

 with rows of pale yellow spots, appearing as a broken dorsal 

 line and more nearly continuous subdorsal one, with spots be- 

 tween and on the sides, rather indistinctly forming four trans- 

 verse rows of spots, the posterior row on each segment slightly 

 but distinctly enlarged ; leg-shields blackish.
