it became impossible to obtain additional chinch bug eggs with 

 which to continue the work. From July 5 to July 23 only an 

 occasional parasitized egg was found in the field, but beginning 

 with the latter date, parasitized eggs were found in large numbers 

 in the cornfields, and the second generation was obtained by 

 August 10. Up to the present date this year over 275 individual 

 parasites have been bred out. The length of the life cycle has 

 been found to vary from ten to eighteen days, depending on the 

 climatic conditions. 



The parasite has been found in every wheat- and cornfield 

 examined around Manhattan. Of 3,101 eggs collected between 

 April 28 and June 10, the average per cent, of parasitism was 

 20.8, and of 116 eggs collected at Crawford (Central Kansas), 19 

 eggs, or 16.3, were parasitized. 



The work is still under way, and a full description of the 

 parasite, together with notes on its life-history and efficiency, will 

 be published later. 



A NEW SPECIES OF PHENGODES FROM CALIFORNIA 



(COLEOPTERA). 



BY HERBERT S.BARBER, BUREAU OF ENTOMOLOGY, WASHINGTON, D.C. 



With regret the writer feels forced to offer the description of 

 the following species in advance of its publication in a monographic 

 revision of the Phengodids now in manuscript, the appearance of 

 which has been delayed far beyond contemplation. 



Phengodes bellus, n. sp. 



Large, strongly bicoloured. Antennae (except two basal 

 joints), palpi, elytra and dorsum of last two abdominal segments 

 (except lateral margin) black; wings creamy white; all other 

 parts luteous. 



Length 20 mm.; width across humeri 3.8 mm. Habitat, 

 California. 



Occiput coarsely strigose; eyes separated above by slightly 

 more than twice the width of one eye as seen from above, below 

 by about one and one-fourth times the width of one eye as seen
