MISCELLANEOUS NOTES. 



BY NATHAN BANKS. 



1. Andrena carlini Ckll. Sucking Sap. 



Mr. Banks exhibited specimens of this species which he found 

 sucking the sap from maple stumps at Falls Church, Va., on the 

 14th of March and later dates. So intent or so intoxicated 

 were they that they did not fly on repeated sweeping of the net 

 in catching the flies, and a number of specimens were taken 

 up with the fingers. All were males. 



2. Syrphus fisheri Walton, in Virginia. 







The author exhibited a specimen of this fly, described from 

 Pennsylvania, which he had taken at Glencarlyn, Va., 14 July, 

 and so determined by Walton. 



3. Apterous Females of a Caddice-fly. 



Specimens of Philopotamus distinctus Hag. were exhibited, 

 mostly taken by Mr. Shannon near Plummer's Island, Md. 

 The male was normally winged, but the females had the 

 merest rudiments of wings. Since winged females of this species 

 are well known, Mr. Banks considered that this apterism was due 

 to some local cause, possibly operative only the present season. 



4. Color in Hibernating Chrysopa interrupta Sch. 



The author showed specimens of this rather uncommon chryso- 

 pil taken during the past winter by Mr. McAtee at Mt. Vernon, 

 Va. The specimens were found in dry leaves clinging to a fallen 

 tree. Many of the specimens were unmarked, but a number had 

 a more or less extensive pattern of red markings on the head and 

 thorax, possibly due to frost; one had a reddish head. No simi- 

 lar variation has been recorded in other chrysopids, and hiberna- 

 tion was previously unknown in this species. 



5. The Genus Ceratoacarus Ewing (Acarina). 



In the Ent. Tijdskrift for 1914, p. 186-187 Dr. Tragardh calls 

 attention to the fact that this genus is a synonym of Labidostomma, 

 a fact that I recognized at once and wrote Dr. Ewing. Dr. 

 Tragardh takes this as an occasion to criticise American Acarol- 

 ogists for not knowing the (literature of this group. Am I to 

 judge all European Acarologists by the mistakes of a few? 



I am familiar with all the literature cited by Tragardh, and it 

 is really he who does not know the literature. For he spells 

 the genus Labidostoma several times, when it originally was 

 spelled Labidostomma, and moreover he states that this record
