well separated from the rest; II and III closely approximate; IV 

 separated from ///, but closer to /// than to V; 7 well separated from 77, 



Epistoma with seta El on a chitinous projection beyond its ante- 

 rior margin, otherwise normal. 



Frontal punctures posterior to frontal seta (Fl); distance sepa- 

 rating punctures equal to distance from Fa to Fl; distance between 

 adfrontal setae less than that betw^een Adfl and Fa; Adf2 anterior 

 to beginning of longitudinal ridge; puncture {Adfa) approximate to 

 Adf2, close to adfrontal ridge {ADFR). 



Anterior and lateral and posterior setae of epicranium crowded 

 forward on the head; Al, A2, and A3 in a slightly obtuse angle; 

 Al and A2 close together; anterior puncture Aa not discernible. 

 Lateral seta (LI) closely approximate to A3 on the level of Fa; 

 lateral puncture (La) posterior of LI, quite remote, nearly on a 

 level with incision of dorsal hind margin. Posterior setae and punc- 

 tures forward of the middle of the head; PI nearly on the level of 

 Adfl; Ph laterad of PI; P2 laterad and only slightly posterior of 

 the level of Pi; Pa approximate to LI, on the level of Adfl. 01 

 of ocellar group between ocelli 777 and IV; 02 posterior and approxi- 

 mate to ocellus IV; 03 ventrad to 02, belov/ the level of Ocelli V 

 and VI; puncture Oa between 02 and 03, approximate to the for- 

 mer, Subocellar group triangulary placed; puncture SOa closely 

 approximate to S02. 



Genal seta {Gl) antero-ventrad of the puncture {Ga). 



Labrum with anterior margin straight; no appreciable median 

 incision; lateral margins only slightly curved, converging anteriorly; 

 Lai, La2, LaS in a line on lateral edge, well forward, equidistant; 

 median setae triangularly placed nearly equidistant; M2 postero- 

 laterad of Ml, slightly forward of the level of Lai; Ml on the level 

 of La2, M3, very slightly back of the level of La3. Epipharyngeal 

 shield not clearly indicated. Epipharyngeal setae triangularly 

 grouped near anterior lateral angle of epipharynx; closely approxi- 

 mate and equidistant; slender; pomted; moderate. Epipharyngeal 

 rods with long, stout, sharply cm'ved posterior projections, 



Maxillulae with strongly spined lobes and single row of short, 

 rounded blades (fig. 64) similar to those in the Sesiidae, ^ 



Pwpa.—i^A. 12, figs. 77, 78, 79.) Elongate; moderate; maxillae 

 triangular, nearly as broad as long, without lateral projections 

 adhering to them on dehiscence; maxillary palpi present^; antennae

« Miss Mosher (Bull. 111. State Lab., vol. 12, art. 2, pp. 30, 38, 41) gives among other characters for her 

 Cossoidca, the absence of maxillary palpi. There are, however, in Givira and Cossula which resembles it 

 in most pupal characters, small triangular areas along the cephalic margins of the prothoracic legs and 

 directly caudad of the eye pieces which it is difficult to interpret as anything else, particularly as they sepa- 

 rate completely from the maxillae on dehiscence. Like many another character, the presence or absence 

 of maxillary palpi in the pupa is probably of no more than generic significance.
