elytra, or wing-covers, are marked with darker irregular spots similar 

 to those on many kinds of birds' eggs. The ventral surface is a 

 bright mahogany brown, and moderately hairy. 



The larva, shown in Plate II, figure 1, at a^ in natural position, is of 

 the usual curved Scaraba?id form, dirty yellow or j^ellowish white in 

 color, measuring when mature upward of 5 inches in length when 

 extended. Enlarged illustrations of the mandibles are shown at 1> and 

 G of the same figure. 



The pupa is light brown in color and covered with a very fine 

 velvetj^ pruinosity. The male is illustrated in Plate II, figure 2, a 

 showing a lateral view and Ij the dorsal, natural size. 



The peculiar odor of the beetle is shared by larvte and pupte and 

 lasts long after death, preserved specimens seeming never to lose this 

 strange scent, which also remains for years in the insect boxes in 



which the beetles have once 

 been kept. 



In the reports of Dr. Lintuer 

 rather full bibliographical ref- 

 erences can be found. 



DISTKIBUTION. 



The exact distribution of this 

 species has never been defined,

 calities from which specimens 

 have been sent by correspond- 

 ents of this Department together 

 with some recorded localities 

 should be of interest, this bee- 

 tle being so well known to 

 collectors of insects:
