Fam. EHIPID0CEEID51*. 



This is a family of small extent, represented in Central America by three genera — 

 Callirrhipis, Ptorthocera, and Sandalus. In the first two the legs are not very stout, 

 the tarsi are simple, the mandibles are rather short, and the gular appendages (" pieces 

 jugulaires ") are strongly developed, at least in our species ; in Sandalus the legs are 

 usually robust, with the tibiae dilated at their outer apical angle and the tarsal joints 

 dilated and bilamellate, the mandibles are long and stout, and the gala is without visible 

 appendages. The females, so far as known, differ greatly from the males in all the 

 species. Dr. Horn refers the genus Vesperoctenus, Bates f, containing a single species, 

 V.flohri, from Mexico and Lower California, to this family; Bates included it in the 

 Longicornia, a position also assigned to it by Mr. Gahan.

Of the fifty-eight known species of this genus, fifteen only are American, these being 

 distributed between Mexico and Monte Video and Chili. From within our limits eleven 

 are now recorded, of which eight are described as new. The females appear to be very 

 rare in collections J ; they diifer from the males in having the body usually almost or 

 quite glabrous and the antennas pectinate (instead of flabellate), as well as in their 

 larger size and less parallel shape. We have received specimens of both sexes of seven 

 of the Central- American species, the females of three of them (C. laportei, C. vestita, 

 and C. unicostata) having been found in some numbers. In all of them the long, 

 movable, horny, gular appendages ( u pieces jugulaires") are very conspicuous. 

 C. laportei has the eyes small and prominent ; it probably belongs to Celadonia, Cast. 

 (=Simianus, Blanch.), but is connected with the typical Callirrhipis by intermediate 

 forms.

J Mr. C. 0. "Waterhouse, in 1877, in his remarks on this genus, stated that he had not seen the female of 

 any American species, and there are none in the British Museum to this day.
