large Lycosa a Oordius 14 inches in length. Mr. Lugger related that from a 

 small specimen of Platynus cujn-eus he had drawn a Gordlus 11 inches in length 

 and left a portion still in the body. 



Mr. Smith described the brush of hair at the base of the abdomen in the 

 (^ of Lygranthoeda marginata. There is a groove between the dorsal and ventral 

 portion of the basal two segments and in this lies concealed a tuft of long hair. 

 It is fastened to a cup-shaped membraneous disc at the base of the abdomen, 

 and is twisted rope like for half its length. When first forced out of the groove 

 and expanded there was a very strong odor, similar to thatof the parallel organs 

 in P. iaabella and L. acrcea. Mr. Schwarz, who first called attention to these 

 organs a year ago at Ann Arbor, confirmed Mr. Smith's observation as to the 

 structure and the odor, and stated that he had succeeded in replacing a tuft into 

 its ^oove, though not so completely as it had been before being disturbed. 



Mr. Schwarz exhibited a male specimen of Merope tuber Newm., (family 

 Panorpidce), found by him under a stone near Washington on August 22nd, 

 and gave a history of this anomalous and rare insect. He also exhibited two 

 females of Chcvtoccelus setosus Lee, found on July 28th in the vicinity of Wash- 

 ington on dead oak twigs. The only hitherto known locality for this Malachiid 

 beetle was Columbus, Texas. Mr. Schwarz finally called attention to a beautiful 

 and undescribed variety of the common Conotrafhelus anaiilypticv.s in which the 

 reddish and orange colors of the pubescence are replaced by a beautiful .snow- 

 white. 



Meeting Oct. 2, 1886. — Mr. Howard read a paper on the larval habits of 

 Hydropsyche. He had foiind the larvse of a species of this genus very abundant 

 in Eock Creek near Washington where they were feeding upon the larvce of 

 Sbnulium. He described the webs and spoke at length on the habits. 



Mr. Lugger presented a list of a small collection of Coleoptera made at 

 Albaca, Bahama Islands, by members of the Zoological Station of the Johns 

 Hopkins University. More than three-fourth of the species are widely distrib- 

 uted, occurring from the Southern States of North America through the West 

 Indies to South America; the few species not occurring within the United States 

 are known from Cuba. Messrs. Smith and Schwarz added some remarks on the 

 character of the insect fauna of the Bahama Islands. 



Mr. Schwarz commenting on Mr. C. A. Dohrn's publication regarding the 

 occurrence of Lejyiura varncornls Dalm. in North America, stated that Dohrn's 

 Canadian specimen is no doubt a female of the common Leptura rxmadensvi var. 

 erythroptera. He further criticized Mr. Fleutiaux's attempt (ie Naturalisie, VIII, 

 No. 41, p. 327) to revive the question of the specific distinctness of Amblychila 

 Piccolomimi. 



Mr. Schwarz gave a history of the spread of Cnoceris asparagi within the 

 United States and reported its occurrence this season at Fortress Monroe, Va. 

 Fiom the circumstances under which the insect was found he concluded that it 

 did not gradually spread along the lower Potomac through the more northern 

 parts of Virginia but that it had flown directly across the Bay from the opposite 

 shore of Virginia. Mr. Lugger corroborated this opinion by relating his obser- 

 vations on the spread of the Crioceris in Maryland. During the past few 

 seasons the species had spread rapidly sonthward from Baltimore along the 

 shores of the Chesapeake Bay. 



Mr. Heidcmann exhibited some Hemiptera Heteroptera which he considers 

 rare or new to the fauna of the District of Columbia.
