ME. a. LEWIS ON JAPANESE LANGURIID^. 357 



I obtained about fifty specimens : the plain of Eujisan and 

 Junsai are the chief localities. 



Langhtria nigeitabsis, C. "Waterh., is very closely allied to L. 

 pectoralis. The type is a male, with sexual characters as above, 

 and it is still unique in my collection. 



Langueia Lewisii, Crotch, has the fore femora of the male 

 very clearly denticulate (fig. 8) ; the middle and hind tibise are 

 less so. The fore tibia, viewed from the front with an ordinary 

 glass, appears regularly denticulated ; but a detached thigh, 

 under a high power, shows that the denticulations consist of two 

 rows, and that the placement is by no means uniform. The tibiae 

 of the male have the apical process almost obsolete, and in this 

 particular agree with the two following species. 



It is a common species at Kobe and Nikko and in a few places 

 in Higo. 



Lakguria geniculata, Harold. 



I transcribe for reference the author's diagnosis: — "8upra 

 senea, subtus rufa, metasterno abdominisque triangulis apicalibus 

 SBnescentibus, pedibus rufis, geniculis tarsisque fuscis, antennis 

 sensim dilatatis fusco-rufis, articulis 4, ultimis fuscis. Long. 

 7 mill." 



If I have determined this insect correctly, it comes very near 

 to L. Lewisii ; but the antennae have the 7th and 8th joints less 

 transverse. Of forty specimens only three have the legs coloured 

 as Harold describes them, and his description does not give the 

 sexual characters, which are the same as in i. Leioisii. 



Kobe, Oyama, Kashiwagi are localities for it, and I saw it in 

 great abundance in the forest behind the large temple at Nara 

 in June. 



LaNGUEIA NAEA, U. Sp. 



Near Nara I obtained two males and two females of a Lan- 

 guria, which measure only 4| mill. They are very parallel, with 

 humeral angles scarcely prominent ; and as there are no inter- 

 mediate forms in my long series of L. geniculata, I give them a 

 provisional name as above. I have several single examples which 

 apparently belong to as many species, but I leave them over until 

 more material is available.
