348 LoTigicornia Malayana. 



between them ; together they form a narrow, parallel, somewhat 

 quadrangular organ, the two lobes of the lip united, and at their 

 junction presenting a strongly-marked keel or rib. The labial 

 palpi arise from two deep approximate depressions nearly mid- 

 way, which may perhaps be taken as the line between the mentum 

 and labium.* It may be also remarked that the anterior coxse in 

 the more typical genera are globose, passing only a little beyond 

 their cotyloid cavities. 



Except Ecphora, which is limited to a single species, the whole 

 of this family are either Malayan or Indian, not many, however, 

 extending beyond the former region. They are generally found 

 flying or rather " floating slowly" over newly fallen timber. Te- 

 Iraopes, an American genus, sometimes referred to this sub- 

 family on account of its divided eyes, I regard as a member of 

 the Ainphionycliince.
