34 INSECUTOR INSCITI/E MENSTRUUS 



the surface vestiture. In the table which follows I am unable to include 

 the European species, C. grandicorne Rondani, as I have seen no speci- 

 mens and the description is insufficient. As pointed out by Rondani, the 

 antennae are considerably broader in the male than in the female, and 

 this appears to be particularly noticeable in icerya, edthough even here 

 the difference is not as great as indicated for the European species by 

 Rondani's figure. 



TABLE OF SPECIES 



1 . Wing elongate ; bend of fir^t vein rounded, second and third veins diverging 



very gradually, the submarginal cell narrow .... icerya Will. 

 Wing broad ; first vein more or less angulate, second and third veins strongly 

 divergent, the submarginal cell broad ....... 2 



2. Anterior cross- vein usually before end of first vein, posterior cross- vein dis- 



tinctly arcuate, the convexity toward the second posterior cell ; antennas 

 with the third joint rounded or with an obtuse point . monophlebi Skuse 



Anterior cross-vein about in line with end of first vein, posterior cross-vein 

 recrilinear ; third antennal joint produced to a sharp point . curtipenne, n. sp. 



Cryptochaetum iceryae Williston. 



I have not seen the type of this species and do not know if it is still in 

 existence. I restrict the species in accordance with the figure given by 

 Williston in connection with his original description, and with the restric- 

 tion made by Skuse. It is at once recognizable by the more elongate 

 wings, which finds tangible expression in the longer and narrower costal 

 cell, in the approximation of the second and third veins, and in the more 

 distal position of the anterior cross-vein. The posterior cross-vein is rec- 

 tilinear. The Cryptochcetum material sent from Australia is now repre- 

 sented in the national collection by a scant 1 3 specimens, mostly in very 

 poor condition, from Professor Koebele. Of these I am able to refer 

 six here with certainty. This species is said to be now common in south- 

 em California (Essig : Monthly Bull. Cal. State Comm. Hort., vol. 2, 

 p. 250, 1913), but I have seen no Califomian specimens that I can refer 

 here and so am unable to say whether this species is established there. 

 See remarks under the following species. 



Cryptochaetum monophlebi Skuse. 



I have specimens before me from Australia and Tasmania which I 

 believe are referable to this species. Three of them are from the Koe- 

 bele material and three others from Perth, West Australia, collected by 

 G. Compere ; eight specimens in poor condition are from Tasmania, from
