Records of Dees. 557 



nieiliau tooth triangular, i)roa(l and short; fiith ventral 

 segment with a pair of strong sharp a])ical spines. The end 

 of the abdomen resembles that of C. azttca, but the median 

 tooth is much shorter and broader. 



llah. Quirigua^ Guatemala, Feb. 10, 1912 ; one of each 

 sex (//; P. CovkercU, 16). 



Tiiis was taken with true C.aiaabilis, Ckll., but the colora- 

 tion is peculiar, and it seems best to give it a varietal name. 

 In certain lights the gold of the abdomen shines greenish. 



Ceratina loilmattce, sp. n. 



? . — Like C. amabilis, but perhaps usually larger ; the 

 abdomen of a darker crimson-red, less strongly and densely 

 punctured, especially on the fourth segment ; wings ver^ 

 red ; green of head and thorax more or less suffused with 

 golden ; vertex, and mesotliorax more or less, dark bronze ; 

 pale spot on clypeus short though large, not much longer 

 than broad ; no lateral clypeal spots ; anterior tibiie with a 

 yellow spot at base, but no stripe. 



Hah. Quirigua, Guatemala ; two at yellow golden-rod-like 

 flower {IV. P. Cockere/l). 



Very close to C. amabilis, but, I believe, distinct. 



Ceratina ignara, Cresson. 



Two females and a male from Lake Amatitlan, Feb. 5 

 {IV. P. Cockerel/), must surely belong to iynara, as the 

 females agree closely with Cresson's description. Compared 

 •with a specimen of C. abdominalis, H. S. Smith (from the 

 type lot), they are almost identical, except that the wings 

 are not nearly so dark, and especially not so red. The male 

 (unknown to Cresson) differs considerably from Smith's 

 account of male abdoininalls, having the following salient 

 characters : — Eyes very prominent, converging below ; 

 clypeus light yellow except the broad lateral margins ; 

 small elongate lateral face-marks, away from eye, pointing 

 obliquely upwards and racsad ; labrum black, with a minute 

 pale dot ; mandii^les black, with the apex dark red ; end of 

 abdomen with a little tuft of hair ; seventh segment pro- 

 duced into a very large broad truncate plate, very shallowly 

 emarginate in the middle. The clypeal mark in the females 

 is large. The sides of the apical plate in the male are much 

 less sloping than in abdominalis.
