During the sprino- of 190G .several weeks were spent in eastern 

 Guatemala by Messrs. PI A. Schwarz and H. S. Barber, who are both 

 skillful collectors, having- special aptitude for the discovery of minute 

 forms of insect life. Being coleopterists, their particular attention 

 while collecting was naturally directed toward beetles, but that other 

 groups were not neglected is well proven by the following list of For- 

 ficulidte collected by them. There are 88 specimens of these earwigs, 

 representing 18 species, distributed in 18 genera, of which 6 species 

 and 1 genus are undescribed. All of this material is in the United 

 States National Museum. 



The locality most frequently mentioned— "Cacao"— is situated in 

 the Province of Alta Vera Paz, between Panzos and Senahii, at an 

 altitude of about 900 feet, near the foot of the waterfalls, above which 

 the coti'ee plantation of Trece Aguas is situated. 



Notes by Mr. Barber are appended to the discussions of some of the 

 species. These notes are inclosed in quotation marks. 



DIPLATYS JANSONI Kirby. 



Two females. Cacao, Trece Aguas, Alta Vera Paz, March 26, 31. 



"One specimen beaten from dead banana leaves, the other from dead leaves from 

 a recently felled tree. This species so closely resembles the very common Stapylinid 

 beetle, Paederm hrtus, in form, coloration, and movements that it was by accident 

 we discovered that it was a Forticulid, and it is probable that many more specimens 

 were seen without being recognized." 



DIPLATYS SEVERA Bormans. 



Two males, females, 2 larva. Cacao, Trece Aguas, Alta Vera Paz, 

 April 13-21. 



These larvae exhibit the slender, many -segmented anal cerci, as 

 described by Westwood some years ago under the synonymous genus
