Para, Brazil, with the statement that its bite is said by the natives 

 to be fatal. He reviewed the superstitions in English-speaking 

 countries of the dragon-fly. Mr. Schwarz suggested that per 

 haps the correspondent had sent the wrong insect not the one to 

 which the superstition is attached, and further stated that dragon- 

 flies are not feared in Germany. 



Dr. Dyar exhibited a new species of the genus Lophyrus, 

 reared from the larva collected by Mr. Pratt on Arborvitae at 

 Woodstock, Va.' He presented for publication the following de 

 scription of this species : 



A NEW SAW-FLY. 



By HARRISON G. DYAR. 



Lophyrus pratti, n. sp. 



9 - Antennae 2o-jointed. Black, shining, posterior angles of prothorax 

 and pleura shaded with luteous; legs luteous, whitish on the joints and 

 reddish on tarsi, coxae at base and center of femora black ; tibiae and tarsal 

 joints outwardly a little blackish. Lanceolate cell with straight cross-line ; 

 veins black. Length 5.5 mm. 



Larva. Thorax thickened, thoracic feet moderate, the head small in 

 proportion, 1.6 mm. wide; abdomen tapering posteriorly, the anal seg 

 ment small. Segments regularly 6-annulate, the spiracle on the second 

 annulet, the segmental incisures practically indistinguishable from those 

 of the annulets. Very minute points on the first, second, fourth, and 

 sixth annulets and on the subventral folds, rather numerous. Whitish 

 green, a shaded, but defined dorsal band, obscurely geminate ; a similar 

 band on the side just above the spiracles, broad, continuous, and single, 

 both bands grayish black, unbroken. Feet pale, the abdominal ones on 

 joints 6 to 13. Head round, shaded with leaden over the vertex, pale be 

 low; eye black. Differs from abietis Harr. in the pale head and thoracic 

 feet, and apparently also in having onlv one stripe on the sides. (I have 

 not seen abietis larva in nature.) Differs from the pine-feeding Lophyri 

 in being without spots. 



One 9 bred by F. C. Pratt from larvae on Arborvitre* at 

 Woodstock, Va., in June. 



NOTE. Since the above description was read, it has trans 

 pired that all the larvse preserved by Mi\ Pratt are probably in 

 the ultimate stage, not in the last feeding stage as 1 supposed, 

 hence the above comparisons with allied species are not valuable. 

 I suspect that L. pratti is the same as the common Lophyrus 



* The plant was determined by Mr. Pratt in the field. It is probably the 

 Thuja occidentalis.
