128 [Nuvember, 



kindly sent me a typical specimen of virescens, and I have also re- 

 ceived from Mr. Saunders specimens belonging to the species described 

 by bim as Ortliotylus concolor. Botb these species are identical. 

 But in examining the specimens, I have found also that L. virescens, 

 Doug, and Scott, and Orth. concolor, Saund., are synonymous with the 

 true Capsus cliloropterus, Kirschb. To this species are also to be 

 referred many specimens, sent by Mr. Douglas, under the name of 

 Litos. concolor. It is clear that all these specimens belong to 0. chlor- 

 ,opterus, Kirschb. (nee Doug. & Scott), and not to concolor, Kirschb., 

 for Prof. Kirschbaum says in the description of the former (Eh. 

 Wiesb., pp. 156 & 157) : " viridis, hemelytris saturatim, parum niti- 

 dus," " capite (cj) supra ohsolete lonffitudinaliter sulcaio,'' " rosteWo 

 perbrevi,^^ " pronoti lateribus pcene marginatis,^'' "membrana infuscata, 

 nervo griseo, circa cellulam minorem dilute luteo," " tibiarum spiuis 

 nigris,^'' and further: " Schnabelscheide sehr kurz, nicht bis zu d6n 

 Mittelhiiften reichend " (the rostrum does not reach to the apex of 

 va.Q»o^ievnvim),^^ gesdttigf grimen, wie iihertunchten SalhdecJcenr All 

 these characters accord with Litos. virescens, Doug. & Scott, and 

 Orth. concolor, Saund. (nee Kirschb.), and there is no doubt that 

 Ortliotylus cliloropterxis, Kirschb., is the right name for these species. 

 I have also received the same species from Dr. Puton, under the name 

 of cliloropterxis. 



LiTOSOMA CONCOLOR (Cat., 31, 7). According to specimens, sent 

 from Messrs. Douglas and Scott to M. Sahlberg and myself, JMessrs. 

 Douglas and Scott have described under this name two very allied, but 

 yet distinct, species : Ortliotylus chloropterus ( (^ ) and the true O. 

 concolor, Kirschb. The latter differs from the former by the following 

 characters, taken from the diagnosis and description by Prof. Kirsch- 

 baum (Rh. Wiesb., pp. 155 and 156) : " dilute viridis," " antennis? 

 ])ectore, tibiarum spinis, tarsisque sordide dilute lutescentibus,^' " mem- 

 brana dilute fusco-hyalina, nervo sordide lutescente, inter cellulas 

 viridi," " Fiihler, Glicd 1 ungefahr halb so lang als der Kopf," " die 

 Halbdecken * * etwas durch scheinend." It has, further, the 

 rostrum longer, reaching to the base of the second pair of coxae. 



LiTOSOMA PEASiNA (Cat., 32, 13) . Mr. Saunders writes to me : 

 " Hyps, prasinus, Doug, and Scott, = Ortliotylus Jlavosparsus, C. Sahib. 

 The specimens are old and broken, but the green cell of the membrane 

 is still clearly visible."
