AN ANNOTATED LIST OF ODONATA COLLECTED IN CENTRAL 



SPAIN BY DR. T. A. CHAPMAN AND MR. G. C. CHAMPION IN JULY 



AND AUGUST, 1901. 



BY ROBERT McLACHLAN, F.R.S., &c. 



This forms the second instalment of an enumeration of the species 

 of " Neuroptera " taken on the journey above noticed (cf. ante, pp. 

 129-130). The greater part of the materials were accumulated by Dr. 

 Chapman, Mr. Champion confining his attention more especially to 

 other groups. The number of specimens was very considerable, and 

 an examination reveals 23 species, or nearly a quarter of those found 

 in Europe. There is, I think, no reason to doubt that " experts," 

 whose attention was not claimed by other Orders in the first instance, 

 would have increased the List. The general aspect of the materials 

 is, of course, meridional ; nearly one half of the species occur in 

 Britain, but the Spanish forms of the same species are often very 

 considerably modified. T think the publication of the List cannot 

 but be useful ; in a country so little worked as is Spain, any items of 

 local information are valuable, and both Dr. Chapman and Mr. 

 Champion are to be congratulated on not forgetting that there are 

 other insects besides those to which their studies have been especially 

 directed. 



LIBELLULIN^E. 



Libelt.ttla depbess a, L. Tragneete, 1 ? , T. A. C. 



Sympetrfm flaveolttm, L., var. lfteoi/pm, Selys. Tragaeete, 1 c? , T. A. C, 

 Bronchales, many, T. A. C.,1^,1 ?,G. C. C. All the individuals belong to 

 the var. or " race " luteolum, which is probably the usual form in Spain. In it the 

 yellow of the base of the wings in the $ is connected with a yellow nodal space, 

 such as usually occurs in the 9 in the ordinary form, which elsewhere is probably 

 looked upon as only accidental in the $ . 



Dr. Chapman remarks especially concerning this insect as follows : — " In a 

 little upland valley between Bronchales and Noguera, at between 4000 and 4500 ft., 

 was a hollow that had all the appearance of being often a small pond. The whole 

 surface was covered with vegetation, not all of a semi-aquatic character. It was 

 obviously usually a pond, but dry for several months each year. We did not see 

 any permanent water within a mile or two, but there may have been some. <S. 

 Jlaveolum was in some numbers here, and a good many pairs were on the wing, the 

 females ovipositing industriously along the sloping edges. There were also several 

 other dragon-flies (such as Lestes dri/as) flying with them, but I am not sure 

 that any of these were ovipositing." 



Stmpetrfm meridionale, Selys. Tragacete, 1 £ , T. A. C. Albarracin, 1 ? , 

 G. C. C. True to the custom of the species this <? is most abundantly infested with 

 the usual red Acari on the wings, and these probably induced Dr. Chapman to 

 capture the insect owing to its singular appearance. The female has only very few, 

 but they are present.
