THE REAL LARVA OF XANTHOPASTIS TIMAIS 



CRAMER. 



By Harrison G. Dyar. 



A little while ago I described in this Journal (Vol. X, p. 125) a 

 larva from Florida under the name of timais. Since then Mr. E. A. 

 Schwarz has found larvae in Cuba which he has bred, and he brings 

 me a specimen in alcohol which he assures me is the true larva of the 

 species. It is not like the larva described by me, except in a super- 

 ficial way, and I therefore publish the following in correction. What 

 the larva is that I described has not yet been ascertained. 



Larva. — Head rounded, slightly wider than high, scarcely bilobed ; 

 setae coarse, black ; light red, a round black spot on seta ii and one 

 over eye, jaws black-lined. Body cylindrical, subequal, joint 12- 

 scarcely enlarged, feet normal, equal. Cervical shield, bases of tho- 

 racic feet, abdominal feet and bases, posterior half of joint 12 and all 

 the ground color of 13, light red. Venter pale ; rest of body black, 

 spotted with white. Cervical shield with black spots on the tuber- 

 cles ; setae large and coarse ; tubercles large, somewhat elevated, 

 black. The white spots consist of three transverse rows per segment,, 

 the two anterior rows of small spots, the posterior row of larger spots, 

 in the positions of the usual lines, dorsal, subdorsal, suprastigmatal, 

 substigmatal and one at tubercle vi. Tubercle iv at the center of the 

 spiracle. Three black spots on the leg base at the setae ; claspers 

 black ; joints 12 and 13 heavily black-spotted at the tubercles. Spir- 

 acles black, that of joint 2 with white posterior border. Width of 

 head 3.2 mm. 



The larva described by me differs in the tubercles being obscure 

 and reduced, the setje fine and short ; the head is higher and the black 

 spot on it is in a different place , the cervical shield is uncornified and 

 is black with some red in the neck only ; the distribution of the whit- 

 ish marks on the body is very different and the red color at the anal 

 end is less extensive and not spotted by black tubercles.
