f>. PAIUIARMONIA Beutcnmiillcr 

 (Harmonia II. Edwards, not Mulsant or Ilaswell) 



Palpi almost straight, close -sea led; antenna 1 finely pubescent below. Abdomen 

 flattened and rough-haired at sides; hind tibia 1 slightly tufted at spurs; R r , run- 

 ning to apex, hind wing with Idcv long and oblique. Hardly distinct from Conopia. 

 but with the tibia less rough; our only species easily recognized by the orange 

 under side of the abdomen. Larva 1 boring in conifers, with the skin darker than 

 the tubercles. 



1. P. pini Kellicott. Deep brown; fore wing slightly translucent; hind wing with 



scattered smoky scales; the cell and cell 1st A not specially darkened. Abdomen 



.brown above; fourth segment, above, sides, and under side mostly orange. 28 mm. 



July. Larva? boring in trunk of pine, usually in groups; a good deal of pitch 

 oozing from the borings; the larva keeping an air-hole open through the pitch. 

 Pupa in a cell in the mass of pitch. On pitch pine, white pine, and spruce.

6. CONOPIA Hiibner 



(Sesia Fabricius, in part; Trochilium Meyrick, etc., not Staudinger; 

 JUgeria- Walsingham, not Beutenmiiller, Meyrick, etc.; Synan- 

 thedon Hiibner; Pyrrhotania Grote; Carmenta Henry Edwards; 

 with Sanninoida Beutenmiiller and Ckamcesphecia Spuler) 



Palpi normal, with rather rough bristling vestiture; sometimes flattened below. 

 Abdomen with terminal tuft of male moderate, spreading fanlike, simple, bifid 

 as in Albuna. or spearhead shaped (exitiosa) ; when simple, sometimes with small 

 side-tufts; quite variable in appearance in most species, according to the state 

 of expansion, and so hardly usable for the subdivision of the genus. Hind tibia 4 

 with well-marked bristly tufts at middle and end spurs; smooth-scaled between, 

 and at base; tarsi smooth-scaled. Fore wing with R t and R, typically free (fig. 

 226), becoming concident near margin in C. tipuliformis (Chamaesphecia, fig. 227); 

 RS running to rather above the apex; hind with Idcv more transverse than 

 in Parharmonia, often short. Several attempts to divide the genus have not been 

 very successful, especially as some of the aberrant species are only known in one 

 sex. C. (Sanninoida) exitiosa is perhaps most distinct, and shows the strongest 

 se.vual dimorphism; but each sex can be closely matched elsewhere in the genus, 

 and there are no decided structural characters. Chamaesphecia represents a natural r 

 group, but many of the species have not been examined as to Rj and R 2 . 



Key to the species 

 1. Fore wing wholly fuscous. 



2. Abdomen with a single red band. 



3. Hind wing almost wholly transparent 2. rubrofascia. 



3. Hind wing with black cell, and a shade between 1st A and 2d A. 



1. exitiosa. 



2. Abdomen with one or more yellow bands 4. pyralidiformis. 



1. Fore wing fuscous, with a small hyaline spot o. sanborni. 



1. Fore wing with a larger patch, and cell also hyaline 6. rutilans. 



1. Fore wing largely hyaline, with the space below Cu hyaline.
