form and ornamentation of the bcdy, more broadly reflexed side 

 margins, more depressed surface and emarginate mesosternum are all 

 departures from Coccinclla, to which these species have been at- 

 tached, and the two genera are not even closely allied. The genus 

 Neohannonia probably includes also the Mexican ampla Muls. , which 

 I have not been able to examine. Our two species are the following : — 



Broadly rounded, feebly convex, relatively strongly and unequally punctate ; head 

 black, yellovif along the eyes ; pronotum pale, with a large oblique fascia of black 

 at each side extending from near the sides to the scutellum, gradually narrowing 

 inwardly and departing slightly from the basal margin externally, also with two 

 approximate median spots before the middle, which are sometimes united with the 

 basal fasciae at about their medial points ; scutellum black ; elytra pale yellow or 

 reddish, each with two large subquadrate subbasal black spots and one still larger 

 just before the middle, subtriangular and near the margin, also a large subquadrate 

 spot near the margin at apical fourth, extending to inner third, where it is united 

 with a common sutural vitta extending from near the apex to just behind the middle, 

 also with a rounded spot just before the middle and near the suture, prolonged in- 

 ternally obliquely forward meeting — but not quite amalgamating with — its dupli- 

 cate of the other elytron at the suture some distance behind the scutellum, form- 

 ing two oblique inverted commas ; under surface and legs blackish. Length 

 6.0mm.; width 4. 7-5.0 mm. Indiana; \_notiitata vnr. A Muls.] . . venusta Aid Ji. 



Similar in fonii to venusta but smaller and less strongly and less unequally punctured, 

 black above, the elytra with violaceous reflection, the pronotum with'a rather 

 wide oblique pale border, becoming very narrow basally and extending very finely 

 along the apex, with a small medial dilatation ; elytra each with a transverse pale 

 fascia extending from inner third or two-fifths to and enveloping the margin, its 

 posterior limit transverse and feebly sinuate, especially toward the margin, its an- 

 terior limit deeply sinuate, forming two acute points, one on the margin and one 

 on the medial line, the inner flank of the inner point straight and oblique ; legs 

 black; epipleurae with the outer edge black toward base. Length 5.0 mm.; 

 width 4.0 mm. Louisiana ; \_notulata var. B Muls.] notulata Muls. 



These two species seem to be amply distinct and not varietal forms 

 of one — at least no intermediate forms are known. This may how- 

 ever be another case of dimorphism. 



Cycloneda Crotch. 

 The type of this genus is the Coccinella sanguinea of Linne, de- 

 scribed from- Surinam. Sanguinea is therefore in all probability speci- 

 fically different from any of our forms, and it is not included in the 

 table given belovv. The species are all very closely allied ; they have 

 the elytra pale red or yellow or black and immaculate, those with 

 spotted elytra belonging to other genera. The metacoxal plates gen- 

 erally have no trace of the oblique dividing line, but in honditrasica
