522 Mr. G. J. Arrow on some 



and mucli move scantily s|5otted whli wliite, the spots being 

 always extremely small and not infrequently absent alto- 

 gether. The antennse, head, and pygidium are red, but not 

 the last ventral segment, and the pyoidium is not spotted 

 •with white, whereas in our specimen of L. ruhriceps there are 

 four marginal spots. The body is a little longer and less 

 sharply narrowed behind, and the strise on the posterior part 

 of the elytra are less crowded. 



In both these species the inner spur of the hind tibia is as 

 long as the first two joints of the tarsus. 



Mr. Peringuey has .transferred L. ruhriceps to the genus 

 Mausoleopsis, on account of tlie asymmetrical front claws of 

 the male, thus disregarding not only the general form, but 

 more important characters common to both sexes, e. g. the 

 prominent terminal spiracles of Mausoleopsis. It appears to 

 me highly inadvisable to base any genus upon a feature 

 found only in one sex.

This is a species allied to L. spoliata, Har., which is 

 referred by Dx. Kolbe to his subgenus Amourijia, but it 

 differs from all the known species of that section in that the 

 elytra only are opaque. It is of short form, witli the pro- 

 notum subcircular, very strongly punctured, the hind angles 

 obliterated, and the sides decorated with a border of greyish 

 hairs. There are six white spots forming two diverging 

 straight lines upon the pronotum, three or four at the poste- 

 rior part of the outer margin of each elytron^ and usually a 

 few very minute ones upon the disk. The pygidium and 

 lower surface are fairly well clothed with grey hair, and 

 there are sometimes four basal patches of scales upon the 

 former. 



The sexes seem almost identical.
