he two unique, stout, short, conical spines always found in the same relative position 

 near to and on opposite sides of the cleft and close to the base of the second joint of 

 the beak, in both sexes of each species under examination. The anterior legs present 

 a very interesting comb of about thirty spines, of nearly equal length and diameter, 

 lying in a straight row across the inner side of the apex of the tibiae, apparently useful 

 for toilet purposes. The pronotum and the regions of the coxae were mentioned 

 as showing an extraordinarily large size of pore-canals, passing through the thick 

 chitin, and probably affording means of exudation of secretions. In the description 

 of the wings the most striking feature was the curious interlocking apparatus. The 

 fore wing, or hemelytron, has on the under surface at the posterior edge, in the acute 

 angle of the anal cell or clavus, a prominence and this prominence has a deep pit. 

 The anterior edge of the pit has a single or multiple comb of depending spines, and 

 the posterior edge has a projection furnished with apparently fish-scale-like spines, all 

 provisionally named the ''wing lock." The hind wing has the costal or anterior 

 edge upturned for a short distance, directly opposed to the "wing lock,"' which up- 

 turned edge is also furnished with fish-scale-like spines, this upturned edge being 

 provisionally named the "wing hasp." When the wings are expanded the hasp 

 slides in the lock and is securely held. When the wings return to a position of rest 

 the hasp easily slides out of the lock. 



The address was illustrated by fifty-six lantern slides, of the speaker's own prepa- 

 ration, consisting of etchings on sheet gelatine, mounted between two cover glasses of 

 regulation sized lantern slides, the etchings being tracings of pen sketches through the 

 camera lucida from microscopical mounts of his own dissections. 



Mr. William T. Davis presented some remarks on " Some Interesting Insects 

 from New Jersey." 



Ptynx appeiidiatlatits Fab., an ant-lion, is mentioned from Brazil by Hagen. 

 Mrs. Slosson captured it in Florida. According to Mr. Nathan Banks it has been 

 found in North Carolina, and lately in New Jersey. The specimens exhibited both 

 came from New Jersey. One was captured by Mr. Frank E. Watson at South Lake- 

 wood on July 11, 1902, and the other was collected on July 30, 1905, at Lakehurst. 



Panchlora viridis Burm. is a delicately colored West Indian cockroach collected 

 by Mr. James Chapin in a house on Staten Island about the first of March. This 

 species has previously been reported from the vicinity of New York. 



CEcanthns pini Beut. The pine tree cricket was originally described from 

 Windham County, Conn., by Mr. Beutenmuller. The specimens exhibited came 

 from Lakehurst, N. J., collected in July and September. 



The moth Pygarctia abdominalis Grote is recorded from Florida, but the speci- 

 men shown was beaten from a cedar tree at Lakehurst, N. J., on the twenty-ninth of 

 May, 1905. The specimen was shown to Professor J. B. Smith and he wrote as fol- 

 lows : " This is an altogether new locality and a great extension of the range of this 

 insect. Its capture and the circumstances under which it was taken are well worth 

 recording." 



A specimen of Neci'ophorus puslidatus Hirsch was exhibited which was captured 

 on Staten Island beneath an eiectric light on July 19, 1905. The species is not men- 

 tioned in the New Jersey, Washington, or Cincinnati lists of Coleoptera. It is, how- 

 ever, recorded from the vicinity of Buffalo and Dr. Horn records its distribution from 

 the New England States to Texas.
