Arizona: Williams; Santa Rita Mountains; Chiricahua 
Mountains. Northern Mexico. 
This species differs from all others known to me in the com- 
plete coalescence of the ventral pits of the fourth and fifth seg- 
ments in the male. In all other species, the two foveae on each 
of the two segments mentioned are more or less completely sepa- 
rated by the membranous or semi-membranous median portion 
of the segment, which is frequently elevated in a cariniform 
manner in the dried specimens. In coelestinus there is a single 
transverse polished corneous fovea on each of these segments. 
Mr. Champion in his recent Revision of the jMexican and 
Central American Malachiidae, retains this species in Attains, 
but does not fail to note that the second joint of the anterior 
male tarsus of this species, and also of A . mexicanus, is not lobed, 
and remarks that they must come close to Tanaops. He seems, 
however, not to have noticed the ventral foveae of the male, a 
character pointing with considerable certainty to Tanaops. 
Champion mentions having seen one specimen of coelestinus with 
entirely red thorax. 
Tanaops complex new species 
Head black, margin of epistoma pale, prothorax entirely red, elytra blue 
green; body beneath black, the fourth ventral in the male red, with median 
black foveae; upper surface shining, the elytra less so because of the rather 
plentiful, pale, recumbent pubescence. Head not conspicuously elongate. 
Antennae moderate^ stout and serrate in the male, shorter, narrower and 
scarcely serrate in the female as usual. Prothorax distinctly transverse, sides 
strongly rounded, surface sparsely, minutely punctulate. Elytra finely, mi- 
nutely punctulate and sul>tuberculate. Legs black, the trochanters and front 
thighs more or less pale, especially in the male. Fourth and fifth ventrals of 
male with the usual median foveae near the hind margins small and dull, and 
anterior to these on each segment two larger, shining, rather deep impressions, 
which are confluent at middle. Length 3 to 3.25 mm. 
Arizona: Santa Rita Mountains, 8000 feet. A single pair 
communicated by the late Prof. Snow. 
Tanaops repens new species 
Red, strongly shining, posterior half of head, black, a common basal spot 
and an elongate subapical spot on each elytron greenish black; antennae, sides 
of metastemum, legs in part, the sixth ventral and sides of the fifth, black. 
Head about four-fifths as wide as the thorax, numerously, finely punctulate.
