Genus TARACHODES Burmeister. 



TARACHODES WERNERl. new name. 



1907. Tarachodes perloides Werner, Sitzungsb. k. Akad. Wiss. Wien, Matli.- 

 nat. Kl., vol. 116, Abth. 1, pp. 192, 208, pi. 3, figs. 1-2. [Southwest Africa.] 

 (Not of Burmeister, 1838.) 



Loanda, Angola. One male. 



It is evident on comparing the original description of Tarachodes 

 perloides Burmeister ^ mth Werner's key for the species of the genus 

 and notes on perloides as recognized by him, that the latter is in 

 error in the association of his specimens. Burmeister states dis- 

 tinctly, "ventre rufescente, segmentis 2-punctatis/' while Werner 

 in his key gives as one of the diagnostic characters of perloides 

 "abdomen subtus immaculatum." It is quite probable that true 

 perloides is the same as either sancta Saussure or maura Stal, both 

 of which have the abdominal segments bimaculate ventrad. With 

 the material available at the present time we can not say which of 

 these names should be replaced by the older perloides. Under any 

 circumstance perloides of Werner is not perloides of Burmeister, and 

 a new name is required for the former. I take pleasure in dedicating 

 the species to the author of the very valuable paper in which its 

 characters were described and the species figured. 



TARACHODES DIVES (S.iussure). 



1869. Ch[iropuii\ dives Saussure, Mitth, Schw. Ent. Ges., vol. 3, p. 61. [Ben- 

 guella.] 



Loanda, Angola. (H. Chatelain.) One female. 



Mossamedes district, Angola. One female nymph. [Acad. Nat. Sci. 

 Phila.]. 



From this material it is apparent that Werner^ was mistaken in 

 referring the female specimen of this species from Benguella 

 described by Saussure^ to T. perloides Burmeister as recognized by 

 him.* The specimens before me fully agree with Saussure's origmal 

 description and figure and differ from Werner's figure in the more 

 elongate pronotum, which is slightly constricted caudad. The ce- 

 phalic margin of the pronotum is also more arcuate, the lateral angles 

 less decided, and the caudal margin more decidedly truncate 

 nicsad. The width of the head in proportion to that of the prono- 

 tum is considerably greater in the female of dives than in Werner's 

 figure of the same sex of perloides {=werneri).
