TERPNE. 217 



FAMILY BOLETOBIID.^:. 



This family has already been noticed under Dcltoides {anfea, 

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

 inappropriately be referred. 



FAMILY CHLOROCHROMID^. 



Guenee called this family Geo?)ietn'd(e, but this name cannot 

 be retained, because the true types of Geometra, Linnaeus, 

 belong to Guenee's family Etinomidce. I have therefore chosen 

 Duponchel's very appropriate name of ChlorochromidcB. 



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 

 pupa; are spun between leaves with threads.
