diverging to apex ; apices rounded ; the row of punctures moderarely coarse at base 

 finer at sides and apex, on the disk obliterated from about middle to apex ; intervals 

 finely not densely punctate ; surface rather sparsely pubescent. Metasternum rather 

 sparsely punctate, abdomen more densely. Length 10. 5-1 1.75 mm. 



Male. — Fifth ventral segment broadly emarginate ; sixth broadly emarginate, 

 the angles not prolonged. Last dorsal notched at middle. 



Female. — Fifth ventral less deeply emarginate than in the male ; sixth ventral 

 and last dorsal segments oval and subtruncate at tip. 



El Taste and Santa Rosa, Lower California, collected by Mr. 

 Gustav Beyer, to whom I am indebted for the pair. 



The abdominal characters of the male are very similar to ovipennis 

 Lee. but the sixth ventral is not nearly as deeply emarginate and the 

 impressed line above the notch of the last dorsal present in ovipennis 

 is absent in cephalica. 



Both angustata and cephalica differ from vandykei and ovipennis in 

 the apparently larger head, the less prominent eyes and the less 

 deeply constricted apical and basal third of thorax ; the latter is in 

 cephalica more shining, the punctuation very sparse and fine, while 

 the punctuation in all our other apterous species is very dense and 

 rather coarse. 



Trichodes illustris Horn, Proc. Cal. Acad., Vol. IV, p. 382. 



Nearly all the specimens of this species taken in the Huachuca 

 Mts., Arizona, have black legs and vary greatly in coloration. Some 

 of the varieties approach very closely peninsularis. 



Clerus corallinus Fall, Trans. Am. Ent. Soc, Vol. XXXIII, p. 240. 



This is a variety of abruptus. Mr. Leng has in his collection a 

 fine series from Texas with the necessary intermediate forms. Clerus 

 abruptus is a variable species in regard to coloration, markings and 

 punctuation and it seems to me tha£ flavosignatus, recutvatus and Icetus 

 are merely variations of abruptus, though Mr. Schenkling listed them 

 as distinct species in " Genera Insectorum." 



Hydnocera unifasciata Say, Journ. Acad. Phil., Vol. V., p. 175. 



One of my Arizona specimens is a little more robust than the aver- 

 age unifasciata and if seen alone without other specimens may be con- 

 sidered a different species, especially as the white fascia is absent and 

 the dense laterally directed hairs covering the fascia are easily abraded 

 in not well preserved specimens. This, however, is found also occa- 

 sionally in eastern specimens.
