154 PROCEEDINGS OF THE NATIONAL MUSEUM vol.87 



LeConte's Latin description of Galleruca guttulata may be trans- 

 lated thus: Elongate, fuscous-testaceous, strongly cinereous pubescent, 

 densely and strongly punctate, with the short pro thorax widely 

 canahculate and uneven near the sides; elytra widely sulcate within 

 the humeri, obliquely impressed near the margin, with sparse, sub- 

 seriate, round black spots. Length 0.19 inch. One specimen only is 

 cited, and the type locahty for that given as San Francisco. Com- 

 pared with consputa, M. guttulata, according to LeConte, is larger and 

 the suture is not elevated and not dark. 



In the LeConte collection is a single female, with simple claws, 

 without doubt the one from which LeConte drew up his description, 

 which bears the label guttulata and a gilt circle indicating the locaUty 

 Cahfornia. It has also the Museum of Comparative Zoology type 

 No. 4384. The head is pale below, gradually darkening to deeper 

 yellow on the occiput, and the labrum and median line, which is not 

 much impressed, are dark. The pubescence is moderately long and 

 dense and conceals the occipital punctation. The four basal joints of 

 the antennae are pale and the remaining ones darker. The prothorax 

 is depressed in the middle and on the sides; the basal tooth is small 

 and not conspicuous; the pubescence long and appressed, nearly con- 

 cealing the dense punctation below. The elytral humeri are promi- 

 nent, with a long incurving intrahumeral depression extending a third 

 of the way down the elytra and a less marked postmedian lateral one. 

 The punctation is coarse, very dense, and partly concealed by the 

 dense, long, erectish, grajdsh-yellow hairs. The elytral markings 

 consist of small dark spots. Beneath, the legs are pale, the metaster- 

 num and first abdominal segments dark and shining under the fine, 

 dense pubescence. 



The most striking characteristic of guttulata, distinguishing it from 

 any of the other large species, is the long and somewhat erectish 

 elytral pubescence together with the conspicuous, long, intrahumeral 

 depression. M. guttulata is a little smaller than angularis and has a 

 different kind of elytral punctation, the punctures appearing rounder 

 and the surface less honeycombed than in angularis, and the pubes- 

 cence is long and not closely appressed as in angularis, and the antennae 

 are slenderer. M. consputa is smaller and not so pubescent. M, 

 debilis does not have the striking intrahumeral depression although 

 similar in its elytral punctation and debilis also has a longer prothorax. 

 The aedeagus of guttulata, similar in shape to that of consputa, is 

 longer. The majority of the specimens examined are heavily marked 

 with spots, often appearing nearly black. Thus far I have seen 

 specimens only from the region about San Francisco: Carmel, Monte- 

 rey, Ross, Lagunitas (Marin County), Los Gatos. Dr. E. C. Van 

 Dyke has collected it in numbers on a species of Artemisia.
