238 SPHINGID^E. 



Subfamily SESIIN^E. 



Roths. & Jord., 1903, p. 349 ; id., 1907, p 69 ; Jordan, 1911, p. 247. 



Imago. — " ^$. Tenth abdominal segment mesially divided, 

 often asymmetrical, the left half of the tergite and sternite 

 or the right half of the sternite being sometimes reduced, 

 vestigial, or even absent ; right and left claspers occasionally 

 also unequal ; no large friction-scales. The lower genera with 

 uniserial abdominal spines, at least on the last segments, the 

 spines all long, or long ones alternating with small ones. The 

 seventh sternite of the $ trapeziform, or sinuate, often spinose 

 at the apical edge, sometimes only laterally ; if the sternite 

 is small and triangular, and the spination of the tergite 

 multiserial, the mesonotum is prominently crested or the 

 palpus angulate laterally" (Roths. & Jord., 1903, p. 350). 



Cosmopolitan, with two tribes, Dilophonotini (not repre- 

 sented in India) and Sesiini. 



Tribe SESIINI. 

 Sesiicje, Roths. & Jord., 1903, p. 372 ; id., 1907, p. 74. 



Imago. — <£$. The moths closely resemble in outward 

 appearance carpenter-bees (Sataspes) and humble-bees 

 (Hsemorrhagia, Cephonodes), the wings being hyaline in the 

 two latter genera. "Abdominal spines not uniseriate or, if 

 uniseriate, then thorax not double- crested. End-segment of 

 antenna long or short, in the former case the mid-coxal merum 

 angulate" (Roths. & Jord., 1903, p. 372). 



Egg. — Spherical, surface smooth and shining, colour green. 



Larva. — Variable ; those of Hsemorrhagia resembling the 

 larvae of the genus Macroglossum, with round head and body 

 tapering gently frontad ; those of Cephonodes rather Acheron - 

 tiine, with rounded head and nearly cylindrical body ; those of 

 Sataspes Ambulicine, with triangular head. Surface tubercu- 

 late or with tubercles on segment 2, anal segments and horn. 

 Colour green, with longitudinal stripes in Hsemorrhagia and 

 Cephonodes ; oblique stripes in Sataspes. 



Pupa. — Tongue reaches tip of wing-case, no basal sheath. 

 Uniform reddish-brown in colour. Other characters variable. 



Habits.— The food-plants belong to the families Rubiaceae 

 (H-eemorrhagia and Cephonodes), Capri folia cese (Hsemorrhagia) 

 and Leguminosse (Sataspes), and a few other families. Pupa- 

 tion takes place in a rough cocoon on the surface, occasionally 

 just below the surface. The wings are held horizontal when 

 resting. The moths all fly by day. 



Cosmopolitan, with three India genera.
