CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 665 



Amnestus signoreti Distant 



Amnestus signoreti Distant, 1893, p. 452. 



Original description: 



Black; lateral and frontal margins of head, lateral margins of pronotum and 

 cerium, legs, and antennae pale castaneous. Head with the usual frontal and 

 lateral spines; head, pronotum, scutellum, and corium thickly and coarsely punc- 

 tate; pronotum with a somewhat obscure transverse incision; membrane pale 

 hyaline, ochraceous at base. 



Long. 2>^ millim. 



Hab. Guatemala, Quich6 Mts. 7000 to 9000 feet (Champion). 



The thickly and coarsely punctured upper surface and the pale castaneous 

 lateral margins are the salient features of this species, of which we possess only a 

 single example. 



Remarks. — The Zoological Record (vol. 90, p. 477) review of 

 Carvalho's (Bol. Miis. Nac. Rio de Janeiro, No. 118, 1952) treatment 

 of the Miridae in the Biologia Centrali-Americana reported that 

 Amnestus signoreti Distant had been transferred to the mirid genus 

 Mimoncopeltus. This is in error. In the above paper Carvalho did 

 not indicate Distant's generic placement of the species; and the 

 reviewer, who apparently overlooked the mirid species Lygdus signoreti 

 described in a footnote on page 419, used the combination Amnestus 

 signoreti instead. 



Amnestus dallasi Distant 



Amnestus dallasi Distant, 1893, p. 453. 



Original description: 



Black; antennae, eyes, lateral margins of the pronotum, a broad sublateral 

 fascia to the corium, and the legs pale castaneous; membrane pale ochraceous and 

 subhyaline, the base and apex very pale castaneous. Head coarsely punctate, 

 with the frontal and marginal spines well developed; pronotum with an obscure 

 transverse incision, the anterior lobe with a few scattered discal punctures, and

Amnestus bergrothi Distant 



Amnestus bergrothi Distant, 1893, p. 453.
