one species and lacks the excurved proximal portion of the 

 maxilla. It may always be distinguished when fresh by its 

 very light brown color, and the darker alcoholic specimens are 

 readily separated by the spiracular furrows of the fifth abdom- 

 inal segment. In this genus there is one inner, deeper furrow 

 with four or five shallower interrupted furrows between it and 

 the spiracle. The body is typically sphingiform. The eye- 

 pieces differ somewhat from most of the nearly related pupee as 

 the glazed eye-piece with its median impressed line extends 

 only about two-thirds of the distance between the antenna and 

 the maxilla. The maxilla are of the usual type and extend to 

 the caudal margin of the wings. The femur of the prothoracic 

 leg is visible. The antenuce are slightly longer in the male. 

 The scar of the caudal horn is usually elevated. The cremaster 

 is triangular, longer than broad, and ends in a sharp point, 

 which may be slightly bifurcate. 



There are two species of this genus found in Eastern North 

 America, C. lineata and C. gallii. According to Rothschild 

 and Jordan, we have the subspecies C. gallii intermedia in this 

 country. The only specimen of the latter which I have seen 

 was bred by Dr. Edith M. Patch, of the Maine Agricultural 

 Experiment Station, and kindly loaned by her for this study. 

 The larva was found feeding on Galium in that state. 



The species may be separated as follows: 



a. Mandibular tubercles very prominent on the dorsal aspect of the head; head 

 pointed, the length and breadth approximately equal C. lineata 



aa. Mandibular tubercles scarcely elevated, never prominent; head blunt, the 

 breadth much greater than the length C. gallii intermedia 



Celerio lineata Fabr. (Fig. 9). 



Color usually very light brown or coffee color, often marked with 

 irregular blotches of darker brown; head, thorax and appendages 

 roughened with indeterminate transverse striations very much deeper 

 at the proximal end of the maxillae, abdominal segments deeply punctate, 

 the punctures larger along the cephalic margin and usually confluent over 

 the entire segment; labrum on the dorsal surface of the head, slightly 

 elevated adjoining the maxilte; mandibular tubercles very prominent; 

 antennse of female extending as far caudad as the prothoracic legs, 

 those of the male extending half way between the tips of the prothoracic 

 and mesothoracic legs; exposed portion of prothoracic femur about 

 2 mm. long and .5 mm. broad, the tibia prominently elevated adjacent 

 to it; spiracular furrows present only on the fifth segment, the ridges 

 between carinate, wavy and broken, extending from the inner fuiTow 

 to the spiracle; scar of caudal horn usually a slight elevation with
