THE ENTOMOLOGIST. 179 



to the fact, separates the rufipes, Gyl., generically under the 

 name of" Dolotarsiis," and proposes tlie name " Stephensii" 

 for our species, which, he states, differs from P. Vaudoueri 

 in having the thorax more rugose, the fovea? at the base 

 scarcely visible, and the elytra with elevated lines ; the ter- 

 minal joint of the maxillary palpi is also narrower. The 

 French species appears to be extremely rare. The synonomy 

 will therefore stand thus : — Phloeotrya Stephensii, Duv.,

115. Latridius testaceiis, Steph. — This species is identical 

 with L. cordaticollis, Atibe (Ann. Soc. Ent. Fr. 1852). The 

 Stephensian name, being accompanied with a figure and good 

 description, must of course stand. — Id. 



116. Ceuihorhynchus iiiornatus, Waterh. — This species 

 is identical with C. Alliarite, Bris. (Ann. S. Fr,, 1860, 537), 

 which name, being oldest, must be retained. This was 

 pointed out to me by M. de Baineville himself, who had seen 

 specimens from England. — Id. 



117. Monotonia ^-foveolata, Aube, — This species was ori- 

 ginally introduced into our lists on specimens of a nearly- 

 allied species, common near London, and which M. Aube 

 informs me is the M. rufa, Redt. Mr. Waterhouse had pro- 

 visionally designated it " subquadrifoveolata." I find on 

 inspection of Mr. Janson's collection that he has found the 

 true 4-foveolata at Hainault Forest, and had so designated it 

 in his boxes. It bears considerable resemblance to the M. 

 rufa, but has the four fovese much more distinct, the thorax 

 nearly quadrate instead of elongate, and its margins are very 

 plainly thickened ; the elytra also are less pubescent. — Id. 



118. Occasional Abundance or Rarity of certain Species. 

 — It is, I think, an interesting subject for inquiry why many 

 Lepidoplera are so abundant at times, and then disappear 

 for years. For instance, in the year 1862, Vanessa Cardui 

 was very plentiful in this district, but I have not taken a 

 single specimen since. The larva of Yponomeuta padella 

 was excessively abundant in 1863, stripping the foliage from 

 the whole of the blackthorn-bushes in one part of this Island, 

 but last year it did not once come under my notice. — Henry 

 Moncreaff ; Southsea.
