28 MISCELLANEOUS BESULTS OF WORK OF BUREAU IX. 



C. texanus Long. 



The larva? of this species are gregarious in small numbers beneath the bark of old 

 dead trees in moist places, or on the under side of very damp rotting wood during 

 December and January. Rare.a 



Austin, Tex. 



C. wheeleri Long. Adults of this species have not been reared on 

 account of a proetotrypid parasite (Adeliopria longii Ashm.). 



The Ceratopogon puparia were found December 15, 1900, beneath a stone, in what 

 seemed to be an abandoned ant's nest. The parasites issued, one from the thoracic 

 dorsum of each of the Ceratopogon puparia December 31 and lived eight or ten days.& 



Austin, Tex. 



The late Dr. O. Lugger c calls attention to the "cussedness" of 

 an unidentified species and gives a figure which may possibly be C. 

 stellifer. Ceratopogon has also been recorded as breeding under 

 leaves and in flowing sap from trees; thus the group is seen to have 

 diversified habits. 



In Europe, Professor Mik d described' as Ceratopogon Jiippocastani 

 a hairy-winged species having a footless larva, found in the very 

 moist or wet ulcerous parts of stems of horse-chestnut (^Esculus 

 hippocastanum ) . 



OTHER BLOOD-SUCKING CHIRONOMID^l. 



A related form which may be mistaken for Ceratopogon is (Ecacta 

 fur ens Poey, taken in June at Cardenas, Cuba, by Mr. E. A. Schwarz, 

 and at Montserrat, West Indies, April 8, by Mr. H. G. Hubbard. It 

 was also taken at Perihueta and Laguna Carmen, Mexico, by Dr. 

 Alfredo Duges. 



Another related form, Tersesthes torrens Towns., described by Prof. 

 C. H. T. Townsend e with notes on habits, has been collected at the 

 following localities: Filmore Canyon, and Las Vegas Hot Springs, 

 N. Mex. (Townsend); Fort Grant, Ariz., July 19 (H. G. Hubbard); 

 Ash Fork, Ariz., June 18 (H. S. Barber); Lake Worth, Fla. (Mrs. 

 A. T. Slosson); Salt Lake, Utah (H. S. Barber), and Baracoa, Cuba, 

 August (A. Busck). 



Mr. Barber has collected from thirty to forty species of Ceratopogon 

 and states that Tersesthes is much worse as a pest than any Cera- 

 topogon he has ever encountered.
