ment deposited several eggs, in all respects identical with those found 

 deposited along the trunk of the apple tree in I\Iissouri. A careful 

 description of the eggs in both cases was made. They were deposited 

 on their sides under both conditions, but in confinement I did not 

 succeed in getting more than the few mentioned. 



Again at Urbana, Illinois, May 28, 29, 1908, several females of 

 this species were observed crawling slowly about amongst an isolated 

 but crowded colony of Lepidosaphes ulmi (Linnaeus), on the trunk 

 of a Carolina poplar (Populus deltoides Carolina L.), on the campus 

 of the University of Illinois. They were watched for four hours dur- 

 ing the afternoon of IMay 28, but none were observed to deposit eggs, 

 though their ovipositors were quite frequently exserted and inserted 

 into crevices and openings along the bark. The females were very 

 deliberate in their movements, crawling slowly about examining all 

 likely crevices, stopping frequently to feed upon the minute young 

 coccids, and occasionally to rest. They seemed to be particularly care- 

 ful in selecting a place for the nidus, if such was their purpose. It 

 was not until waiting several hours on the following morning that ac- 

 tual deposition was observed. The females were behaving as formerly, 

 but at 11 a. m.. May 29, one of them paused longer than usual while 

 examining a crevice with the ovipositor, and finally she was seen to 

 pass a single egg. This was deposited under a scale of bark, and the 

 egg was very well hidden. This egg was cut out of the crevice and 

 compared with the others found scattered in similar places through the 

 coccid colony, and all of the females were captured and confined in 

 the laboratory, where, however, they died from neglect, without ovipo- 

 sition. All the eggs found in this colony of Lepidosaphes hatched in 

 the laboratory, but I did not have time to secure data on the length of 

 the egg instar. After death the females were kindly determined for 

 me by Mv. Eugene A. Schwarz of the United States National IMuseum, 

 Washington. D. C, as the species under consideration. 



The description of the egg is appended : 



Normal: Color uniformly pale chrome orange; cylindrical, slightly thick- 

 ened towards the middle, the ends obtuse, subtruncate; surface shining, naked, 

 minutely punctate (half-inch Coddington lens), with moderately close, minute 

 papillae, within rather large, circular, deep punctures (two-thirds-inch objec- 

 tive, Bausch and Lomb), the latter inconspicuous, seen faintly at the change 

 of focus, as of an uneven surface; papillse resemble minute punctures. Micro- 

 pyle inconspicuous; chorion elastic. Length, 1.20 nun., average; greatest 

 width, 0.G5 mm., average. (From 14 specimens.) 



Deposited singly or in small groups of three or four, on their sides, in 

 crevices of the bark; attached, however, at the caudal end, along th<> latero- 

 caudal margin of one side, making that margin of the egg somewhat obliquely 

 truncate. The eggs are larger than with the more common species of the
