Dr. A. Jefferis Turner's Observations oil 



Hmps., which is represented in the British Museum by two 

 solitary types, P. parva, Hmps., <£, from Ceylon, and 

 P. f ureal a, Hmps., 9, from Pegu. They are of somewhat 

 peculiar facies and very similar, but the former has short 

 borrect palpi, and the latter longer j^alpi curved upwards 

 in front of the frons. The tongue is absent. The antennae 

 in the <$ are shortly bipectinate to the apex, in the $ 

 simple, and the posterior tibiae have two pairs of spurs. 

 The neuration shows no areole, an unbranehed media in 

 both wings, and 7, 8, 9, 10 of fore-wings stalked. Though 

 this is structurally different from any known Cossidae, I 



will not say that it may not 

 be an aberrant genus of that 

 family. In Stygia and Inguri- 

 morpha the media is un- 

 branehed in both wings, and 

 in Lentagena the areole is so 

 small that a very small change 

 would bring about its absence, 

 and in Acyttara this has 

 actually happened. But these 

 genera are connected to the 

 typical Cossidae by allied inter- 

 mediate forms, the first be- 

 longing to a small Palaearctic, 

 the remainder to a Neotropical 

 group, while the Oriental Para- 

 cossus stands isolated. Again, 

 stalking of 10 with 7, 8, 9 

 does not occur elsewhere in the 

 family. On the other hand, 

 the neuration of Paracossus agrees well with that of the 

 Limacodidae in the unbranehed median veins as in Apoda, 

 and in the stalking of 7, 8, 9, 10 as in Susica. 



Psychidae. — This family is related to the Zygaenid group 

 by the absence of an areole and the development of a 

 median vein in both wings, as shown in the figure of the 

 neuration of Clania, which has a branched media with 

 narrow median cell in both wings. But it also presents 

 peculiar features in the anal veins of the fore-wing, 1c 

 anastomosing with 16, and la being apparently present. 

 In the hind-wing there is a short vein emitted from 8 on 

 its costal side. Whether these are peculiarities developed 

 in the family, or whether they represent some ancestral
