54: INDEX TO MISSOURI ENTOMOLOGICAL REPORTS. 



crement. The structure of the covering is similar to that found in the egg of 

 texana Cr. (which feeds on Solanum eleagnifolium), where, however, the ribe are finer arid 

 transverse, and there is no excrementitious covering. The newly hatched larva of 

 guttata, like that of the other species is whitish, strongly recalling in general appear- 

 ance an ordinary mite, the head not being concealed as it subsequently is, the hairs at 

 the tip of the legs being frequently clavate or knobbed, and resembling those on the 

 young of many Coccids. The marginal spines and the anal fork are quite well devel- 

 oped but simpler than in the subsequent larval stages. This newly hatched larva is 

 quite nimble and crawls easily over glass. 



DELOYALA CLAVATA, Oliv. (Rep. II, p. 56) Now referred to the genus Coptocycla. 



BLISTER-BEETLES (Rep. 1, p. 96 ff. ) The larva' feed on locust eggs. For account 

 of their larval economy see my paper "On the larval Characters and Habits of the 

 Blister-beetles," etc.-, Trans. Ac. Sc. St. Louis III, p. 544 ft". : also Reports of the Com- 

 mission I, p. 292 ff. ; II, 262 ff. Remarks on synonymy are also there given, but the 

 following may be repeated. 



LYTTA CINEREA Fabr. (Rep. I, p. 97) This is now known as Ma-crobasis unicolor 

 (Kirby). 

 LYTTA MURIXA Lee. (Rep. I, p. 98) This is a color variety of Ulacrobtisis tinicolor. 



LYTTA MARGIXATA Fabr. (Rep. I, p. 98) This is believed by Horn to be a color-va- 

 riety of Eplcauta cincrca (Forst. ). 



LYTTA ATRATA Fabr. (Rep. I, p. 98) This is the Epkauta p<-i>xylc<tnica (De Geer) 

 of Crotch's List. 



AXTHOXOMUS PRUXICIDA, Walsh. (Rep. Ill, p. 39) Upon this species, which is a 

 synonym of sciitellaris Lee., Dr. Lecoute has since founded the genus Cocvotonts (Proc. 

 Am. Philos. Soc. vol. XV, 1876, p. 193). 



COXOTRACHELUS NENUPHAR, Hbst. (Rep. Ill, p. 127, note) Thephytophagic variety 

 of this species from Walnut and Butternut has since been characterized by Dr. Lecoute 

 as a distinct species, C. juylandis (Proc. Am. Philos. Soc. vol. XV, p. 226). 



CCELIODES IN^EQUALIS, Say (Rep. I, p. 128) Dr. Leconte has since founded upon this 

 species the genus Craponius (Proc. Am. Philos. Soc. vol. XV, 1876, p. 268). The egg of 

 this snout-beetle is quite large, bright yellow in color and deposited in a cavity half 

 as large as the beetle, though the puncture leading to it is small. The lateral angu- 

 larities or tubercles of the joints, as described by Walsh, are quite characteristic, and 

 the dorsal view in my figure, given to show them, conveys a somewhat false impres- 

 sion of the larva, which is more or less curved, and has the general characteristics of 

 Curculionid larvte. The figure is rather more attenuated than it should be. That 

 the beetle hibernates I have since proved beyond question. 



BARIDIUS TRIXOTATUS Say (Rep. I, p. 93) Dr. Lecoute (Proc. Am. Philos. Soc. XV, 

 1876, p. 287) has since established for this and two allied species the genus Trichobaris. 



SPHEXOPHORUS ZE.E Walsh (Rep. Ill, p. 59) This has been previously described 

 by Mr. Uhler as S. scalplilis (Proc. Ac. Phil. VII, 1855, p. 416). 



SPHEXOPHORUS PULCHELLUS Schoenherr (Rep. Ill, p. 60) As intimated in the foot- 

 note on the same page, this species is synonymous with Say's S. IS-itunctalus, for which 

 species and for Sphenophorua pustulosiis Gyllh. Dr. Lecoute has established the genus 

 Ehodolxenus (Proc. Am. Philos. Soc. vol. XV, 1876, p. 332). I have reared both, and also 

 intermediate forms, from Heliauthus in Texas, and Ambrosia in Missouri. 



SCOLYTUS CARY.E Riley (Rep. V, p. 107) Dr. Lecoute (Proc. Am. Phil. Soc. XV, 1876, 

 p. 371) has since decided that 4-spinosus Say is the $ of this species, and Say's name 



consequently obtains. 



LEPIDOPTERA. 



PAPILIO PHILEXOR Drury (Rep. II, p. 116) Referred byScudder to Hiibner's genus 

 Laertias. For further notes and description of the egg and young larva, see Canadian 

 Entomologist, January, 1881, p. 9, and American Naturalist, April, 1881, p. 327.
