TERPNE. 217 



FAMILY BOLETOBIID^;. 



This family has already been noticed under Deltoides (antea, 

 p. 193), to which Guenee himself suggested that it might not 

 inappropriately be referred. 



FAMILY CHLOROCHROMID^E. 



Guene'e called this family Geometridce, but this name cannot 

 be retained, because the true types of Geometry Linnaeus, 

 belong to GueneVs family Ennomidce. I have therefore chosen 

 Duponchel's very appropriate name of Chlorochromida. 



The antennae are generally more or less pectinated in the 

 male ; the palpi and proboscis are slender ; the abdomen some- 

 times crested ; and the hind tibiae sometimes provided with a 

 single pair of spurs. The wings are generally rounded and 

 entire (rarely dentated or angulated), smoothly scaled, and of 

 a green colour, with transverse lines. 



The larvae are more or less rugose, with two small points on 

 the head, neck, and at the extremity of the abdomen. The 

 pupae are spun between leaves with threads.
