96 HIPPODAMIA. 



II. ylacialis; the six spots all generally marked, the scutellar 

 spot linear or absent ; the second spot largely developed. 



Hippodamia convergens.

 „ „ M uls. Spec. p. 22. 9. 



United States, California, Mexico. Punctuation obsolete, 

 Elytra opaque; the six spots all present but small : elytra some- 

 times spotless. 



Hippodamia ambigua.* 



Hippodamia ambigua, Leconte Proc. Phil. p. 131. 3 (18-52). 



" Black, tborax punctulate, lateral and anterior margin, and 

 two dorsal marks more or less white, elytra red, strongly punctu- 

 late, base whitish, suture with the base black." L. '2 — 27. 



California and Oregon. Very close to H. convergens, but dis- 

 tinct by the strongly punctulate elytra, which are usually spotless. 

 The thorax varies in the development of white, the anterior margin 

 and the discal marks sometimes disappear. 



Hippodamia punctulata.* 



Hippodamia pimctulata, Leconte Proc. Phil. p. 131. 4 (18-52). 



" Black, thorax strongly punctulate, with two dorsal marks, 

 anterior angles, and the apical margin (produced in the middle) 

 white ; elytra punctulate, red, pale at the base, suture black at the 

 base." L. - 27. S. Francisco. Very near II. ambigita, thorax 

 more strongly punctured, the white of the sides extends only half 

 way to the base, and the dorsal spots sometimes wanting, the pos- 

 terior angles sometimes white. 



Hippodamia sinuata.

Advnia interrogans, Mills. Op. vn. 139 (185G) T. 



California. My specimen, which agrees precisely with Mul- 

 sant's description, is much more opaque than any other species, 

 especially on the elytra. Mulaant's interrogans is supposed to come 

 from China, which appears to me unlikely. 



Hippodamia spuria.*
