also in Mr. Pratt's collection several others differinf^' so widely 

 in coloration as to have the appearance of being distinct 

 species ; but upon careful examination I am unable to find 

 any other characters to separate them, and must therefore 

 treat them as varieties ; and although I am generally opposed 

 to the giving of distinctive names to mere varietieSj I do so 

 in this instance, as they are well-marked forms of which no 

 intermediate variations connecting them occur in the collection.

Bahooni, British New Guinea {A. E. Pratt). 



Allied to L. rufa, Kz. ; very similar in coloration, but the 

 thorax and elytra of a darker or more castaneous red ; it is 

 also larger and of a broader form ; the ciypeus is more 

 dilated in front, making the apical lobes less acute -, the thorax 

 is proportionately broader at the base, rather sparsely punc- 

 tured, and not strigose at the sides ; the elytra are more 

 strongly sinuate behind the shoulders and not so closely 

 aciculate : the pygidium in the male is similar in form, but
