insect in certain years and partially controls it, so that it is 

 only periodically destructive. 



Doctor Howard stated that it was remarkable that no hymen- 

 opterous parasite had yet been found to infest Aleyrodes citri, 

 for parasites are common on the other species of Aleyrodes. 

 He said that California was a heaven for such parasites, and 

 he predicted that, if the white fly obtained a foothold there, 

 some species would become parasitic upon it.

NOTES ON HEIDEMANNIA CIXIIFORMIS UHLER AND 

 OTHER SPECIES OF ISOMETOPIN.ffi. 



[HEMIPTERA— HETEROPTERA.] 



By Otto Heidemann. 



Years ago Prof. P. R. Uhler published a description of 

 H eidemannia cixiiformis,^ a new genus and species of the 

 family Capsidse. The description was taken from three speci- 

 mens collected by Mr. E. A. Schwarz and myself near Wash- 

 ington, D. C, 1890; at Oakland, Md., and near Fort Pendle- 

 ton, Md. This remarkable insect is very peculiar in form, and 

 its whole habitus is somewhat distinct from that of a capsid. 

 Professor Uhler remarks in his description that other speci- 

 mens are needed for dissection to work out the elements and 

 affinities of this antique pattern of the Capsidse. No other 

 specimens had been found, in spite of close searching during 

 the summer seasons, until 1902, when Mr. N. Banks met 

 with a single specimen that was perhaps resting on the bark of 

 a maple tree at Falls Church, Va. But this summer, July 4, 

 the much-wanted insect was again captured by Messrs. Schwarz 

 and Barber at the famous collecting ground of Plummers 

 Island, Maryland. A few days later I was so fortunate as to 

 find the nymph form on the same tree from which the adults 

 were taken. Recently I received the same species as an un- 

 named Capsus from Mrs. A. T. Slosson. She caught a single 

 specimen near Delaware Water Gap, Pa. 



The insect lives apparently in damp and shady places on the 

 twigs of dead trees. It has the jumping habit, and Mr. 

 Schwarz observed that it leaps for quite a remarkable distance.
