to the flowers of Clethra, the Amelanchier bushes produce 

 Saperda Candida and /S. tridentata. and Sassafras in this 

 neighborhood seems to harbor an nnnsnal number of Oberea 

 ocellata and 0. ruficoUis. Chinquapin bushes are common 

 and to their flowers come a horde of longicorns of the 

 genera, Leptura, Strangalia, and others; Balaninus of a 

 number of species; and once in great abundance Amphicoma 

 ursina. The Beltsville vicinage has many large ant colonies 

 and ant guests are more than ordinarily common. Species 

 of Microdon have been mentioned, and among others several 

 species of Cremastochilus also have been collected, including 

 the rather scarce C. Iniochii. 



In connection with Hemiptera, Beltsville is of interest as 

 the type locality of the strikingly colored Reduviid Psel- 

 liopus barberi, and of certain varieties of species of the Mirid 

 genus Paracalocoris. Tree hoppers inhabiting chestnut and 

 hickory are especially common. 



Odenton, Md., is another sandy locality of considerable 

 interest to collectors. Near the station, and somewhat cut 

 up by railway embankments is one of ihe best developed Mag- 

 nolia bogs of the region. In late summer Polygala lutea and 

 the white-fringed orchid here makes a gorgeous show. Scrub 

 or bear oak {Quercus ilici folia) is common at Odenton, and 

 indications are that the locality will repay search for other 

 Pine Barren plants. The country near Odenton has proved 

 to be a particularly good place for collecting Hemiptera, 

 especially Miridae. It has yielded some very desirable 

 beetles also, among which are Cremastochilus leucostictus 

 and the austral ^leloid, Teti-aoiii/.r fiuadriiiiaciilata. 



Laurel, Md., on the Patuxent River, is one of the locali- 

 ties from which both Piedmont and Coastal Plain conditions 

 are easily accessible. The gorge of the river above the town 

 is very interesting and has been found a good collecting 

 locality. Three young men will long remember a Decoration 

 Day spent there, when Yellow-bellied Flycatchers were com- 

 mon, and two Mourning Warblers and a Philadelphia Vireo 

 were collected. The Patuxent River is bordered by extensive 

 swamps below Laurel, and hidden in these are bogs which 

 still yield pitcher plants {Sarracenia purpurea), white-
