Tychius decoratus, Rosenh., Die Thier. Amlalus. 271 (1856). 



Habitat in intermediis Canarise Grandis, foliis Ononis natricis, L., 

 gaudens. 



After comparing carefully this superb Tychius with an Andalusian 

 type of the T. decoratus of Rosenhauer, communicated by Dr. Kraatz, 

 and also with another specimen (clearly referable to the same species) 

 which was taken by the Rev. Hamlet Clark at Granada, I cannot de- 

 tect any difference, either in sculpture or coloration, of sufficient im- 

 portance to warraiit its separation from that insect. The only points 

 in which the Canarian examples would seem to recede from the 

 Spanish ones are, first, that perhaps they are a trifle larger (though, 

 with only two individuals of the latter to judge from, I am scarcely 

 in a position to affirm this positively), and, secondly, that the sub- 

 sutui'al lines of their elytra are hroivner or more obscui'e, whilst the 

 sublateral ones are (like the suture itself) quite pale, and more or less 

 confluent— an arrangement of the scales which I do not see so deci- 

 dedly expressed in either of the types of the decoratus now before me. 

 Even if this, however, should be peculiar to the sx^ecimens from the 

 Canaries (of which I feel by no means certain), still I do not imagine 

 that such a character can be looked upon as indicating more than a 

 mere geographical variety : nevertheless, should future material from 

 the south of Spain prove the two to be really distinct species, I would 

 in that case propose for the Canarian one (fully enunciated above) 

 the trivial name of gloriosus. The only district in which I have 

 hitherto observed it is the great Barranco in the south-west of Grand 

 Canary in which the little town of Mogan is situated — where, on the 

 16th of April 1858, I captured it rather abundantly from off a bean- 

 tiful yellow Ononis (the 0. natria\ L.) which is common by the road- 

 sides, and on the dry mountain-slopes, of that particular region.
