Type species Calospasta opaca G. H. Horn. 



This genus cannot be confused with any other. From 

 Gynaptery.v Fairm. et Germ, (which is a Henous with winged 

 $ $ ) it can easily be told by its unequal claws and short elytra 

 of the 5 . 



Other apterous forms occur in various divisions of the fam- 

 ily, such as Hornia and Leonidia (Sitarini) and Tricrania 

 (Horiini), but should not have too much stress laid on them 

 from the standpoint of general classification, although the 

 presence or absence of wings among the Lyttidae is usually a 

 good generic character. 



Taking up now in order some of the genera helpful in de- 

 ciding on a scheme of classification I may say that Sybaris 

 should probably be regarded as related to the Mylabris group, 

 although its claws have the superior division pectinate. This 

 relation can be traced through Alosimus, Lydus and Oenas to 

 Mylabris. The mouth parts of Oenas and Alosimus are very 

 like Mylabris (the mandibles being dissimilar, i. e., the right 

 and left mandible different), Lydus being a little farther re-- 

 moved in this respect. Cordylospasta is to be considered as 

 also rather near Mylabris, although its generalized features are 

 not so like as its appearance suggests, and the antennal and 

 other common characters may possibly be due simply to paral- 

 lel development. Its claws, etc., place Cordylospasta near Cys- 

 teodcmus, Megetra and the Calospasta group of genera. The 

 larval no less than the adult characters of the Cerocoma and 

 Mylabris groups place them close tokether. Eletica, while hav- 

 ing some points in common with the Mylabrines, is by virtue 

 of its having mouth parts like Pyrota (i. e., with all the parts 

 differentiated and isolable) is a link between the group last 

 mentioned and the Lyttines. 



The gradations in the Lytta division (through the series of 

 genera allied to Calospasta) toward the Meloines are gradual 

 and evident. The genera Henous, Gynaptery.v, Gynaeconichc, 

 etc., have already been mentioned in this connection. 



Between the Meloc forms and the Sitaris tribe the break is 

 on the whole greatest and it is here that I propose to divide
