Family POLYDESMIDAE, Leach. 



Genus PARADES M US Saussure. 

 Paradesmus evides sp. nov. Coloration as in P. erythropyyus. Form more 

 slender. Vertex smooth, median sulcus continuous, not much excavated between die 

 antennae. First segment more rounded. Inner angle of the lateral carinae not 

 serrated. Genitalia entirely different, short, robust, pilose, scarcely bent, grooved 

 ibove at the end, and divided into two blunt lobes. 

 Length of body 26 mm. ; width 4 mm. 

 Habitat. Winona, Minnesota. 



I have examined one whole specimen and a number of broken 

 ones, collected by Prof. J. M. Holzinger. This species can be easily 

 seperated from erythropygus by the markings of the vertex, the smooth 

 lateral carinae and especially by the male genitalia. 



Family GEOPHILIDAE, Leach. 



Genus GEOPHILUS Leach. 



Geophilus glaber sp. nov. Olivaceous, head, antennae and mouth parts 



brown, an indistinct black, median dorsal line. Robust, attenuated posteriorly, not 



pilose, punctate; sternum wider than long; coxae longer than wide (7:5), armed: 



claw moderately curved, teeth weak. 



Cephalic plate large, narrowed behind, longer than wide (10: 8); frontal plate 

 present; basal plate more than twice as wide as long (10: 4), partly covered by the 

 cephalic plate. First joints of antennae long. Anterior spiracle very large, oval; 

 posterior small, nearly circular. Dorsal plates bisulcate; anterior predorsal plate 

 small, posterior large; ventral plates with a median sulcus. Posterior coxae not 

 much swollen, pores above and below, large and small. Last ventral plate large, 

 sides rounded, not converging much. Anal pore large. Last pair of feet of female 

 slender. Pairs of feet of the female 53-55. 



Length of body 50-53 mm., width 2.5 mm. 

 Habitat. Utah, California. 

 I have examined three females collected by Mr. James K. Burke. 



Observations on some North American Capsidae. 



By P. R. Uhler. 



Through the kindness of Mr. Andrew Bolter, I have recently re- 

 ceived many important forms of this interesting group, some of which 

 were the results of his careful collecting in distant parts of the United 

 States, including localities as widely separated as Florida and California. 

 Dr. Hagen has also sent me for study the extensive collections of these 

 insects belonging to the Agassiz Museum at Cambridge, Mass. Also, 

 other friends too numerous to mention, have placed their specimens at 

 my disposal, so that 1 have at length been able to study long se.Ls of 

 nearly all the described Capsidae of North America. 



While studying the material alluded to, I have met with certain 

 synonyms; and some new species, which I desire to record at this time.
