146 PHYMATID.E. 



Family PHYMATID^, 



Anterior legs short and stout, with long coxae, short thick 

 femora, and curvate pointed tibi?e ; frequently without tarsi. 



These are predatory insects. Uhler (Bull. IJ.S. Geol. & Geogr. 

 Surv. iii, p, 428, 1877) found some species in Colorado, generally 

 " prowling about upon the stems and flowers of the Euphorbias 

 and sunflowers, trying to catch the bees and other insects which 

 alighted there." 



Four genera and thirteen species are here enumerated, which in 

 this small family is probably a fairly representative number for 

 British India.
