(11.) Protaiidrena mexicanoruin (Ckll.) 



This is to be added to the United States fauua, as I took two 

 males on flowers of Aster spinosus in Mesilla, New Mex., July 21, 

 1896. The male may be known from that of asclepiadis by the 

 color of the stigma, but the two forms are to be considered geograph- 

 ical races of one species. 



(12.) Woinada liinata Cressou. 



Prof. Townsend took a female on Bldeiis at San Rafael, Vera 

 Cruz, March 8. It represents a variety with the marks more yellow, 

 and no spot on clypeus and pleura ; this agrees more nearly with 

 N. montezvma Smith from Orizaba, which is, I am convinced, only 

 a form of limaia. Cresson's name has priority. 



(1.3.) CalliopsiN reiiimaf'ulatus Ckll. 



I took one specimen of this at Las Cruces, New Mex., September 

 23, on GHtienezia sarothne var. microcephaki. It represents a slight 

 variation, with the yellow face-mark wholly supraclypeal. 



(14.) Calliopsis tricolor n. sp. 9-— Length about 9 mm., rather stout, 

 almost entirely naked ; black ; with the face-marks, tubercles, first four legs in 

 part, and abdominal bands, chrome-yellow; first abdominal segment largely ru- 

 fous. Head broader than long, vertex and front densely punctured, except a 

 broad, shallow groove in front of each eye; clypeus high, distinctly, but sparsely 

 punctured ; antennse black, flagellum becoming brown beneath ; mandibles with 

 a large, yellow, basal patch ; clypeus with its upper half yellow, the yellow send- 

 ing a rounded projection downward in the median line; supraclypeal yellow 

 mark quadrate, fully twice as broad as long, dog-ear marks well developed and 

 large; lateral face-marks consisting of a short, broad band, reaching from about 

 the lower margin of the yellow on the side of the clypeus to the top of the dog- 

 ear mark, joining these, but separated from the orbit by a narrow interval. 

 Thorax x-ather dull, minutely and strongly, but very closely punctured, median 

 and parapsidal grooves of the naked niesothorax distinct; hind margin of pro- 

 thorax with a narrow band of dull white pubescence; tubercles yellow; tegulae 

 reddish testaceous, with a small yellow spot. Wings smoky, outer margin broadly 

 darker, stigma orange-brown, nervures testaceous, costal nervure black ; marginal 

 cell with an abrupt, only slightly oblique, truncation ; .second recurrent nervure 

 joining second submarginal cell almost at its tip. Legs sparsely pubescent, 

 black; apical ends of first four femora, anterior tibise in front, and somewhat 

 more than the basal half of middle tibise, yellow ; basal joint of hind tarsi long 

 and flattened, with parallel side.s, minutely granular on outer side. Abdomen 

 strongly punctured, hind margins of segments 1-4 with rather broad yellow 

 bands, somewhat broader in the middle than at the sides ; first segment otherwise 

 rufous, with the base and a dorsal patch black ; venter dark, the margins of the 

 segments only slightly brownish.
