PHYTHOLAEMA HEKRMANNI Germain 



FiGUBE 1, dr-h 



Phytoloema herrmanni Germain, Aual. Univ. Chile, vol. 108, p. 994, 1901. — 

 Rivera, Rev. Chilena Hist. Nat, vol. 8, p. 241, 1904 (biology). 



Picpotestaceous, elytra somewhat lighter, thorax very slightly 

 lighter at center of disk but not distinctly bicolored, clypeus and 

 legs testaceous. Head with front piceous, coarsely densely punc- 

 tured; clypeus with dense, long, erect hair, apex moderately re- 

 flexed. Thorax somewhat coarselj^ densely punctured over entire 

 disk and with long erect brownish hair. Scutellum sparcely punc- 

 tured. Elytra coarsely punctured, slightly rugose, with four dis- 

 tinct oblique carinae on each elytron, with several scattered long 

 erect hairs. Metasternuni usually densely hairy. Middle and hind 

 tarsi equal to or longer than their respective tibiae. Antennae with 

 the fifth segment seven-eighths the length of the sixth in the male, 

 and one-third or almost one-half the length of the sixth in the 

 female. Length, 11 to 12 mm ; width, 6.5 to 7.5 mm. 



Material examined: 6 males, 2 females, from "Angol" (Sept. and 

 Oct.) and from "Galvarino" (Sept.). Chile. 



The fifth segment of the antennae in both sexes is consistently a 

 little longer than the same segment in the like sex of mutabilis. 

 The present species differs from the two others in the genus espe- 

 cially in the longer middle and hind tarsi, as well as in the much 

 more densely punctured and more hairy thorax and in the strongly 

 evident elytral striae. 



PHYTHOLAEMA HERRMANNI PALLIDA, new subspecies 



Entirely testaceous. Body robust and somewhat shorter than in 

 the typical species. Tarsal claws with basal tooth varying from 

 rather fine and smaller than in the typical form to being almost 

 absent. Other characters as in typical herrmanni. Length, 9 to 10 

 mm ; width, 5.5 to 6 mm. 



Holotype and paratype^ both males (U.S.N.M. no. 52093) are 

 from "Southern Chile" and were collected by M. J. Rivera. 



A very conspicuous form presenting a different appearance super- 

 ficially from herrmanni but in reality only a subspecies of that; all 

 the major characters except the color, size, and tarsal claw formation 

 are as in the typical form. The male genitalia are also identical with 

 those of herrmanni.
