34 FOURTH ANNUAL REPORT OF 



gave in 1868. As usual, a number of cases of stinging were reported, and 

 my conclusion that such stinging is caused by the beak, is strengthened by 

 the experience of Dr. LeBaron. It was quite apparent that the eggs sel- 

 <lom, if ever, hatched from twigs which fell off the tree and became dried. 

 The foregoing record clearly proves the genuineness of five out of my 

 first six Broods, the third being the onl}^ one, so far, which must be re- 

 j ected. 



THE GRAPE-YINE COLASPIS, AGAIN— Colasp is fl a vida, 8a j. 



I have had an opportunity of ex- 

 .-•^N amining a number of additional speci- 

 mens of the larva of this insect, which 

 has continued its injuries to strawberry 

 T' c^ roots in some parts of St. Louis county 



and of South Illinois; and though I have nothing to add to its economy ac set 

 forth in my last Report, I find it necessary to revise the description of the 

 larva for the benefit of the entomological student. . As stated at the time, my 

 former description was drawn up from two rather poor alcoholic specimens, 

 and after more carefully examining a great number of good, living larvre, I find 

 that description not sufficiently accurate. Upon more careful study, this larva 

 plainly shows its Family characteristics, and the ventral appendages are rarely 

 as prominent as previously indicated (Eep. 3, Fig. 38), being in reality 

 but largely developed tubercles which the larva has the power of extending 

 or retracting. The folloAving description should therefore replace the 

 other : 



CoLASPis FLAViDA, Say— Laruo— Color yellowish. Body slightly arched. Anal joints smaller 

 than the others. First joint horny above and of the same color as head. Dorsum with about thi'ee 

 wrinkles to each joint and sparsely clothed with yellowish hairs, each springing from a minute 

 rufous polished point. Stigmata, 9 on each side, rufous, the first between joints 1 and 2, the others 

 placed on a lateral series of swellings, commencing with joint i. Joints 4—11 inclusive, each with S 

 substigmatal concolorous shiny plates (Fig. 16, a), the upper row lateral and divided from the 

 second by a longitudinal depression : the second row forming tubercles which are retracted or pro- 

 jected at will. Head (Fig. 16, b, under side; c, upper side), honey-yellow, rounded, slightly flat- 

 tened in front; epistoma and labrum of same color: mandibles darker, triangular, with the inner 

 edge slightly excavated near the tip; antenna; apparently two-jointed, short and with the terminal 

 joint often bifid; maxilke well developed, the inner lobe furnished with strong hairs; maxillary 

 palpi prominent, 4-jointed; labium sub-obsolete; labial palpi forming simply two small piliferous 

 tubercles. Legs scaly, pale, setous, and terminating in a brown claw. Anal joint not horny below. 

 Length, 0.2!>— 0.30 inch. 



Described from numerous specimens .
