HEMIPTERA, IQI 



species. Of these, only three, representing three genera, have been 

 catalogued from the United States. Our forms can be separated 

 by the following table: 



A. Fore-legs stout, fitted for grasping! 



Anterior tarsi with a single claw. MONONYX. 



BB. Anterior tarsi with two claws. CALCULUS. 



AA. Fore-legs slender, fitted for running. PELOGO 



Our three species are Mononyx stygicus, Gdlgulus oculatus, and 

 is americanus. Fig. 161 represents the Galgulus ; the Mon- 



r closely resembles this in form ; while the Pclogonus is a smaller 

 insect, with a more oblong body, and of a velvety black color. All 

 of the species are predaceous. 



Family XVII. SALDID^:* 



With the S(i!(fi(fic we reach the beginning of the extensive M 

 of families of Heteroptera, in which the antennas are prominent and 

 are not concealed beneath the head. In this family the in-

 The head stands out free from the thorax on a cylindrical b 

 The antenn;e are four-jointed ; there are two ocelli ; the 

 rostrum is three-jointed and very long, reaching to or 

 beyond the middle coxae. The membrane of the wing- 

 furnished with looped veins, forming four or

 is little or no distinction between the corium and mem- 

 brane. Two forms sometimes occur in the same sp t 

 one with a distinct membrane, and another \\ith the membi 

 thickened and almost as coriaceous as the corium proper.
