108 CANARIAN COLEOPTERA. 



with its uniformly brassy-black surface, its very obsoletcly striated 

 elytra, and its rather abbreviated, piceo- testaceous (sometimes nearly 

 piceous) limbs, will suffice to separate it from the preceding species. 

 It is apparently rare, Grand Canary and Hierro being the only islands 

 in which I have hitherto observed it.

Habitat in Canaria, TenerifFa et Gomera, ad flores, rarus. 



This common European insect (which occurs sparingly at Madeira) 

 is decidedly rare in these islands. I have taken it at Maspalomas in 

 the extreme south of Grand Canary, as also at Souzal and the Agua 

 Garcia in Teneriffe ; in the last of which, as well as in Gomera, it 

 was found likewise by Dr. Crotch. 



Fam. 13. NITIDULID^. 



Genus 73. HETEROBRACHIUM (nov. gen.). 



Corpus, antennce et instrumenta ciharia fere ut in Bracliyptero, sed 

 protliorace magis quadrate (in utroque sexu diverse), ahdomine nisi 

 fallor simplici (segmento terminali ut mihi videtur hand aucto, ut 

 in Cerco), p>alporum ma.villarium articulo ultimo longiore subaci- 

 culari ad apicem truncate, paraglossis vix distinctis. Pedes graci- 

 liores quam in Bracliyptero, necnon in sexu masculo multo longi- 

 ores ; antici longiores quam posteriores, in maribus longissimi : 

 femorihus (proesertim masculis) ad apicem internum angulato-den- 

 tatis : tihiis gracilioribus quam in Braeliyptero necnon ad apicem 

 externum minus angulatis, anticis ibidem etiam oblique truncatis 

 et spina interna magna robusta ciu'vata auctis [calcaribus in posteri- 

 oribus minoribus ajqualibus], anticis in maribus valde curvatis, in 

 foeminis subrectis, intermediis in maribus subcurvatis, in foeminis 

 reetis, posticis in utroque sexu rectis : tarsis et unguicidis ut in 

 Bracliyptero, sed articulo basilari paulo angustiore.

As will be seen from the above structural comparative diagnosis, 

 the insect for which I have proposed the present genus has much in 

 common with Bracliypterus. In its external facies indeed, antennae, 

 and oral organs it is so nearly identical with the members of that 

 group that it might thus far at least have been almost associated 

 with them ; though at the same time I must confess that I cannot
