Records of Dees. L09 



Bupraclypeal area with only the lower corners pale ; axillae 

 black ; wings clear hyaline basally ; band on second abdo- 

 minal segment (narrowly interrupted in middle) more 

 slender. 



Hub. San Jose del Cabo, Lower California. U.S. National 

 Museum. 



This is evidently from the same lot as those recorded by 

 Fox, Proc. Calif. Acad. Sci. ser. 2, vol. v. p. 270, as a variety 

 of D. not at urn. A relative in California is D. robertsoni, 

 Ckll.j but that has differently formed and coloured markings. 



Ant Iridium 22-punctatum, Friese. 



<J ?. Guayaquil, Ecuador (v. Buchwald). Alfken col- 

 lection, 9. 



Friese's measurements are too small, unless applied 

 to specimens with the abdomen contracted and turned 

 downward. In my female the outer spots on the fifth abdo- 

 minal segment are mere dots. The species belongs to 

 Anthidium, s. str., and closely resembles various North- 

 American species, from which it is readily known by the 

 5-dentate apex of male abdomen. 



Agapostemon nasuius, Smith. 



4 £ . Guayaquil, Ecuador (v. Buchwald). Alfken col- 

 lection, 13. These are quite typical. 



Centris nigerrima (Spinola). 



Chile. Anthoplwra dimidiata, Smith, is a synonym, as 

 shown by a specimen in my possession, from Y. Smith's 

 collection. 



Centris euphenax, sp. n. 



? . — Length about 15 mm. 



Kobust ; head, thorax, and legs black; abdomen with 

 the first three segments black with a very obscure bluish 

 tint, the hind margin of the third reddish ; remaining 

 abdominal segments bright ferruginous red ; clypeua shining, 

 sparsely punctured at sides, cream-coloured except the broad 

 lateral and upper margins (the cream-coloured area coming 

 to a point above) and the linear l)rown lower edge : labrum 

 cream-coloured except the narrow lateral and apical margins, 

 its hair black ; eyes moderately converging above : hair of 

 whole insect entirely black, except on the red (apical) part
