234 COCCLNELLID^E. 



S. grumus, and in those examples I suppose to be females the head and thorax are 

 quite obscure. Of these three small species the present is the largest, it being also 

 more oblong than the others. 

 Eight examples are before me. 



20. Scymnus aspersus. (Tab. XII. fig. 26.) 



Breviter oblongus, luteus, pubescens, prothorace antice angustato, basi infuscato, vel medio indeterminate 

 fusco ; elytris basi sutura, margine laterali ad medium ampliato, ante apicem desinente, punctoque 

 discoidali nigricantibus. Long. 1 millim. 



Var. Prothorace saturatiore, elytris nigro-variegatis. 



Hal. Mexico, Toxpam {Salle), Teapa in Tabasco (H. H. Smith) ; Guatemala, near 

 the city, Duenas (Champion). 



This little insect seems to be very variable. The two examples from Teapa appear 

 to have, at first sight, four spots on the elytra, but the basal ones are only prolongations 

 of the basal black on the disk. The black colour extends down the margin as far as 

 the posterior discoidal spot, and is there widened as if it would join it: in two 

 examples the spot returns in the form of a vitta, leaving only a vague yellow ring on 

 the elytra, the scutellar region being more widely suffused. The breast is pitchy. 

 This is one of the smallest of the Scymni, but is scarcely so small as S. grumus and its 

 allies. 



Seven specimens. One from Teapa is figured. 



21. Scymnus diversus. 



Breviter oblongus, luteus, pubescens ; prothorace maculis duabus anterioribus, duabus posterioribus vel tribus 

 basalibus haud bene discretis fuscis ; elytris plaga laterali pone medium provecta nigra, interdum 

 macula parva suturali postmediana. Long. 1 millim. 



Hah. Guatemala, San Geronimo and Cahabon in Vera Paz (Champion). 



This insect in form and general appearance is very like S. aspersus ; it is, 

 however, differently marked. The thorax in the example from San Geronimo has 

 four distinct nearly black spots, and the elytra have a wide lateral blotch, extending 

 halfway across each elytron. There are indications of black markings here and there 

 on the elytra, one of which becomes a distinct spot on the suture at about one-third 

 from the apex. 



In the example from Cahabon the thoracic spots are less distinct, but more wedge- 

 shaped, and there is in addition a central basal spot. The body beneath and legs are 

 yellow. 



I have not been able to identify any of the following species, and we have not 

 received any Seymni from Yucatan.
