TORTKICES TAKEN IN SOUTH ESSEX. 167 



collis Stal {=Aegaleus heclmana, Kirk.), Lihyaspis wahlhei'gii 

 (Stal), &c. Of the last named, there is at present only a single 

 mangled male, without scutellum ; but I think the identification 

 is correct. 



I have great pleasure in naming this species after its dis- 

 coverer, Mr. Henry Brown. The difference of head-structure in 

 the sexes will separate the genus from Lihyaspis, the only genus 

 with which it can be confused. In G. browni, the length of the 

 antennal segments, and of the head, &c., vary slightly ; while 

 the amount of dark blotching is much less in one male than in 

 the other. 



9. Amorgius cordofanus (Mayr, 1852, larva), {^-niloticimi, 

 Stal, 1854).— Kangra Valley, 4500 ft. (G. C. Dudgeon). Oblig- 

 ingly determined as niloticum by Mr. A. L. Montandon. 



10. My friend Mr. E. P. van Duzee considers {in litt.) that I 

 have fallen into error in placing ^Li&Mrwia as a synonym of 



Emholophjjora (Entom. 1901, p. 340). On looking again into the 

 matter, I quite agree with him that Emholophpora, 1853, is not 

 synonymous with Lihurnia as understood by later authors. The 

 five species included in Lihurnia by him in 1866 (Hem. Afric. iv. 

 pp. 179-81), however, belong to at least three genera, and no type 

 is stated. 



A LIST OF TORTRICES TAKEN IN SOUTH ESSEX 



BETWEEN 1885 AND 1901. 



By a. Thurnall. 



(Continued from p. 134.) 



Roxana arcuana, L. — This beautiful insect usually occurs pretty 

 freely wherever oak and bracken are growing together. I have still 

 to learn how, where, and wheu the larva feeds, and upon which of 

 these two very distantly related plants ! 



Euchromia purpurana, Haw. — Local, but occurs in several places, 

 usually preferring rough uncultivated ground; not often in good con- 

 dition wheu eaptured. Larva on roots of dandelion and other allied 

 composites in May. Warley, Thames Haven (sea wall), Upminster, 

 &c. My darkest and largest specimens came from Wicken. 



Orthotamia striana, Schiff. — Generally common in similar localities 

 to the last ; I have met with it in all the localities where I have col- 

 lected. Larva feeds in the " crown " of the dandelion and other 

 composites. The female is not so readily obtained, and is very 

 much smaller. 



0. (J) hrandcricma, L. — I have taken this in three localities : Wan- 

 stead (but not for some years), Ongar Park Woods, and in the 

 neighbourhood of Colchester amongst aspen. 



0. ericetcma. — This species surely ought to be found, but I am 

 obliged to confess that I have never seen a specimen alive either in 

 Essex or any other county !
