Note : — Certain of the Wailuku species in this collection 

 might well be included together with those of lao Valley for 

 the purposes of this exhibit, some having been as a matter of 

 fact taken in both places by previous collectors (See Proc. Haw. 

 Ent Soc, Vol. I, pt. 3, p. 86). I have separated the distribu- 

 tion of the species in the present exhibit in order to show differ- 

 ence in elevation of the collecting ground and also because cer- 

 tain of the lao Valley species proper are recorded only as taken 

 from the higher elevation. 



A Note on a Cimicid Hemipteron with deformed head, ?nd on a 

 Membracid with deformed pronotum. 



BY G. W. KIRKALDY. 



(Presented by O. H. Swezey. Specimens exhibited). 



Deformed antennae and legs are not of unusual occurrence 

 in certain families of Heteroptera, especially in Coreidae and 

 ^iyodochidae, these being due in many cases to injuries received 

 in nymph-hood. Similar abnormalities in head and pronotum 

 are not so common, and 1 therefore place two on record. 



The first is a curiously deformed head of a female Phyllo- 

 cephaline Cimicid, Mcgarrhamphus Jiastafus, from Java, col- 

 lected by Mr. Muir. In the normal condition of the head viewed 

 from above (fig. i), the juga are very much elongate, the tylus 

 being very short and closed around in front by them. In this 

 deformed specimen, the whole head is shortened, the juga are 

 a little crumpled, much misshapen, the right jugum being round- 

 ed, shortened, and swollen apically (fig. 2).

normal head ; 



2. The same abnormal. 



One of the characteristics of a typical Membracid Homop- 

 teron is the possession of an elongate process of the pronotum, 

 which lies more or less flat along the back. I now exhibit a 

 specimen of a species of Centrotypus collected by Mr. Muir at 

 Parit Buntar, in the Malay Peninsula, which has this process 

 crumpled and much shortened, the main part of the pronotum 

 being also crumpled on one side.
