SCTMNUS. 229 



the eyes have a golden shining appearance, but in themselves are whitish or red ; and 

 the extreme tip of the front angle of the thorax is reddish in some examples. The 

 pubescence is dense and shining, like that of Azya, but in many examples this is 

 entirely absent. The base of the thorax is sinuous, and has a very fine marginal line. 

 The metasternum is strongly, almost coarsely punctured in the middle, more closely 

 and more finely so at the sides. The legs and abdomen are dark brownish-red; the 

 coxal fossettes reach the margin of the first segment. 



8. Scymims auritnlus. 



Scymnus auritulus, Muls. Spec. Col. Trim, secur. p. 985 1 ; Crotch, Hev. Coccin. p. 271 *. 



Hab. Mexico l 2 . Northern Sonora (Morrison), Guanajuato (Salle), Iguala in Guerrero, 

 Zacualtipan in Hidalgo, Jalapa, Teapa in Tabasco, Tapachula in Chiapas (Hoge), 

 Xucumanatlan and Chilpancingo in Guerrero, Cuernavaca in Morelos (H. H. Smith); 

 Guatemala, near the city, Aceituno (Champion). 



Specimens from the localities quoted have been compared by me with the type from 

 Reiche's collection, acquired by the late Mr. Crotch and now in the Museum at 

 Cambridge. 



The insect occurred abundantly in most of the localities mentioned. 



9. Scymnus horni. 



Suborbicularis, niger, capite, prothoracis lateribus et margine antico, pedibus, elytrorum. apicibus anguste, 

 abdominisque apice rufis, omnino breviter griseo pubescens. Long. 2 millim. 



Hab. Mexico, Northern Sonora (Morrison), Ventanas, Jalapa (Hoge) ; Guatemala, 

 near the city (0. S.), Quezaltenango, Duenas, San Geronimo (Champion) ; Panama, 

 Volcan de Chiriqui, Pena Blanca (Champion). 



This insect is clearly very closely allied to the recently described S. ardelio, Horn 

 (Trans. Am. Ent. Soc. xxii. p. 105). It was sent to us from Sonora labelled " Scymnus 

 marginicollis " : from that insect it differs (following Horn, loc. cit.) in having the legs 

 rrd ; but it does not agree with S. ardelio, according to the description. The apex of 

 the elytra, in the great majority of the examples, is very narrowly red, as is also the 

 pygidium, with the last ventral segment. Specimens which are presumably females 

 have all the red parts more obscurely coloured, and the tips of the elytra and abdomen 

 nearly black. There is apparently no tubercule on the first ventral segment. The 

 insect is a true Pullus. 



10. Scymnus jansoni. 



Suborbicularis, convexus, niger, parce pubescens, ore, an tennis, prothoracis lateribus, elytrorum vitta abbreviata, 



abdominis apice pedibusque saturate runs. Long. 1-25-1-5 millim. 

 Femina ? obscurior, elytrorum apicibus et pedibus tantum runs. 

 Var. elytris vitta deficiente.
