304 ENTOMOLOGICAL SOCIETY 



a tropical group with a Californian species, and the Oryidae, most 

 of which are tropical. 



FAMILY SCHENDYLID^E. 



The representatives of this family inhabit both continents, but 

 are' as yet unknown from the Malay region. 



The following synopsis affords diagnosis of the genera, to which 

 a statement of their known distribution is added. With the ex 

 ception of Pectiniunguis, the habits of which are here recorded for 

 the first time, the members of this family are to be found in the 

 humus of forests or cultivated grounds. 



Ventral pores wanting; anal legs provided with a normal claw; pleural 

 pores numerous, pigmented, scattered over the ventral surface of the last 

 pleurae; last sternum narrow: Genus Escaryus, type E. phyllophilus,* 

 New York. 



Ventral pores present; claw of anal legs rudimentary or wanting; 

 pleural pores few, unpigmented, opening into two large cavities which are 

 more or less concealed by the broad last sternum 



Anal legs 5-jointed : Genus Nannophilus, type N. eximius, Mediterranean 

 Region. 



Anal legs 6 jointed 



* A third species of this genus, Escaryus stbtrtcus, is represented by nu 

 merous specimens collected by Graeser at Vladivostock, Siberia, now pre 

 served in the Hamburg Museum. It is distinct from E. phyllophiius in 

 the much larger size, the more attenuate antennce, the wider cephalic 

 lamina, the less prominent nodule of the femur of the prehensors, the 

 very numerous and close-set pleural pores, and the minute claw of the 

 anal legs. The sterna have a very deep median foveola, and are beset 

 with short hairs, but are entirely without pores. The anal legs of males 

 are crassate, strongly curved, and densely hirsute. Larger individuals 

 measure nearly 65 mm. by 2.5 mm. ; pairs of legs 49 in males, 49 or 51 in 

 females. I have recently found, in a small collection secured by Professor 

 T. D. A. Cockerell at Dropping Spring, Organ Mountains, New Mexico, 

 still another member of the Schendylidae which suggests Escaryus in the 

 possession of a normal claw in the last joint of the anal leg. In other 

 characters it approaches Pectiniunguis, from which it differs greatly in 

 habit, being but about 15 millimetres in length, and having in the female 

 45 pairs of legs. From plate IV, figs. 4^ and 4^, it will be seen that the last 

 sternum is much broader than in Pectiniunguis, and that the proportions 

 of the anal legs of the two forms are very different, in addition to the dis 

 crepancy in the matter of the claw. The new genus and species may stand 

 as Holitys neomexicana.
