1907. BIRDS FROM GUATEMALA DEARBORN. 119 



mens make up the series. April 4th is the latest date of capture. 

 Adult males wore their regalia of red, blue and green all winter. An 

 immature male, taken March 3ist, had just begun to come into adult 

 plumage, a few blue feathers showing among the auriculars. This 

 bunting was seen at Gualan, and specimens were taken at Los Amates, 

 El Rancho, Mazatenango, Patulul and Lake Amatitlan. Iris dark 

 brown. 



213. Passerina versicolor (Bonaparte). 



An adult male was taken at El Rancho January sth. None were 

 observed elsewhere. Iris dark brown. 



214. Cyanocompsa parellina (Bonaparte). 



Two were obtained at Los Amates and two at Patulul. The 

 species was not common. This series comprises two adults of 

 each sex. Their bills are heavier than any of the half dozen speci- 

 mens from eastern Mexico with which they have been compared. 

 The females are considerably darker than those from Tamaulipas, 

 the back being between Vandyke brown and burnt umber. The 

 males have foreheads pale blue, and occiput and nape azure blue; 

 they also have a wash of azure on the lower breast, in each of these 

 particulars they differ from Mexican specimens. These specimens 

 are nearer subspecies parellina than any other that has been de- 

 scribed, both in size and color. The species has not heretofore been 

 recorded south of Mexico, but it extends at least as far as Nicaragua, 

 and when sufficient specimens from the southernmost portion of its 

 range are obtained, it is probable they will be found worthy of descrip- 

 tion and a name. When this has been done, these Guatemalan birds 

 will probably appear as intermediates. Iris dark brown. 



215. Guiraca czerulea lazula (Lesson). 



The western blue grosbeak was found to be generally distributed, 

 yet nowhere very abundant. Six specimens were taken, two from 

 El Rancho and one each from Los Amates, Patulul, Lake Amatitlan 

 and Lake Atitlan. An adult male, taken in January, has brown tips 

 to the body feathers, which only need to be abraded to put him into 

 summer dress. A young male, taken February 26th, has a few blue 

 feathers around each eye and one or two on its chest, which mark 

 the beginning of the spring moult. Another, taken just a month 

 later, has the crown, chest and sides of the neck mainly blue. Iris 

 dark brown.
