Tijfe locality. — Illinois. 



Type. — Walsh's type of this species is lost, but a single male speci- 

 men in the U. S. National Museum is labeled "Type of Ghalcis 

 olhifrons Walsh'* and bears the catalog number 1530. As this speci- 

 men was collected 8 years after the description was published, it 

 cannot be Walsh's type. Cresson redescribed this species in 1872, 

 but the specimens he had then very likely have been lost subsequently. 

 The two specimens now in the collection of the Academy of Natural 

 Sciences of Philadelphia labeled ''''Smifrt^a albifrons''' do not agree with 

 his redescription of the species. One is a female with the frons 

 almost entirely black ; the other is a specimen of Spilochalcis vielana., 

 new species, described on p. 316 above. The type in the National 

 Museum may as well, therefore, be considered as the neotype for 

 this species.

SPILOCHALCIS LEPTIS, new species 



Figures 9, n; 14, m 



This species is closely related to Spilochalcis side (Walker) but 

 differs in the male m having a shortx^r pedicel (fig. 9, n) and the lat- 

 eral ocelli located very near to the inner margins of the compound 

 eyes, not separated by a distance greater than the diameter of the 

 ocellus, as in side: the male has the entire frons ventrad and laterad 

 of the scrobe cavity yellow or whitish ; the female is difficult to sepa- 

 rate from the side female, but the large lateral ocelli located close to 

 the compound eyes, and the scrobe cavity extending to the anterior
