generally indicated ; cervical grooves rather long, convergent and deep 

 throughout their length ; lateral grooves commencing behind the pseudo- 

 scutum and therefore short, well-marked to the spiracle and faintly con- 

 tinued to include two or three festoons ; festoons rather broad. Capitulum : 

 base broadest in front, the sides nearly straight and converging pos- 

 teriorly ; comua slight, but thei^e are also ventral cornna ; palps longer

than broad, sub-cylindrical, article 2 very salient beyond the base, but 

 the lateral contours of articles 2 and 3 form normally nearly a straight 

 line, only slightly recurved at the base of article 2^; no dorsal spurs, 

 but a slight point under article 3 ; hypostome 3 ; 3. Venter : anal 

 grooves slightly ogival ; spiracle large, with slight dorsal process. 

 Legs : two short spurs, internal and external, on coxa I ; a slight spur 

 on coxae II-IV ; very slight trochantal spurs ; tarsus IV long, stout, 

 tapering rapidly. 



' We have, however, received specimens (N. 1144) from Canada which are undoubtedly 

 H. leporis-palustrts, but in which article 2 of the palp is much more recurved at the base.
