Phthiracarus contractilis ( I'crty) 

 (Figure -.'H) 

 This species was deserilH'd from decayed wood in Germany. My .speciiiieiis 

 were found under drift-wood on salt marsh, Fawson I'ark, Conn., in Auf(U!it. 

 Length of my specimens is 8.S8 niicrni. to 1 mm. (measured front tip of nhdomen 

 to dorsal suture). The side view is identical with /••. rflalluus. Differs from 

 that species as shown in figures by rounded tip of nhdonien and different forms 

 of unguis as shown in the eorr«'s])onding small figures. The ventral views, with 

 eephalothora.x closed down are shown, whili- the position of the eephnlolliora.x 

 when open is indicated hy the dotted line.

 (Figure 2J'2) 

 Oiffirs from the species as descrilud hy Banks in tiie following particulars: 

 The bristle at the tip of the penultimate joint is not as long as the larsu.s. 

 The two spines on the hind tarsus are proximal to the middle of that joint. Length 

 of my specimen, a male, .7 mm. Tarsus I in my specimen is much longer and 

 thinner than that illu.strated by Banks in Bulletin LS. Tarsus I also has a cur\ed 

 s|)ine at the tip which is almost as large a.s the claw. 



Sent from Banning. Cal., where a colony was injuring the bark of an apple 

 tree.
