and very constant, yet in many specimens of scalar is I have seen, there 

 is a strong tendency towards this torm. In regard to Crotch's paper, al- 

 ready quoted, 1 find another important exception to a specific character 

 given therein. He separates multipunctata Say, and its varieties from s/al- 

 aris and philadelphica, by its partially yellow prothorax. An examina- 

 tion of figure G will show that in this insect, a decided scalaris form, the 

 lateral margins of the prothorax are light yellow. This leads me to doubt 

 the validity of multipunctata as a distinct species, a doubt which Crotch 

 also expresses, though he gives no reason for it. 



Notes on Mexican Lepidoptera, with descriptions 

 of New Species. 



By Henry Edwards. 



(Fourth Paper.) 



I continue the descriptions of a few other fine insects collected by 

 Mr. Wm. Schaus, at Jalapa, Mexico, which, as far as I am able to ascer- 

 tain, are new to science. They certainly do not occur in any works to 

 which I have access, and I therefore think it best to place them on record. 



FAM. ZYGAENIDAE. 



Lycomorpha notha, n. sp. 



Form and size of L. pholvs, Dru. Wholly bluish-black with the exception of a 

 triangular patch at base of primaries, a very small patch at base of secondaries, collar, 

 palpi, and inside of fore femora, which are bright orange. 



I J 1 . 19. (No. 228.) 



Lycomorpha sinuata, n. sp. 



Allied to L. latercula, Hy. Edw. Head, antennre disc of thorax, abdomen and 

 legs all dull sooty black. Thorax with the sides and base, brick red. Primaries 

 brick red, with the margins sooty black, very narrowly so at the apex, broadest on 

 the median vein, thence straight to internal margin. Secondaries wholly sooty 

 black, except the base, which has a brick red patch. The markings are repeated on 

 the lower side. 



Exp. wings 24 mm. Length of body 10 mm. 1 9- (No. 230.) 



SUB-FAM. ARCTIIDAE. 



Gnophaela disjuncta, n. sp. 



Somewhat resembling at first sight the common G. vermiculata, G. & R. The 

 wings are however much narrower, and have a very striking greenish metallic sheen, 

 while the spots are totally different both in size and arrangement. Below the median 

 nerve is a narrow stripe, not cmite reaching the base, widening from a mere point to 

 immediately below the cell, where it is excavated, and surmounted by a rather large 

 .^ubovate patch, divided in half by the black median nerve. The apical patch is 

 large, cut into 5 spots by the nervures, that nearest the internal angle being a mere 

 dot. The secondaries have a large spot at the base, which is also divided into two 

 by the nerve, the lower being almost oblong; and the upper subtriangular in shape.
