Sphinx eremitus Hbn. 



Color chestnut brown, often marked with black; body surface pol- 

 ished, the sculpturing as in 5. kalmice; maxillary loop 9.5-10 mm. 

 long, extending nearly half the distance to the caudal margin of the 

 wings, slightly elevated from the body and touching only at its bulbous 

 tip; antennas with two indistinct rows of small tubercles along the 

 median line, these often confluent so as to form an elongate tubercle; 

 antennas of female extending half way between the distal ends of the 

 prothoracic and mesothoracic legs, those of the male a little longer; 

 metathorax with a low but distinct, carinate ridge on each side the 

 meson which extends nearly half way across the segment; scar of 

 caudal horn slightly elevated, smooth and polished, usually without a 

 concave area caudad; cremaster 3 mm. long, slender, slightly rugose 

 and ending in a smooth sharp point. Length of pupa 35-38 mm., 

 greatest width 9 mm. 



Genus Lapara Wlk. 



This genus is very closely related to Daremma as far as 

 pupal characters are concerned. It has no maxillary loop and 

 but one spiracular furrow. Normally the species of Lapara are 

 smaller than Daremma, but the individuals of approximately 

 the same size are rather hard to distinguish. The scar of the 

 caudal horn is not very distinct in Daremma, being punctate 

 as the remainder of the segment, so this very important char- 

 acter in the larva is not very helpful in the pupa, except that in 

 Daremma the characteristic depression caudad of the scar is 

 practically always present. The entire surface of the pupa 

 appears polished in Daremma with fine scattered punctures on 

 the abdominal segments. In Lapara the surface appears dull 

 and the punctures on the abdominal segments are almost 

 obscured by the impressed lines. The wings, too, are deeply 

 sculptured in Lapara, but almost smooth in Daremma. The 

 body in Lapara is typically sphingiform with the labrum always 

 on the ventral surface. There is no maxillary loop and the 

 maxillee extend nearly to the caudal margin of the wings. The 

 glazed eye-pieces are a little larger than in the members of the 

 subfamily previously studied, and the impressed line on the 

 mesal margin touches both antenna and maxilla. The antennae 

 are roughened with irregular rows of minute tubercles. The 

 swelling of the prothoracic legs, which is so noticeable in most 

 members of the subfamily, is very slight in both species of this 

 genus. The cremaster is always longer than broad and ends in a 

 sharp point. This genus includes two North American species
