Texas, and have restricted the name strcckcri to the Arizona speci- 

 men, as it bears the actual "type" label ; specimens from S. Colorado 

 have been compared with this type and agree in every respect. With 

 regard to the two other "type" specimens mentioned in Skinner's 

 description, we learn from Dr. Skinner himself that he never had 

 these specimens before him at the time of description but placed them 

 under streckcri on the authority of Strecker. We have seen these 

 two "types" in the Strecker collection ; the one, a $ , belongs to the 

 Texan form, and is probably one of the specimens which Strecker 

 erroneously described as the $ of cofaqui (Bull. Brook. Ent. Soc, 

 III, 66) ; the other, an enormous 9 , we also consider to be a rather 

 aberrant and strongly marked individual of this form ; it is doubtless 

 one of the 9 specimens mentioned by Strecker (Lep. Rhop. & Het. 

 135) as having been taken in "May, 1876, by the expedition under 

 Lieut. E. H. Ruffner during the surveys and explorations of the 

 region of the head waters of the Red River of Texas. They were 

 taken in the Llano Estacado or Staked Plains." Skinner's original 

 description states that the 9 is from the "San Juan reconnaissance 

 made under the charge of Lieut. Ruffner, Colorado, in 1877." This 

 is probably due to a slight confusion of the two expeditions, as 

 Strecker in his report on the Lepidoptera taken in this latter expedi- 

 tion makes no mention of any Mcgathymus species.
