Species of Neotropical Coccinellidae. 321 



Trinidad: Cedros, April 1911 (F. W. Un'ch). 



Type in the British Museum. 



TJescribed from five specimens received by tlie Entomo- 

 logical Kesearch Committee from Mr. F. W. Urich, Ento- 

 mologist to the Board of Agriculture, Trinidad. Mr. Urich 

 states that the species is of economic importance, as both tiio 

 adults and larvae attack the coconut scale {Aspidiotus 

 destrucloi-), upon which they operate as a very serviceable 

 check. 



This species may be readily distinguished from all the 

 previously described species of Azya by its small size and by 

 the complete absence of any of the characteristic patches of 

 dark hairs. 



Azya nana, sp. n. 



Parva, cyanea, nitida ; abdomine, pedibus, ore rufo-flavis ; supra 

 setulis griseis subreclinatis vestita, elytris ante medium macula 

 circular! communi setulis fuscis brevioribus suberectis obsita 

 ornatis. 



Dark blue, shining ; the abdomen, legs, and mouth-parts 

 reddish jellovv. The upper surface is densely clothed with 

 fine subrecumbent grey hairs, which are rather longer than 

 those of A. trinitatis, and on the elytra there is, before the 

 middle, a common circular patch of rather shorter suberoct 

 dark hairs; the front margin of the patch does not quite 

 reach the scutellum, and its hind margin is just behind the 

 middle. The punctation is very similar to that of A. tnni- 

 tatis, but is distinctly shallower on the disk of the elytra. 



Length 2*25 mm. 



Beazil : Pernambuco {Alexander Fry). 



Type in the British Museum. 



The two Brazilian species, A. scutata, Muls. (3'5 mm.), 

 and A. nigrina, Weise (4 mm.), which agree with A. nana in 

 having a common patch of dark hairs on the elytra, may be 

 at once distinguished by their much larger size, reddish- 

 yellow epistome, and less strongly punctate elytra, as well as 

 by their different colour — the first-mentioned being black 

 with a dark purplish reflection, and the other entirely black. 

 I have seen sixteen specimens of this species. 



Cryptognatha nodiceps, sp. n. (Fig. 2.) 



Parva, flava, signaturis piceis notata ; elytris singulatim litura 

 magna irregulari picea discum fere totum obsideute (vide fig. 2) 

 et macula parva elongata longitudinali ante medium juxta suturam 

 ornatis.
