I have but little hesitation in referring the present insect to the 

 L. curtum (a species which was established by myself, in 1854, on 

 a single individual taken near Funchal in 1848); for although the 

 Canarian exponents are somewhat larger than the type from which 

 I drew out my diagnosis, they possess so completely, in all other 

 respects, the characters to which I drew attention, that I cannot 

 but conclude that my original example must have been an acci- 

 dentally small one, — a supposition which the capture, during my 

 last visit to Madeira, of a series of specimens "f corresponding 

 precisely with the Canarian ones would certainly tend to corrobo- 

 rate. It is by no means peculiar to the Euphorbias; nevertheless 

 since it is very frequently to be met with in the dry branches of 

 those plants, it could scarcely be omitted from the present paper. 

 I have taken it in Lanzarote, Fuerteventura, Grand Canary, 

 TenerifFe, Palma and Hierro. 



29. Leiparthrum inarmaium,* Woll. 



L. breviter subovato-cylindricum, fusco-nigrum, pilis rigidis 

 cinereis (praesertim postice) vestitum ; prothorace antice sub- 

 attenuato inarmato (i. e. tuberculis carente); elytris profunde 

 striato-punctatis, interstitiis leviter elevatis, apicem versus 

 plerumque paulo dilutioribus necnon ad apicem subtruncatis ; 

 antennis (capitulo vix obscuriore excepto) tarsisque testaceis.

t These specimens were found boring into an old paling above Porto da Cruz, 

 on the eastern side of the island, during January, 1859. Athough somewhat 

 broader than the L. bituberculalum, like their Canarian representatives they are 

 of about the same length as that insect, — ranging from two-thirds to seven eighths 

 of a line.
