Ascalaphus ictericus, Charp. — Tangier, 14th June ; 2 ? . 

 [Ohrysopa vulgaris, Schneid. — Tangier, Blaclcmore.~\ 



OBONATA. 



Lepthemis trinacria, Selys. — Esmir, 25th September; 1 very adult ? , 

 almost entirely " saupoudree " as in the adult $ . 



Orthetrum ccerulescens, E. — Esmir, 16th July ; 1 adult ? . 



Orthetrum Ramburii, Selys. — Esmir, 25th July ; 1 adult $ . 



Diplacina flavistyla, Eamb. — Esmir, 16th July ; 1 $ . A new district 

 for this wide-spread species. I submitted the example to my friend 

 Baron De Selys-Longchamps. 



N.B.— In the " Eevue des Odonates," p. 312 (1850), De Selys 

 gave parvula and Lefebvrei, Ramty., as synonyms. To this he would 

 now add tetra, Eamb., originally from Mauritius, and since found in 

 Madagascar, and, I think, Zanzibar ; it sometimes, not always, has a 

 faint dusky band under the pterostigma, which induced Eambur to 

 place it in a separate section : he also adds concinna, Eamb., probably 

 founded on an immature <j> . I am quite disposed to agree with him, 

 and think the different forms are partly due to differences in locality, 

 and especially to differences in degree of maturity. In this case 

 ■flavistyla is widely distributed : — Mauritius, Madagascar, Delagoa Bay, 

 Zanzibar, Gaboon, Senegal, Marocco, Algeria, Egypt, Arabia, &c, and 

 perhaps Palestine. Judging from my own materials, I should doubt 

 the advisability of retaining the synonyms as varietal names. It is 

 perhaps not a true Diplacina, taking D. nana, Brauer, as the type. 



Onychogornphus uncatus, Charp. — Benzus Bay; 1 $, 



Corduleqaster annulatus, Latr. (var. immaculifrons, Selys). — Benzus 

 Bay, 24th June ;" 1 $ . 



Anax formosus, V. d. Lind. — Esmir, 16th July ; 1 <£, 2 ? . 



Hemianasc ephippiger, Burm. — Esmir, 16th July; 2 <$ . 



Calopteryx hcemorrhoidalis, V. d. Lind. — Benzus Bay, 25th August ; 



Lestes virens, Charp. — Esmir, 16th July ; 1 <$ , which has the back of 



the head discoloured (?), and hence the appearance is deceptive. 

 Lestes barbara, E. — Esmir, 16th July ; 1 ^ 



[Sympycna fusca, V. d. L. — Tangier, Blaclcmore ; one example is 

 labelled " December ;" the insect hibernates.] 



Ischium Oraellsii, Eamb. — Esmir, 16th July; 2 £ , 1 ? [also from 

 Tangier, Blaclcmore, several examples.]
