LFAALOIIA Kirkaldy. 



Lelaluhn. Subgenus of Alalia Ivirkaldy, 1910, Fauna 

 llawaiiensis II, G, p. 579; type naniicola Kirk. 



1. L. naniiroJa (Kirk.). 



This species holds the same relationship to the typical 

 Uhuae as do the sub-species of Jehuae ; it will have to be in- 

 cluded, along Avitli oliiac, in a revision of the species when 

 more material can be bronght together. 



The pygophor is typical of the genus and the styles are all on 

 the same pattern, sickle-shape. The aedeagus is long, cylindrical, 

 slightly curved and recurved; the crook at apex small, placed about 

 45 degrees to the stem, slightly widened at the apex, with three small 

 spines; a small spine on right side near apex.

2. L. Jehuae (Kirk.). 



This is one of the most interesting species of the genus 

 and it appears to be the most polymorphic. At first I divided 

 the specimens according to coloration, and then noticed that 

 this grouping coincided with locality; an investigation of the 

 aedeagus show^ed distinct structural differences, and I then 

 decided to make them into species. There appears to be more 

 than one species among the Oahu specimens, but a lack of 

 time and material prevents me from making a thorough in- 

 vestigation, so for the present I leave the species divided into 

 four sub-species, with the remark that lehuae is polymorphic 

 and difiicult to separate from oJtiae except by the aedeagus.
