﻿ON SOME LYRAMORPIIA-SPECIES. 



49 



easily be separated by the following characters, noted by 

 me in Leyden : 



L. rosea: Limbo costali corii olivaceo (»3eneo" teste West- 

 wood). Corio apice extus concolore, haud pallido-maculato. 

 Pronoto rugoso-punctato. Segmento genitali maris profunde 

 inciso, incisura fundo piano, lateribus curvatis (fig. 1). 



1. L. rosea Westw. 2. L. pallida Westw. 



L. pallida : Limbo costali corii roseo. Corio apice extus 

 macula distinctissima pallida ornato (semper?). Segmento 

 genitali maris minus profunde inciso, incisura angulari (fig. 2). 



These characters show sufficiently that the species must 

 be treated as distinct. Horvath, when he wrote his mono- 

 graph, had certainly before him L. pallida only, as is 

 shown by the figure of the segment he reproduces. 

 His L. rosea must thus be regarded as a synonym of 

 L. pallida of Westwood. The true L. rosea Westw. was 

 unknown to him. 



The figures I add here, were kindly drawn for me after 

 the Leyden-specimens by Dr. van der Weele. They clearly 

 represent the striking difference of the apical segment in 

 the (j^ of both species. 



2. Lyramorplia Vollenhovii Stal and YoUenhoveu. 



In his »Essai d'une Faune entomologique de TArchipel 

 Indo-neerlandais", third monograph, the Hague 1868, van 

 Yollenhoven describes (pp. 35 and 36) and figures (PI. IV, 

 fig. 3) a Lyramorplia, which he identifies with Stal's 

 L. Vollenhovii [Tijdschr. v. Entom. (2) II, p. 124 (1867)].
