412 MEMOIRS ON THE COLEOPTERA 



next three combined, the latter subequal among themselves and 

 about as long as wide. Hind wings are almost certainly wanting. 



The male example in my collection was received from Mrs. 

 Fuchs, and is in all probability the same as that described and fig- 

 ured by Mr. Schaeffer (Bull. Am. Mus,, N. Y., XIV, p. 210). Its 

 dimensions are 5.0 by 1.8 mm. It was labeled "Pasadena, Los 

 Angeles Co" as received, and has never, so far as known, been com- 

 pared directly with the original type of barbarce, taken at Sta. Bar- 

 bara, by Mr. Fuchs. It agrees very well with the original descrip- 

 tion of barbarce, however, except in one particular, for it is said in 

 the description that there are the usual dorsal punctures, which 

 would mean two discal and widely separated and one subapical ; in 

 the specimen here referred to this is not true, there being about six 

 punctures on each elytron, irregularly disposed in two close-set 

 series. 



There are so many homologous characters pervading Pogonus, 

 Patrobtis, Platidius and Trechus, and some closely related genera, 

 that the course favored by LeConte and Horn, placing them all in 

 a single subfamily Pogoninae, would seem to me more appropriate 

 than the division into two subfamilies, Pogoninae and Trechinae, 

 now advocated in the European lists. In this subfamily Pogoninae 

 there are several tribal groups. Pogonus is very poorly represented 

 in North America by three genera and three species Pogonus tex- 

 anus Chd., Pogomstes planatus Horn (depressus \\ Lee.) and Diplo- 

 chcetus parallelus Lee. (lecontei Horn). The last two are considered 

 subgenera of Pogonus by some systematists, but this is not neces- 

 sary or advisable, as the three groups differ among themselves very 

 much in habitus, as well as structural characters.
