ns Jajian is of its eastern boundary. "^i'lic best time for 

 searching for tlie species is June and early in July; they are 

 diurnal, and occur in the his/her rej^ions of larn;e forests. I 

 found tlie species in JajKin cliietly on deciduous trees, elm, 

 oak, and celtis, and thoy seemed to feed on various sub- 

 cortical ajid wood-boring Colo()|)tera. It is likely that there 

 are unrecognized species in collections, as one from Borneo 

 remained in the Pascoe collection for many years until 

 detected by Mr. Arrow. 



Species of two other peculiar genera have been recently 

 discovered in the Nilgiri Hills by Mr. II. L. Andrewes which 

 have a like distribution from Japan in the east to India in 

 the west, viz. Trppeticus and Fachylomalus^ and in both 

 instances the species are very similar to each other. Jlister 

 jmvctulatus, Wiedem., one of the most curious species in the 

 family, occurs in Bengal, and I have found it in China and 

 Jaj)an ; the species sjiould now be placed in Zabromorphus, 

 as it has longitudinal antennal fossai. 



It is by the peculiar genera and species of a family that the 

 connecting-links in a fauna are principally shown, not by the 

 ordinary genera, such as Ilister and 8aprinus, which are 

 world-spread.

 Lew., is a variety in which the first dorsal stria is interrupted 

 in the middle; in more than fifty examples I have since seen 

 the first dorsal stria is comj)lete, as shown in Marseul's figure 

 (pi. xi. fig. 10, Monograph, 18G0). 



Trypanaus thoracicus, F., and T. torpedo, Lew. 

 The females of these species are very similar to each other,
