I ha\e not seen cramhidoides and it may not belong here. It was 

 described by Prof. Grote in the Canadian Fntomologist. Vol. XII, p. 15, 

 under the genus Chilo, but in his New List he put it under the genus 

 Diatra-a, probably because of the absence of the ocelli. Whether it agrees 

 with Dial) tea in venation remains to be determined. 



Diatraea alleni, n. ?p. 



Expanse of wingf, 30 mm. Head, palpi above and middle part of the collar, 

 cream white. Outer side of the labial palpi, sides ol the head and thorax and the 

 fore wings, cream-buff. The hinder border of the fore wings as far as vei 1 i, and a 

 few longitudinal streaks beyond the dark brown discal spot are paler and the whoie 

 surface of the wing is evenly and sparsely spiinkled with minute brown scales. There 

 is a fine dark brown terminal line somewhat broken. The frmges are whitish at the 

 base but darker beyond. The hind wings are of a sordid cieam color but lis^htcr oi> 

 the basal part. The dark brown terminal line does not reach the anal angle. F/uiges 

 lighter than the adjacent parts of the wings. Underside ot the fore wings, pa'e 

 fuscous with the brown terminal line reproduced. 



Described from one male taken in Orono, IMe., by the late INIr. 

 Anson Allen for whom I name this beautiful species. 



Diatraea differentialis, n. sp. 



Expanse of wmgs, 43 mm. in the males ; 541061 mm. in the females. Head, 

 palpi, antennae, thorax and fore wings, seal brown. The top of tiie h.^ad and palpi 

 and the hinder edge of the fore wings as far as vein i, are somewhat lighter and the 

 fore wings are sprinkled with dark scales. Theie is a small dark brown discal spnt 

 at the end of the cell and a termmal row of seven .'^pots of the same color, the one at 

 the anal angle being double. The hind wings are pale fuscous, lighter towards the 

 base which is of the same color as the abdomen. Underside of the hind wings like the 

 upper side in color and the underside of the fore wings a little darker. L -gs pale seal 

 l)rown, darker in front. 



The above description is from the male. The female has the head, 

 palpi, thorax and fore wings of a light brownish yellow color, the latter 

 sprinkled with brownish atoms. The discal and terminal spots are 

 similar to those in the male. The remaining parts of tlie insect are similar 

 to those in the male except that the shades incline to yellowish. The dif- 

 ference of color between the two sexes as shown above is most remarkable. 



Described from two males and two females taken in Floriiia in April 

 and May. 



These two species differ from saccharalis in having veins 11 and 12 

 separate though bent towards each other. Whether this is sufficient to 

 separate them generically I do not yet feel positive.
