I have not seen cramlidoides and it may not belong here. It was 

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

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

 Diatrcea, probably because of the absence of the ocelli. Whether it agrees 

 with Diatrcea in venation remains to be determined. 

 Diatraea alleni, n. sp. 



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

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

 fore wings, cream-buff. The hinder l)order of the fore wings as far as vein i, and a 

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

 surface of the wing is evenly and sparsely npiinkled with minute brown scales. Tiiere . 

 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 cream color but lighter on 

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

 lighter than the adjacent parts of the wings. Underside ot the fore wings, pale 

 fuscous with the brown terminal line reproduced. 



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

 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 the head and palpi 

 and the hinder edge of the fore wings as far as vein i, are somewhat li,;hter and the 

 fore wings are sprinkled with dark scales. There is a small dark brown discal spot 

 at the end of the cell and a terminal row of seven spots of the same color, the oi^e 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 pa'.e seal 

 brown, 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 the insect are similar 

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

 ference of color betw-een the two sexes as shown above is most remarkable. 



Described from two males and two females taken in Florida 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 }et feel [)ositive.
