species superficially resembles heckii (with which I at first confused it), 

 but may be distinguished by the presence of a conspicuous tuberculiform 

 process near the anterior border of the margin of each of the three 

 abdominal segments immediately preceding the pygidium. It differs 

 also in having ihe median circumgenital pores disposed in a lax group, 

 instead of in a single chain, as in heckii. The dorsal pores on the 

 pygidium of tuherculatiis are greatly reduced in number ; the crowded

inner series, which is a conspicuous feature in hecJcii, is represented in 

 tuberculatus by three or four isolated pores only. 



Malenotti's type material was taken on Cymhidium tracJiyanum at 

 Florence. The species is doubtless of tropical origin. 



Lepidosaplies ulmi L. (Fig. 11.) 



The discovery of L. tuherculatiis in this country has attracted my 

 attention to a somewhat similar structure (which appears to have been 

 overlooked) in L. ulmi. The processes are smaller than those of tuher- 

 culatus and of a different form, being more or less acutely pointed ; but
