XIV MONTHLY PROCEEDINGS 



June 2d. Junonia Laoinia : the entire insect above darker than 

 usual. Beneath, the median band on primaries is quite white, with 

 the usual ocellus very distinct, the apex deep ferruginous; the sec- 

 ondaries uniformly deep ferruginous with the ordinary spots faintly 

 visible. 



Mr. Blake also made some remarks on the form of the scales of 

 Morpho Cypris and M. Sidkowskyi, and exhibited drawings of the 

 same; he stated that the stems of the scales, as seen under the 

 microscope, showed the attachment to the mem- 

 brane of the wing to be similar to a ball and 

 \ socket joint. Prof Westwood also mentions a 



1 V jj 2 ' 11 similar arrangement in the scales of the " rugose 

 portion" of the wing of Ilipparchia Seme/e. 

 \ Mr. Blake had examined the scales of the last 

 named species, but failed to find the stems as 

 -7^ 2^ distinctly balled at the insertion as those of the 



species of Morpho above mentioned. Fig. 1, rep- 

 resents a magnified scale of Morpho Sullcowskiji ; 2, of M. Ci/pria ; 

 3, of Ilipparchia Semde^ from the rugose portion, the extremities of 

 the scales being tufted with hairs; 4, normal form of the scale of 

 If. Serrifde. The small figures on the right show the socket attached 

 to the membrane of the wing, in which the stems are inserted. 



Dr. Horn made the following communication on the Elateridge. 

 The species of Adelocera in our fauna divide into three series 

 as follows : 



Prothoracic tarsal grooves deep, distinctly limited, uniting posteriorly with 

 the antennal groove I. 



Prothoracic grooves feebly impressed, neither distinctly limited nor joining 

 the antennal grooves 2. 



Prothoracic grooves entirely absent 3. 



The first scries contains species separable as follows : 



i'liiictures of elytra in regular rows; median impression of tliorax feeble. 



12. iiiipre!iiMic*olliH. 

 Punctures dense, not in series; thoracic impression deep. 



Elytra gradually narrowed from base to tip; surface marmorate with brown 



and luteous 7. niariiiorata. 



Elytra parallel, narrowed at apical third. 



.Surface black with white scales very sparsely placed 0. MparHa. 



Surface densely clothed with fulvous scales 5. pyr^iolcpiM. 



The species of the .second series are known as follows: 



Elytra with jjunctures in rows; prothoracic channel almost entirely obliter- 

 ated: surface sparsely scaly 13. niodeNta.
