PSYCHE. 



199 



black spots on vertex, and with h3-aline 

 eJytra, which have the external genitals 

 almost identical with those of sanguin- 

 nolenta. They were collected at Los 

 Angeles by Mr. Coquillett. I have 

 also specimens from Arizona collected 

 by Dr. Kunze. It will require the 

 study of large series from various local- 

 ities to decide whether it be really a 

 form oi sangziinoletita. 



Agallia californica n. sp. 



Lengtli 3-3.25. Intermediate between iikleri 

 and sanguiiioUiiia, the former of which it 

 clo.sely resembles in coloration. Acicnlation 

 of pronotuni finer than in ukleri, and punc- 

 tuation on vertex medially finer, sometimes 

 scarcely distinguishable. Hind margin of 

 last ventral segment in female trisinuate, the 

 median notch of varying size but always very 

 small. The plates of the male are rectangu- 

 lar, black at tips, and stand in nearly the 

 same plane, the apical margins often nearly 

 in one straight line; outer apical angles 

 obtuse, inner acute and minutely more or 

 less produced. The valve is short and very 

 broadlv evenlv rounded. 



Described from several specimens in 

 the Nat'l Museum, from Los Angeles 

 (Coquillett), one from Nevada Co., 

 Cal. (Koebele), and several from Telia- 

 chapi, Cal. (Morse). The form of 

 genitals readily separate this from a 

 large series of satiguinolentus and 

 uhleri from Colorado and various parts 

 of the East. It has a shorter-winged 

 form also found at Los Angeles, and 

 collected by Mr. Koebele in Placer Co., 

 Cal. 



Agallia lyrata n. sp. 



Male. Length 3.5. Very similar to cali- 

 forniciis but larger, the color and sculpturing 

 nearly the same as in that species. Valve 

 very short, shorter than in californicus, and 

 broadly rounded. Plates very long, outer 

 margins towards base strongly outwardly 

 bent, beyond strongly narrowed and running 

 parallel sided to the black rectangularly trun- 

 cate tips; taken altogether, distinctly lyrate. 



This species has been collected by 

 Mr. Koebele in Nevada Co., Cal. 

 Prof. Morse found it also at Wawona 

 and Teliachapi, Cal. Apparently a 

 very distinct species of the 7thleri 

 group. 



Agallia heydei n. sp. 



Form of A. constricia but larger. Length, 

 male 3.75, of female 4.25 mm. 



Female : Face a fourteenth longer than 

 wide. Front narrower than in 4-iiota/iis, 

 strongly constricted below the antennae. 

 Vertex about as long at the middle as at the 

 eyes. Pronotuni not quite twice wider than 

 long, length more than four times that of the 

 vertex. Last ventral segment suddenly con- 

 stiicted at middle, beyond this evenly bulg- 

 ing, then rapidly- narrowing to a shallowly 

 notched apex ; a semicircular depressed area 

 on either side of apical half. 



Color nearly as in 4-notatus. Brownish 

 with lighter aieas. Antennal cavities and 

 spots including the ocelli, black. Vertex 

 with two large black spots midway between 

 median line and eyes. Pronotuni with two 

 large black spots on posterior half. Elytra 

 with light veins on a brownish field. Ster- 

 num and basal portion of venter blackish. 



Male : Plates with sides evenly incurved to 

 middle; then enlarged towards the evenly 

 rounded, very obtuse tips.
