NOTES AND ADDITIONS : COLEOPTERA. 53 



MYSIA 15-PUXCTATA, Oliv. (Rep. IV, p. 18) This has been referred to the genus 

 Anatis, Mulsant. 



LACHXOSTERA QUERCIXA, Knoch. (Rep. 1, p. 156) This is synonymous with fusca 

 Frohlich, which has priority. The fungus affecting it (p. 153 and Rep. 6, p. 125) is Cor- 

 dyceps racenelii Berkeley. (See American Entomologist, III, p. 139.) 



CHAULIOGXATIIUS PEXXSYLVAXICUS, De Geer (Rep. I, p. 57 and subsequently) This 

 is now known as Ch. amsricanus Forst., the latter name having priority. For an ac- 

 count of the eggs and young larvte, see Second Report of the Commission, p. 261. 



SAPERDA BIVITTATA Say (Rep. I, p. 42) This is now admitted to be a synonym of can- 

 dida Fabr. For a correct description of the eggs and mode of oviposition, see an article 

 by me in New York Weekly Tribune, Feb. 20, 1878. 



BRUCHUS PISI Linn. (Rep. Ill, p. 44) This name of the 12th edition of Linnaeus's 

 "Systeina Natune" gives way in modern catalogues to pisorum L. of the 10th edition. 



FIDIA VITICIDA Walsh (Rep. I, p. 32) This species is not mentioned by Crotch in 

 his "Materials for the Study of the Phytophaga of theU. S." (Proc. Ac. Nat. Sc. Phil., 

 1873), but his Fidia murina (1. c. p. 33) is undoubtedly synonymous with Walsh's viticida, 

 the latter name having priority by several years. In Crotch's " Checklist" this species 

 is also omitted, but the Fidia vitis Walsh in the "Omissions" to that list (p. 127) is 

 probably meant for viticida. 



HALTICA CHALYBEA, Illiger (Rep. Ill, p. 79) This belongs to the genus Graptodera 

 Chevr. 



HALTICA CUCUMERIS Harris (Rep. I, p. 101) This is uowreferred to the genus Epitrix, 

 Foudras. 



PHYSONOTA QUIXQUEPUXCTATA Walsh & Riley (Rep. II, p. 59) This is synony- 

 mous with Ph. unipunctata (Say), there being no question as to the specific identity of 

 the two, both having been bred by Mr. F. H. Chitteudeu, of Ithaca, N. Y., from larvse 

 on a wild sun-flower (Helianthus). 



CASSIDA NIGRIPES Oliv. (Rep. II, p. G3) The eggs of this species are much like those 

 of aurichalcea (Rep. II, Fig. 31) in size, form and color, though the spiue-like appen- 

 dages break off more easily. They may, however, be distinguished by being larger 

 (1.6 mra long without projections), having, in fact, nearly double the bulk, and by the 

 flat posteriorly projecting piece which bears the spine-like appendages being gener- 

 ally greatly developed so as sometimes to extend beyond the apex fully one-third the 

 length of the whole egg. Sometimes this piece divides distinctly into three spines, 

 but in other cases it is quite blunt. 



CASSIDA BIVITTATA Say (Rep. II, p. 61) The eggs of this species are pale and 

 ovoid, just l mm long, but invariably covered with a yellowish secretion which dries 

 and spreads out each side, and this by a black excrementitious material which gives 

 the egg from above the appearance of an ovoid bit of excrement flattened on the ad- 

 hering side. The eggs are laid singly or in twos or threes. 



CASSIDA AURICHALCEA Fabr. (Rep. II, p. 62) This is now referred to the genus 

 Copiocycla Chevr. 



CASSIDA PALLIDA Herbst (Rep. II p. 62) This is now recognized as a synonym of 

 Coptocycla aurichalcea (Fabr.). 



COPTOCYCLA GUTTATA, Oliv. (Rep. II, p. 63) The eggs of this species, which I have 

 often since observed, are- deposited singly or in twos, threes or fours. They are rather 

 more than l mm long, of the same general form and character as those of Cassida bi- 

 vittata, but more narrow and elongate. The color is pale yellowish and translucent. 

 The egg is always covered with a viscid fluid which dries to form a transparent cov- 

 ering verging to fulvous or gamboge in color. This covering almost always spreads 

 out on each side of the egg in ray-like ridges, those on each side parallel and slightly 

 oblique, and whenever the egg is single these ridges are remarkably regular and have 

 a neat appearance. There is occasionally on the top of this a varying amount of ex-
